GENERAL INFORMATION ===================================================================== 1.1. Subject : Obtaining the Windows NT beta release Question : How can I get the beta version of Windows NT? Answer : There are two programs: The Win32 Preliminary SDK for Windows NT and the Windows NT Beta program. I. Win32 Preliminary SDK for Windows NT The Win32 Preliminary SDK for Windows NT is offered for software developers who need to either develop applications for the Windows NT operating system or to port existing applications to 32-bit. The Win32 Preliminary SDK for Windows NT provides you with access to the broader capabilities of the Win32 API with features such as preemptive multitasking, multi-threading, 32-bit flat memory model,and security. By purchasing the Win32 SDK you will receive preliminary and final versions of the Windows NT operating system and SDK tools in addition to preliminary versions of a C/C++ compiler. For complete system requirements please download the Win32 Preliminary SDK data sheet (SDKDAT.DOC or SDKDAT.RTF in Library 1 of the MSWIN32 forum) and the hardware compatibility list (1092HW.TXT in Library 1 of the WINNT forum). The cost of the Win32 SDK with printed documentation is $399. A CD-only version containing the documentation in PostScript format is also available for $69. To order from within the U.S, please call Microsoft Developer Services at (800) 227-4679 ext. 11771. In Canada, call (800) 563-9048. In all other countries, contact your local Microsoft representative. II. Windows NT Beta Program Distribution of Microsoft Windows NT, October Beta is currently only available to a limited number of sites. However, we will increase the number of beta sites over the coming months. If you wish to register your interest in the program, you may choose to do one of the following: 1) Send a letter to Microsoft Corporation One Microsoft Way Redmond, WA 98052 Attention: Microsoft Windows NT Beta Program 4/1 2) Send a facsimile to (206) 936-7329 to the attention of "Microsoft Windows NT Beta Program, 4/1". Please send only typed or printed submissions. In either case you should include: Name: Company Name: Title: Address (no p.o. boxes): Phone/Fax#: Hardware configuration: Any other related information: This does not automatically ensure your enrollment in the Beta program, however we will seriously consider all inquiries. ===================================================================== 1.2. Subject : Getting LAN Manager for Windows NT Question : How do I get on the beta program for LAN Manager for Windows NT? Answer : Distribution of Microsoft LAN Manager for Windows NT, October Beta, is currently only available to a limited number of beta sites. However, we will increase the number of beta sites over the coming months. If you wish to register your interest in the program, you may choose to do one of the following: 1) Send a letter to Microsoft Corporation One Microsoft Way Redmond, WA 98052 Attention: Microsoft LAN Manager for Windows NT Beta Program 4/1 2) Send a facsimile to (206) 936-7329 to the attention of "Microsoft LAN Manager for Windows NT Beta Program, 4/1". Please send only typed or printed submissions. In either case you should include: Name: Company Name: Title: Address (no P.O. boxes): Phone/Fax#: Hardware configuration: Any other related information: This does not automatically ensure your enrollment in the Beta program, however we will seriously consider all inquiries. ===================================================================== 1.3. Subject : Manuals for the Windows NT SDK update Question : I didn't get any manuals or release notes in my SDK update for October. How do I get them? Answer : Documentation for the SDK is included on the CD-ROM in the \DOC\ENDUSER directory. Please check the README.TXT in the \DOC directory for a complete listing of Programming References and other documentation that is included with your CD-ROM. ===================================================================== 1.4. Subject : Support via a Internet Address Question : Is there an Internet address that I can submit questions to? Answer : No - at least not with full MS support. The only official location for support from Microsoft is on CompuServe in the WINNT and MSWIN32 forums. However, there are several other places where you can get some peer support, (including some MS personnel in their own time). These include the ntdev@alfalfa.com mailing list (send mail to ntdev-request@alfalfa.com to join) and the comp.os.ms-windows.programmer.win32 newsgroup on UseNet. Please remember that these are not official venues for support, and as a result support is not guaranteed and the level of support you do receive may vary. ===================================================================== 1.5. Subject : Development Issues belong in the MSWIN32 Forum Question : Where should I ask questions about the Win32 SDK? Can I ask them WINNT Forum? Answer : SDK programming questions are answered in the MSWIN32 Forum. WINNT is dedicated to end-user issues about Windows NT (for example installing/setting up the Windows NT operating system itself), MSWIN32 is dedicated to developer issues about Windows NT (for example installing/setting up the SDK for Windows NT, API questions, etc) The more we can all stick to the organization for the forums/sections that the release notes mention, the easier it will be for all forum readers to efficiently get to the info they need. Thanks! ===================================================================== 1.6. Subject : Obtaining the Windows NT DDK Preliminary release Question : How can I get the Preliminary Release of the DDK for Windows NT? Answer : The Preliminary DDK will be available before the end of November. The cost is as follows: DDK CD-ROM only $69 DDK CD-ROM with hard-copy documentation $399 This pricing includes updates and the final version of the DDK. The documentation will be included on the CD in both Postscript and Write format, and all the device driver functions will be documented in Winhelp. If you are in the US and currently own the Win32SDK, you will be receiving a mailing on the DDK in mid-November which will include 4-page product datasheet and an order coupon. To order from within the U.S, please call Microsoft Developer Services at (800) 227-4679. In Canada, call (800) 563-9048. In all other countries, contact your local Microsoft representative. International customers should contact their local MS office for ordering, pricing and availibility information. One other important change which you should be aware of. Everyone who purchases the hard-copy documentation for the DDK will receive the new book "Inside Windows NT" from MS Press. This book will not be on the CD. ===================================================================== 1.7. Subject : Making a Suggestion to be added to Windows NT Question : I would really like to see this feature added to Windows NT. How do I go about making this suggestion? Is there a mechanism available to make such suggestions? Answer : The method for filing bug reports can also be used to make suggestions for the Windows NT system. You can file this report by using the BUGREP.TXT template from Library 3 (Problem Reports) of the WINNT forum and uploading the completed form to the same library. This report will