- Using Disk Manager 5.10 and Windows 3.1
- ----------------------------------------------------------------------------
-
- COMPATIBILITY WITH SMARTDRV 4.0
-
- Microsoft's new SmartDrv disk cache, version 4.0, is compatible with all
- versions of Disk Manager software, however, incompatibilities still exist
- with SmartDrv's double buffer support for SCSI host adapters. Although you
- will be able to use SmartDrv, you may need to modify your CONFIG.SYS file
- for things to work properly. Note that the SmartDrv cache is now installed
- by a separate command line in your AUTOEXEC.BAT file and that the changes to
- your CONFIG.SYS file suggested below affect only the SmartDrv double buffer,
- not the cache itself.
-
- Select the option below that matches your system's configuration and edit
- your CONFIG.SYS file following the instructions for that configuration.
-
- 1) System with no SCSI host adapter.
-
- If you do not have a SCSI host adapter, then you do not need SmartDrv's
- double buffer. To be compatible with Disk Manager software's support
- for drives over 1024 cylinders and large partitions under DOS 3.30 and
- prior, you must remove the SmartDrv device statement,
- DEVICE=C:\WINDOWS\SMARTDRV.EXE /DOUBLE_BUFFER, from your CONFIG.SYS
- file, if it is present.
-
- 2) System with SCSI host adapter but no drives with more than 1024
- cylinders.
-
- If you have a SCSI host adapter, but do not have any non-SCSI drives
- with more than 1024 cylinders, you must install SmartDrv's double
- buffer. To be compatible with Disk Manager software's support for
- partitions larger than 32MB under DOS 3.30 and prior, you must edit the
- SmartDrv device statement to include a PLUS SIGN at the end of the
- line. The line should appear