be passed to the Windows NT development team so they can evaluate the suggestion. More detailed instructions for reporting bugs can be found elsewhere in this document and a SAMPLE.TXT is available for your convenience. ===================================================================== 2. INSTALLATION AND SETUP ===================================================================== 2.1. Subject : Flexboot keeps returning to Flexboot instead of MS-DOS. Question : Whenever I select the Flexboot to boot MS-DOS it keeps returning me to the selection menu? Answer : This happens when installing Windows NT over a previously existing Windows NT installation without doing a MS-DOS SYS C: to the active partition. When Windows NT installs it will read the boot sector from the drive and create a BOOTSECT.DOS that Windows NT will use when you select the PREVIOUS operating system choice. If, for some reason, the install process reads a Windows NT boot sector and uses this to create the BOOTSECT.DOS, it will use the previous Windows NT boot sector when you select the Previous operating system from Flexboot. There are two ways to fix this: 1) If you have a previous copy of BOOTSECT.DOS, simply replace the current version with the previous version. 2) If not, you will need to recreate the boot sector for MS-DOS by booting from a MS-DOS diskette and executing SYS C: from that disk. Doing this will also remove the Flexboot feature from your system and you will need to reinstall Windows NT to re-enable this feature. ===================================================================== 2.2. Subject : NT Boots, Looking for the Wrong Boot Directory: Question : Windows NT looks in the wrong boot directory. Why? Answer : This can happen for a few reasons. 1) There has been an installation of the Beta release over an earlier release of Windows NT. The boot.ini file is not updated correctly. Solution: Make sure that the boot.ini file contains references to the WINNT directory rather than the NT directory i.e. C:\WINNT\ rather than C:\NT\ 2) The IBM MOST utility for OS/2 2.0 is installed on the hard drive. Windows NT uses logical partitioning. The MOST partition is an unknown partition type. When an unknown partition type sits between the base partition and the Windows NT partition, it can set the logical partitions off by one. MOST is not supported with Windows NT. You should install Windows NT on a machine that does not have the MOST utility installed. ===================================================================== 2.3. Subject : NTFS on MIPS R4000 Question : Can I convert my MIPS system partition to NTFS? Answer : No. The ARC specification requires that the system partition be FAT. This is done so that HAL.DLL and OSLOADER.EXE will be accessible regardless of the media type. If you want to use NTFS on a MIPS machine, create a small system partition (1M or larger) to hold HAL.DLL and OSLOADER.exe. The rest of the disk can be used as an NTFS partition. The installer correctly puts HAL.DLL and OSLOADER on the system partition. Note: DO NOT use CONVERT.EXE on the system partition. It will convert it to NTFS and the system will not boot. If this happens, your only option is to run ARCINST.EXE from the install CD-ROM and reformat the system partition as FAT. ===================================================================== 2.4. Subject : Windows NT needs 600K free Question : When I start up Windows NT, it gives the following error : Windows NT has found only xxxxK of low memory, 600K of low memory is required to run Windows NT. You may need to upgrade your computer or run a configuration program provided by the manufacturer. Answer : In order to start Windows NT there must be at least 600K of low memory to start it. You may have to do some configuration changes to get this to work correctly. ===================================================================== 2.5. Subject : PS/2 Model 90 Locks up or has BOOT I/O error on install Question : When I am installing the October beta release of Windows NT on my PS/2 model 90, right after it copies default.$, it either locks or returns a BOOT I/O error. Answer : The Microsoft Windows Nt product group has recently identified a setup problem with the October Beta Release of Windows NT. On certain IBM PS/2 and MCA bases systems, an error may occur during the installation. The installation of Windows NT is prevented when this error message appears : "BOOT I/O reading Disk. Please insert another disk" The problem occurs due to a conflict between the setup program, the native BIOS, and the SCSI level of the system. Our development and test groups are working on a permanent solution. In the interim, we have made a file available that should provide a temporary workaround until the problem has been resolved. The workaround can be found in Libary 2 of the WINNT Forum and is called WNT001.ZIP. Additional instructions can be found there. =========================================================================== 2.6. Subject : PS/2 hangs when searching for SCSI adapter Question : While installing the October beta release of Windows NT on my PS/2, it hangs right after it searches for 3rd party SCSI adapters. What should I do? Answer : Check to see if your IBM SCSI adapter has a 1991 BIOS chip. At this time, it is not possible to install the October Beta release of Windows NT on a machine that has this chip set. It will be necessary for you to use either another supported SCSI adapter or an IBM adapter with a BIOS date other than 1991. You may check the date of your SCSI BIOS by examining the card and looking at the end of the adapter closest to the front of the machine. You should be able to see a chip that has a paper sticker on the contains the SCSI BIOS date. ===================================================================== 2.7. Subject : $WIN_NT$.~LS directory Question : After I attempted to install, Windows NT left a directory named "$WIN_NT$.~LS" on my hard disk. What is it? Is it OK to delete it? Answer : This is a temporary directory created by the WINNT.EXE installation program. The WINNT.EXE program copies all the setup files it needs to your hard disk, then reboots into Windows NT and runs setup off of your hard drive. When Setup is completed, it should remove these temporary files, but if you encounter an error during setup or when setup tries to remove these files, they will remain on your disk. In any case, it is OK to delete the entire $WIN_NT$.~LS tree from your hard drive. ===================================================================== 2.8. Subject : Setup fails when booting from text to GUI setup See Fatal Kernel Errors 0000006E and 00000071 in the "COMMON ERROR MESSAGES" section. ===================================================================== 3. HARDWARE INFORMATION ===================================================================== 3.1. Subject : System Requirements Question : What are the minimum hardware requirements to run Windows NT? Answer : Windows NT operating system: The first beta release Windows NT operating system requires an Intel 80386 system or higher with at least 8 MB of RAM (12 MB is recommended for this release), or ACE/ARC compatible RISC-based computer with 16 MB of RAM such as a MIPS R4000. This system should have about 35 MB of free disk space for Windows NT, plus 20 MB for virtual memory paging file. This does not include disk space for applications. Win32 SDK development environment: For Win32 SDK development, an 80386 33 MHz CPU (or higher) and 12MB total of RAM is strongly recommended. A total of 100MB available hard disk space (includes 20MB for a swap file) is required for complete installation of the operating system, SDK tools, and C/C++ compiler. The Win32 SDK is only available on CD-ROM and requires a CD-ROM drive and SCSI adapter. ===================================================================== 3.2. Subject : Hardware Compatibility List (HWFEED.TXT) Question : How do I know if my hardware is supported and what do I have to do to get support? Answer : Microsoft provides a list of hardware that has been tested and is known to work with Windows NT. It has been posted on Compuserve, forum WINNT, Library 1, filename : 1092HW.TXT. For your convenience the hardware list is also available in Word for Windows format and called 1092HW.DOC. The Hardware listed in this file has been tested on the October release of Windows NT and is supported. Microsoft does not claim that hardware not on this list will not run; however, it has not been tested and it is not supported at this time. If you would like to get support for your hardware, in the WINNT forum, Library 1, there is a form - HWFEED.TXT. Fill out this template with the hardware you need support for and mail it via CompuServe mail to the Internet address listed in the form. Information from these surveys is compiled by the development team to help clarify where support is needed most. Also, since many drivers are being written by third party companies, contact your vendor to indicate that you need a driver for their hardware to run under Windows NT. This will help expedite the process external to Microsoft as well. ===================================================================== 3.3. Subject : MIPS Installation Question : Windows NT will not work on my MIPS machine. Answer : The October release of Windows NT requires an upgrade to your MIPS machine. All manufacturers are aware of this upgrade. If they have not contacted you already, please contact them regarding it. The machine's CPU must also have an R4000 revision 2.0 or greater. ===================================================================== 3.4. Subject : Full Screen MS-DOS Support for MIPS Question : How do I get Full screen MS-DOS support on my MIPS Machine? Answer : Full screen support is not and will not be provided with Windows NT on MIPS systems. ===================================================================== 3.5. Subject : Device Driver Requests Question : Is there a driver yet for my hardware? Answer : Microsoft's standard means of releasing drivers is with their CD releases. Although Microsoft is not committed to continue this practice, currently all fixed, updated, or new device drivers are being posted on the CompuServe Forum: WINNT, Library 2. Microsoft is currently making every attempt to keep this library updated with drivers as they become available. If you have hardware that is not currently supported, or does not have a driver posted in WINNT, Library 2; please make a device driver request by filling out the HWFEED.TXT form (appendix B to this FAQ) and mail it to Microsoft at winnthw@microsoft.com. ( "internet:winnthw@microsoft.com" if you are sending mail from CompuServe). Please be aware that because of Microsoft's support demands right now, this is a one way alias; Microsoft will not respond directly to you to confirm that they have received your request. The hardware compatibility list and HWFEED.TXT file can be found in WINNT, Lib 1 on CompuServe as 1092HW.TXT and HWFEED.TXT. ===================================================================== 3.6. Subject : DELL Machine Only Recognize 16 MB of Memory Question : Windows NT does not recognize memory above 16MB on my Dell machine. Answer : The ISA Dell 486D/50 25/50Mhz has a BIOS problem which prevents it from seeing greater than 16MB of RAM under NT. The ISA Dell 486D/50 25/50Mhz machine does not see greater than 16Mb of RAM under Windows NT. This is a known problem with the BIOS of the Dell machine. If your machine demonstrates this problem, please contact Dell to receive their A08 BIOS upgrade. ===================================================================== 3.7. Subject : Bernoulli and Removable Media Not Supported Question : Can I use my Bernoulli drive even though it is not listed in the hardware compatibility list? Answer : Bernoulli boxes and removable SCSI drives were not tested with this release of Windows NT, and do not appear on the hardware compatibility list. Since the release there is evidence that Windows NT has some problems with these devices. Microsoft is aggressively pursuing this matter in hopes of having it resolved by the next release. ===================================================================== 3.8. Subject : Adaptec AHA 1542B Driver Can Cause Fatal System Error Question : Help! I am having problems and I have an Adaptec controller. Answer : There is a known problem with the Adaptec AHA-1542B driver which causes fatal system errors under some circumstances. The problem is triggered by simultaneous I/O with the floppy and the hard disk. This will be corrected in the next release. To avoid this you may want to use an alternative floppy controller and disable he one on the Adaptec. ===================================================================== 3.9. Subject : SoundBlaster/AudioPro Question : How can I get my SoundBlaster/AudioPro card working properly? Answer : Many times this problem can be solved by installing the Creative Labs driver supplied on the Windows NT Setup CD. However, there are some 486 systems and some system chip sets that are not fully compatible with the SoundBlaster/AudioPro card. If find the following answer does not get your SoundBlaster card working - file a bug report. 1) The Creative Labs Sound Blaster driver may not be installed yet. You may use the Control Panel's Drivers option to install the Creative Labs Sound Blaster 1.X driver (that is provided on your Windows NT CD) After installing you should configure the driver for the proper IRQ and address. 2) There may be an IRQ conflict with another device. Either change the IRQ setting on the other device or on the sound card. The default settings for the sound card is DMA 1, IRQ 7 and port 220h (note however that LPT1 also uses IRQ 7). We suggest physically changing the SoundBlaster to IRQ 2 and then using the Control Panel's Drivers option to reconfigure the Creative Labs Sound Blaster 1.X driver to IRQ 2. 3) You can play WAV files but not MID files. This usually means you still need to install the AD-LIB MIDI driver. The MIDI driver may be installed via the Control Panel's Drivers option. ===================================================================== 3.10. Subject : Cannot Print to LPT1 Question : I cannot print to LPT1:! If I type "MODE LPT1:" it claims the device is not found. What is wrong? Answer : Typically LPT1: uses interrupt 7 which is also the default setting of the SoundBlaster sound card. You may be experiencing a IRQ conflict with this or another device. If you are unable to resolve the conflict you can disable one of the devices in the Registry. The utility REGEDIT is provided to alter the Registry Database. Note: in many cases you must be logged on as 'Administrator' to alter some of the Registry settings. Hardware configuration (driver) settings can be altered under the Registry branch: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services. The SoundBlaster can be disabled or enabled by changing the value of the "Start" entry for ...\Sevices\Sndblst to the appropriate start value (Start=0x4 to disable, Start=0x1 to enable). Similarly, the parallel driver can be disabled/enabled by changing the "Start" entry for ...\Services\Parallel to 0x4 or 0x1 as above. ===================================================================== 3.11. Subject : Installing a CD player after Windows NT has been installed. Question : If you install a new CD player after Windows NT has been installed, what section of the registry do you edit so that NT recognizes the new CD? And what are the values? Answer : The utility REGEDIT is provided to alter the Registry Database. Note: in many cases you must be logged on as 'Administrator' to alter some of the Registry settings. Hardware configuration (driver) settings can be altered under the Registry branch: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services. Make sure the driver for your SCSI adapter is enabled by checking that the "Start" value for it is set so "Start=0". Also be sure to set the "Start" value for SCSICDRM to 0. You can find this listed under "...\Services\Scsicdrm". If the drive doesn't support SCSI-2 CD Audio, then you may want to enable the CDAUDIO driver as well. You can find this listed under ...\Services\Cdaudio. ===================================================================== 3.12. Subject : Activating CD Audio Question : My supported SCSI CD-ROM drive doesn't play AUDIO CD's, what should I do to get it to work? Answer : The scsicdrm.sys is the primary SCSI CD-ROM driver supplied by Windows NT. This driver covers most SCSI-II CD-ROM drives and should work under the following conditions. 1) The drive is a SCSI-II CD-ROM drive. 2) The SCSI controller is supported and NOT Fd850 (sorry). (a bug has already been filed on the FD850 SCSI controller) 3) The scsicdrm start value is enabled in the registry. You may check this by running REGEDIT. The information is under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Scsicdrm. The Start value should be set to 0 for this key (0x4 = disabled). * Please reboot for the new Registry start value to take effect NOTE: There are some SCSI-I drives that are supported through CDAUDIO.SYS (Pioneer DRM-600, NEC Intersect, Denon, and Hitachi are just a few). This driver can be enabled in the Control Panel. The CDAUDIO.SYS should be enabled in addition to SCSICDRM.SYS. The CDAUDIO key is under .....\Services\Cdaudio. The CDAUDIO Start value should be set to 1 to enable this special driver. ===================================================================== 3.13. Subject : SCSI and ESDI drives greater than 1024 cyl. Question : Can you have SCSI drives and ESDI drives > 1024 cyl. Answer : ESDI uses CHS (cylinder, sector, head) address. SCSI uses RBA (relative block address) addressing. Normally, you do not worry about a 1024 cylinder limit with SCSI, until the SCSI drive becomes very large (> 1 GB). Then there is a problem. Some SCSI cards have a jumper for > 1GB support. Find out if your card can assert this jumper. The ESDI interface has a 1024 cylinder limitation. Some controller cards get around this by implementing a translation scheme in the onboard controller BIOS. Windows NT (and other protected mode OS's) must duplicate the code found in these BIOS chips inorder to duplicate this behavior. Unfortunately, there are many ways of performing this translation and thus we must incorporate all of these schemes in our standard AT disk driver. As you have probably guessed by now, we have not included such support for all known ESDI translation schemes. Some ESDI controllers implement this translation in hardware thus it is totally transparent to the system allowing the standard driver to work unchanged. Consult your controller's documentation to see if such translation is performed by the BIOS or the hardware. ===================================================================== 3.14. Subject : Windows NT will not install on IBM PS/2 Model 90 and 95 Systems Question : Why do I get the following error when installing Windows NT: BOOT: I/O Error reading disk Please insert another disk Answer : Windows NT will not install if the configuration includes an IBM SCSI adapter card with the 1991 BIOS chip. In order to install you need the IBM SCSI adapter card with the 1990 BIOS or another type altogether. To determine if your machine has this adapter card open up your PS/s and look at the SCSI card. At the edge of the card towards the front of the machine is a chip with a white label on it. If it is dated 1991 then you may not be able to install the October release. ===================================================================== 3.15. Subject : Soundblaster Pro only supported in Mono mode Question : My Soundblaster PRO will only play in Mono! Why? Answer : The SoundBlaster Pro is only supported in Mono mode in the October Release. This support is provided through version 1.x of the SoundBlaster drivers. Work is currently in progress for a Windows NT driver that will support SoundBlaster Pro in stereo, however, there is no word on the availability of such driver at the current time. ===================================================================== 3.16. Subject : Additional Video drivers like the 8514 and ATI Ultra Question : Why isn't there a video driver supplied with the October Release of Windows NT to support my 8514 or ATI Ultra? How do I get one? Answer : Microsoft is aware that many of our customers require additional video drivers like the 8514, the ATI Ultra and 256/32768/65536 color SVGA drivers We are sorry to say that these drivers are not available at this time. After these drivers have been completed and passed testing, we will release them to the the public. We are sorry for any inconvenience that this may be causing you and are working to complete them as quickly as possible. Please see the Hardware Compatibility List (HWFEED.TXT) section of this FAQ for more info on making your driver needs known. ===================================================================== 3.17. Subject : TSENG Labs ET4000 doesn't sync Question : I installed the TSENG ET4000 drivers and now my video is out of sync. Answer : You need to load the interlaced driver. Boot MS-DOS and rename the ET4000.SYS driver in \winnt\system\drivers to ET4000.BAK. Then copy ET4000I.SYS from \I386 on the CD-ROM to \winnt\system\drivers. Rename this file ET4000.SYS and reboot. Your monitor should then be able to sync correctly. ===================================================================== 3.18. Subject : Can't play audio CD's with Future Domain SCSI Controller Question : When I try to play audio CD's I get the error : CdRom0:ReadTOC failed 0xC000018 I'm using a supported CD-ROM drive and a supported Future Domain Controller. Answer : This is a known problem with the Future Domain SCSI Controller driver. Microsoft is aware of this problem and is looking into it. As soon as the driver is completed and tested, we will make it available to the public. ===================================================================== 3.19. Subject : Archive Python Tape Drive Question : I get the error : Archive Python : No drive has been detected. Make sure a drive is attached and power is on. Answer : The driver has not been installed. You will need to go into the Windows NT Setup and in the Options select Add/Remove Tape Devices. This will then allow you to install the proper driver from your CD-ROM or floppy disk install set. ===================================================================== 3.20. Subject : NEC CD-ROM slow downs Question : When my NEC CD-ROM is reader is playing audio CD's Windows NT seems to slow down dramatically. Why? Answer : We have recently discovered that the NEC Intersect CD-ROM readers have a switch which enables disconnects during accesses to the reader. This switch is normally off which means that disconnects are disabled. This means that while reads are occurring to your CD-ROM, no other devices on that SCSI bus can be accessed. Since reads from a reader can take a significant amount of time, having this switch off can noticeably degrade your systems performance. This can occur even if you are not using the CD-ROM reader. The switch is number 5 and should be set to ON. It can be found in a little box labeled SW1. ===================================================================== 4. TECHNICAL INFORMATION ===================================================================== 4.1. Subject : IBM MOST Not Supported with Windows NT Flexboot Question : How do I make Windows NT coexist on my hard drive with OS/2 2.0? Answer : As indicated in the release notes, Windows NT is not compatible with IBM's MOST utility. Microsoft does not intend to support IBM's MOST boot scheme with Windows NT's Flexboot, and has no plans to support installation on a drive with MOST installed on it. However, what you can do is install OS/2 using the dual boot capability. Boot MS-DOS, and then boot OS/2. ===================================================================== 4.2. Subject : Couldn't find NTLDR Question : When I select to start Windows NT from Flexboot it comes up with the following error: BOOT: Couldn't find NTLDR Please insert another disk Answer : In order for Flexboot to start the NTLDR must be in the root of the C Drive. If this file is missing you will get this error message. To fix this simply copy the NTLDR from the CD or the Floppies to the root of the C drive. If you are copying from the CD ROM, you will find NTLDR in the I386 directory and can copy it by going to the CD ROM Drive and entering : Copy \I386\NTLDR C:\ Or if you have a floppy install set, you will find the NTLDR on DISK 2 of the Install set as : NTLDR.$ This is the compressed version of the Windows NT Loader and must be expanded with : EXPAND NTLDR.$ C:\NTLDR. ===================================================================== 4.3. Subject : DOS Device Drivers in CONFIG.SYS Question : What are the requirements of a device driver that is loaded in the CONFIG.SYS? Answer : Device drivers loaded in CONFIG.SYS are for the use of VDMs only, and are MS-DOS device drivers, not VDDs. So only MS-DOS and Win16 programs can make use of the device drivers loaded there. Also, since VDMs don't have access to much of the physical hardware they do under MS-DOS, many device drivers won't work (and will probably cause the VDMs to hang or die on startup). ===================================================================== 4.4. Subject : The System Uses Between 70 and 130 threads. Question : My system is using a lot of threads. Is this normal? Answer : With this release of Windows NT, the Performance Monitor will show that the system running without any active applications will use somewhere between about 70 and 130 threads. This is normal for this release. The majority of these threads are system threads. The exact number observed will depend on the system options that are in effect. For example, about 16 additional threads will be used if LanmanServer and LanmanWorkstation services are active. ===================================================================== 4.5. Subject : How the LibPath environment variable works Question : Shouldn't the 'LibPath' environment variable work the same as the 'Path' environment variable? 'Path' appends the 'User environment' to the 'System environment', however 'LibPath' does not. It seems rather inconsistent. Answer : 'LibPath' is not a typical enviroment variable and does not work as it would under OS/2. It is only used by the system to scan for device drivers during startup. Windows NT uses the 'Path' environment variable to locate DLLs just like Windows 3.x does. ===================================================================== 4.6. Subject : File Compression Programs and Drivers Question : Is Windows NT compatible with my hard disk compression driver? Answer : As indicated in the release notes, you cannot place Windows NT on a partition with Stacker or any other compression or partition products. In general, Windows NT will not be able to access data on a disk that requires a driver in the CONFIG.SYS file for MS-DOS unless a similar driver has been installed for Windows NT. ===================================================================== 4.7. Subject : WOW Apps that don't work and filing a bug report Question : My Win 16 Application is not working and works on MS-DOS fine. What should I do? Answer : File a bug report using the BUGREP.TXT template from Library 3 (Problem Reports) of the WINNT forum and upload the completed form to back to the same library. The report will be passed on to Windows NT development so they can look into and attempt to correct the problem. More detailed instructions for reporting bugs can be found elsewhere in this document and a SAMPLE.TXT is available for your convenience. Be sure to include all error messages, unusual behaviors, and steps to reproduce all of the problems. The more information you include, the easier it will be to reproduce and correct any bugs in the operating system. Be sure to file a separate report for each problem that you encounter. If your problem is a low-level (and non-Setup) problem, you can use the REPRTREG.EXE program (also in Library 3) to create an ASCII dump of your registry. Generally you only want to include the HKEY_LOCAL_MACHINE part of the registry since the whole registry dump can exceed 700K. When in doubt, we recommend not including it since we can ask you for it if we need it. We are working on a better way to get this information and will hopefully have it implemented soon. ===================================================================== 4.8. Subject : /S switch is disabled from Remove Directory (RMDIR) Question : Why isn't /S working with RMDIR ? Answer : This option is disabled in the October Beta release because there were problems that came up which were to late to be fixed. When this option is used in this release, the command returns 'invalid switch -"S"'. ===================================================================== 4.9. Subject : Using fault tolerance mirroring in Windows NT Question : Why am I unable to select the "Establish Mirror" option under Disk Manager in the October Beta release of Windows NT? Answer : As mentioned in the October beta release notes, p. 25, only LAN Manager for Windows NT will support mirroring of hard drive partitions. Therefore, the option to select the "Establish Mirror" menu item will only be enabled in LAN Manager for Windows NT. ===================================================================== 4.10. Subject : OS/2 subsystem takes priority Question : Whenever I run my bound application it runs under the OS/2 subsystem and not the MS-DOS subsystem? Answer : Bound applications are designed and built so that they can be run under either OS/2 or MS-DOS. The OS2 SubSystem is not available on MIPS, therefore, bound applications will run as MS-DOS applications on MIPS. When a bound application is run under Windows NT on an 80x86, it will automatically run under the OS2 SubSystem if it is available. The OS2 SubSystem is available by default on an 80x86. In order to force bound applications to run as a MS-DOS application, it will be necessary to disable the OS2 SubSystem using REGEDIT. This is not advised unless there is a very specific need to do so. More Information: The utility REGEDIT is provided to alter the Registry Database. Note: in many cases you must be logged on as 'Administrator' to alter some of the Registry settings. In order to disable the OS2 Subsystem start REGEDIT and go to the key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\ SessionManager\SubSystems Find the value "Optional: REG_MULTI_SZ OS2 Posix" Double click on that value and remove the word "OS2". This will tell Windows NT to not load the OS/2 subsystem when it boots. Reboot your system for the change to take effect Once this is done, bound applications will run as MS-DOS applications. Running an OS/2 application will result in the following message "Cannot connect to OS2 SubSystem" WARNING: RegEdit is a very powerful utility that facilitates directly changing the Registry Database. Using RegEdit incorrectly can cause serious problems, including hard disk corruption. It may be necessary to reinstall the software to correct any problems. Microsoft does not support changes made with RegEdit. Use this tool at your own risk. ===================================================================== 4.11. Subject : ANSI ESC not supported for a command prompt Question : Why can't I get ANSI ESC codes to work with my command prompt? Answer : This is by design. The development team found this to be a performance issue. Updating the console for ANSI ESC sequences was slowing down the updates of the screen. The decision was to not slow down the console to do this. In addition, Windows NT is a GUI, not CUI (Character User Interface). Similar functionality can be provided through the console API. MS-DOS applications requiring ANSI can be used by putting a copy of ANSI.SYS from MS-DOS on the hard disk and adding the line: DEVICE=C:\ANSI.SYS in the CONFIG.SYS. ===================================================================== 4.12. Subject : Extended and Expanded memory for MS-DOS applications. Question : How do I give my MS-DOS applications Extended or Expanded memory? Answer : As with Windows 3.1, a Program Information File (PIF) can be created for applications which need resources beyond those supplied to MS-DOS applications by default. See Chapter 8 (Other Application Environments) in the October 1992 Microsoft Windows NT System Guide for more information about using PIF files. ===================================================================== 4.13. Subject : File System Conversion. Question : Can I convert my current file system to NTFS without reformatting the drive? Answer : Yes. The command-line utility, CONVERT.EXE, can be used to convert existing HPFS or FAT drives to the NTFS format. Note that no other conversions are supported at this time. It is only possible to convert FAT or HPFS to NTFS. To convert from NTFS back to FAT or HPFS, it is necessary to backup your drive, reformat it, and then restore the files back to it. Example : To convert drive "D:" from FAT to NTFS format, issue the command: "CONVERT D: /FS:NTFS" ===================================================================== 4.14. Subject : Change the default startup operating system Question : Why doesn't the change of the startup Operating System through the System applet in the Control Panel work? Answer : The settings of the Default Operating System and Timeout are stored in the BOOT.INI file. If it is READ ONLY, it can't be changed. In order to change these values, it is necessary to change this file by using ATTRIB BOOT.INI -r after booting MS-DOS. Once the READ ONLY attribute has been cleared, you can then change its values via the System tool in the Control Panel or by editing it with a text editor. ===================================================================== 4.15. Subject : Time Zone Problem Question : Why is the time zone for Anchorage at GMT -9:00? Answer : The Time Zone for Anchorage, Alaska should be GMT -9:00 and Yukon should be GMT -8:00. This would be more accurate since Anchorage is four hours different from the East Coast and one hour different from California. Yukon, Alaska should be the same as Vancouver and US Pacific Time. According to the maps in the : The World Almanac and Book of Facts 1992 The time zone for : Yukon should be GMT -8 Alaska should be GMT -9 Hawaii should be GMT -10 ===================================================================== 4.16. Subject : Disk quotas Question : Does Windows NT have the ability to set user disk quotas? Answer : The implementation of disk quotas is a non-trivial problem and we are investigating this feature for a future release of Windows NT. However, this feature will not be available in the first release. Currently, you can use the Performance Monitor to monitor quotas for an individual system and have it execute a particular action when the criteria is met. You cannot, however, monitor space on the disk on a "per user" basis. ===================================================================== 4.17. Subject : Removal of NTFS Question : How do I get rid of my NTFS partition from my C Drive? Answer : It is not possible to use the CONVERT utility from the NTFS format to the FAT or HPFS format. It is, therefore, necessary to reformat the NTFS drive. If Windows NT is not installed on the NTFS partition, then all that is necessary is to simply use the FORMAT command from a Windows NT command prompt. Windows NT will not permit you to format the drive that it is installed on. If Windows NT is installed on the NTFS partition, and you wish to reformat the drive, you will need to the following steps in order to reformat it. 1) Start the Windows NT Installation procedure 2) Choose "Custom Installation" 3) When Windows NT Setup asks you to select the partition where you would like to install, highlight the NTFS drive and press "P" to delete the partition. 4) Either continue from here using the setup program to recreate and format the partition -or- Simply exit the setup program and use FDISK and FORMAT to complete the process. ===================================================================== 4.18. Subject : CHKDSK /F on an NTFS drive Question : Why won't Windows NT let me run "CHKDSK /F" on my NTFS formatted drive? Answer : There are two basic reasons that this might happen. 1) If you see the message: "Cannot lock the current drive." you should simply make another drive current. For example, if you are trying to run CHKDSK /F for the D: drive, make C: the current drive by typing "C: <ENTER>" before issuing the CHKDSK command. 2) If you see the message: "Cannot lock the drive for single user." this indicates that there are open files on the drive you are attempting to check. If Windows NT is not installed to the drive in question, simply be sure that all applications that might have files open on the drive are closed. If you have a pagefile on the drive, that too must be moved by using the options in the Control Panel under Virtual Memory. You should then be able to run CHKDSK with the /F option. If Windows NT IS installed to the NTFS drive for which you are trying to run CHKDSK /F, then it is necessary to make a change in the Registry as follows: HKEY_LOCAL_MACHINE->SYSTEM->CurrentControlSet->Session Manager, change the BootExecute string from : "autocheck autochk *" to "autocheck autochk /p *" This will force Windows NT to automatically run a CHKDSK /F at every boot until the string is returned to its original value. Then shut down and restart the system. Note that it should rarely be necessary to use this procedure. The normal autocheck routine will automatically run CHKDSK /F any time a "dirty" volume is encountered at system boot time. Also note that it is normal for CHKDSK to report "consistency errors" on an NTFS drive containing the pagefile. As long as no specific files are listed as being damaged and no other errors are detected, the volume will be marked "clean" and there is usually no need to force a CHKDSK /F. WARNING: RegEdit is a very powerful utility that facilitates directly changing the Registry Database. Using RegEdit incorrectly can cause serious problems, including hard disk corruption. It may be necessary to reinstall the software to correct any problems. Microsoft does not support changes made with RegEdit. Use this tool at your own risk. ===================================================================== 4.19. Subject : MS-DOS Device Drivers in CONFIG.SYS Question : How do I load Device Drivers in CONFIG.SYS for my MS-DOS applications? What can and can't I use in CONFIG.SYS ? From what I am told, hardware specific drivers won't work. What's left? Answer : You can only use device drivers in CONFIG.SYS that touch parts of the system that are emulated by the VDM (Virtual DOS Machine) code. This is why ANSI.SYS will work (because the display is an emulated device) but ASPI drivers won't (since that hardware is not emulated.) If you have some software that requires a device driver, it is quite possible that the people who wrote that device driver will need to write a VDD (Virtual Device Driver) for that driver, and possibly a Windows NT Device Driver to support that VDD. The information required to write these drivers can be found in the Windows NT DDK. ===================================================================== 5. NETWORK INFORMATION ===================================================================== 5.1. Subject : TCP/IP Support Question : Does the October Beta release of Windows NT has complete TCP/IP support? Answer : The October Beta Release of Windows NT contains full TCP/IP support for Windows NT. The machines running Windows NT with the TCP/IP protocol stack will be able to communicate with LAN Manager 2.x Servers and Workstations. Windows NT will also have an extensive set of TCP/IP utilities including Telnet, ftp, rcp, rsh, etc. Third party vendors have shown interest in providing the host software for the TCP/IP utilities. ===================================================================== 5.2. Subject : Replication Question : I noticed on Windows NT machines, the replicator service only allows you to import files/directories. Does that mean to actually use replication (which requires some server exporting data) a LAN Manager for Windows NT or LAN Manager for OS/2 server will be required? Answer : Yes. You must have a LAN Manager for Windows NT system to use the file replicator. Clarification: Here are the rules involving Windows NT systems and replication: - You must have a LAN Manager for Windows NT system to EXPORT with the file replicator. - The WinNT systems can IMPORT from a LAN Manager for Windows NT exporter. - OS/2 Lanman systems can IMPORT from a LAN Manager for Windows NT exporter. - LAN Manager for Windows NT systems can also IMPORT from other LAN Manager for Windows NT systems (or even the same machine). OS/2 LM (EXPORT) >> NT (IMPORT) is not supported ===================================================================== 5.3. Subject : Network fails to start Question : After installing Windows NT, my network fails to come up. What is wrong? Answer : Please see page 30 of the Release Notes for October 92 Beta release of Windows NT. - Check for interrupt conflicts - Check for memory conflicts - Check for duplicate machine name - Check the proper configuration settings for your appropriate network card. If you are still having problems, contact Microsoft Product Support Services using Section 3 (Windows NT Setup) of the WINNT forum on CompuServe as described in Microsoft Windows NT October 1992 Beta Program Support Notes. ===================================================================== 5.4. Subject : Using TELNET in Windows NT Question : How do you use Telnet in Windows NT? Answer : Telnet in Windows NT has been implemented as a Windows NT Service. You can start the Telnet service by typing NET START TELNET on command line or you can start it from the Control Panel and Services option. To use telnet, take the following steps. 1. Start Terminal from command line or the Accessories group. 2. Select Communications options in the Settings menu. 3. Set the Connector to be TELNET and click on OK. 4. You will get the telnet command prompt. Now you can use the Telnet commands to connect to your favorite host. ===================================================================== 5.5. Subject : Differences in LAN Manager Domains and Domain option in Windows NT. Question : I have specified my LAN Manager 2.x domain name in the Domain entry of Windows NT network setup. It gives me an error. Why? Answer : The Domain entry in Windows NT network setup refers to the LAN Manager for Windows NT domain. In order to participate in the LAN Manager 2.x domain, you need to specify the LAN Manager 2.x domain as the workgroup name for Windows NT. After you have specified the workgroup name to be the LAN Manager 2.x domain, you will be able to see your LAN Manager 2.x servers from FileManager and by typing NET VIEW on the command line. Note: LAN Manager for Windows NT is a separate product which provides additional enterprise-wide domain-based network management capabilities, advanced fault-tolerance, etc. ===================================================================== 5.6. Subject : Workstation and Server files missing Question : When I installed Windows NT, I did not install a network card. Now that I have one and have installed it with the Windows NT Setup program, the workstation fails to start. What am I doing wrong? Answer : When a new network card is installed through the control panel with the network applet, it copies all the necessary files from the setup CD-ROM or floppy diskettes. However, it does not install the workstation and server files. This complex problem would involve a number of "by hand" changes to the registry so a solution is far to complex to describe. The best solution is to install Windows NT with a network card, even if one is not currently in the machine at that time. Then it can be removed the card and reinstall the correct card. This problem has been identified and will be addressed in the next release of Windows NT. ===================================================================== 5.7. Subject : Upgrading to LAN Manager for Windows NT Question : Will there be a LAN Manager for Windows NT upgrade set so that I can upgrade my Windows NT machine to LAN Manager for Windows NT? Answer : Although we agree that this is important, it has been decided that other priorities (such as LM 2.1 and Windows 3.x upgradability) should be dealt with first. We feel that we have made the best tradeoff and this feature is definitely on the list for the future after Windows NT is released. ===================================================================== 5.8. Subject : WORKGROUP or DOMAIN Question : What is the difference between a DOMAIN and a WORKGROUP in Windows NT? Answer : The primary difference between a WORKGROUP and a DOMAIN is in where the users' accounts are maintained and which machine handles the validation of accounts. In a WORKGROUP, the account information is maintained locally on each workstation. In a DOMAIN, the user's account information is maintained on a primary server or replicated across a group of servers (domain controllers) for the DOMAIN and the permissions for that user are consistent across the entire DOMAIN. LAN Manager 2.x servers may also be members of a Windows NT domain. ===================================================================== 6. COMMON ERROR MESSAGES ===================================================================== 6.1. Subject : Error 0000001E Question : I am getting error 0001E. What do I do? Answer : Unknown at this time. Microsoft is looking into the cause of this error and will post it here when it is resolved. ===================================================================== 6.2. Subject : NTVDM error when running MS-DOS or WIN3.1 Apps Question : Why can't I run MS-DOS or Win 3.x apps? Error received : Insufficient memory or Disk Error in NTVDM Answer : There are a few possible causes to this problem: a) Increase the swap file size to the 20MB minimum. b) Make certain that the video card is on the hardware compatibility list and if not run in vanilla VGA. c) Something else not identified at this point ===================================================================== 6.3. Subject : Error 0x00000069 or Error 0x00000067 Question : I get Error 0x00000069. What do I do? Answer : This is a initialization error, which happens when Windows NT tries to talk with the HD controller. It can be caused by any number of things. Things to try: * If the card allows, slow down the DMA transfer rate. * Make sure both ends of the SCSI bus are terminated. * Make sure there are no IRQ, or memory address conflicts. * Make sure you're aren't using a faulty or un-supported driver i.e. the FD 1680 SCSI controller is supported, but there is a problem with that driver which will be fixed and posted on CompuServe in WINNT, Library 2. A list of supported devices can be found in WINNT, Library 1, 1092HW.TXT. * Make sure that NTDETECT.COM is in the root of the booting partition. Missing files from Windows NT can cause an Error 69. ===================================================================== 6.4. Subject : Fatal System Error 0x0000000A Question : What do I do about : Fatal system error 0x0000000A IRQL expected to be less than or equal Answer : This usually indicates that you have changed the interrupt settings on a card and it now disagrees with what's indicated as the interrupt setting that you entered during setup. It is possible that you have installed a new card since you installed Windows NT or, that you possibly have an interrupt conflict with some other piece of hardware in your system. ===================================================================== 6.5. Subject : System Error F002 Question : I get System Error F002. Answer : If you receive a System error F002,this probably means that your hardware is faulty; for example, you may be experiencing a memory failure. This error is generally caused by a hardware incompatibility in the machine which may be caused by one of the following: 1) Memory parity errors 2) some card asserts an I/O channel check on the bus,usually VGA or net cards 3) math coprocessor had an error If this occurs, run the manufacturer's diagnostic procedure. ===================================================================== 6.6. Subject : Setup fails with a SCSI read request error Question : Why do I get the following error when installing NT: "SCSI read request failed Arc status 8 Srb status 0084" Answer : There are possible FAT or other file system problems on the drive which autocheck is not handling. Please run a diagnostic check on the file system such as chkdsk or other 3rd party application. It is possible that there is a partition problem or cross linked files on the disk. Try correcting these and then rerun setup. ===================================================================== 6.7. Subject : Error X00000022 - Generic Bugcheck Question : I get the error X00000022 - Generic Bugcheck. What should I do? Answer : Unknown at this time. Microsoft is looking into the cause of this error and will post it here when it is resolved. ===================================================================== 6.8. Subject : Fatal Kernel Error 006E or 0071. Question : Why do I receive the following error messages when booting from text to GUI setup? Messages are: BOOT: I/O Error reading disk Please insert another disk -OR- Fatal Kernel Error 0000006E Fatal Kernel Error 00000071 -OR- The system freezes at the blue screen with no error message. Answer : If you are on a turbo system or any multi speed CPU system please turn off the turbo or operate at the lowest CPU setting after the text portion of setup has copied the files to the hard drive until the GUI portion of setup resumes copying files to the hard drive. It is important that if this error occurs that you fill in a bug report template including full machine configuration information so that development can fix this problem as soon as possible. The template can be found in WINNT, Library 3, as BUGREP.TXT. There is a sample report to use as a guideline as well (SAMPLE.TXT). Upload the completed report to Library 3 and it will be passed on to development for review. ===================================================================== 6.9. Subject : Install keeps asking for DISK 6 Question : During the Windows NT installation, Setup continually asks for DISK 6 from the Graphical setup. What do I do? Answer : Microsoft is aware of this problem and currently is looking into it. As soon as we isolate the problem and test it, a fix will be available for download from CompuServe. At this point, we believe it is not a problem with SETUP but a problem with the driver for the floppy drive. We will try to make a fix available when it has been completed and tested.
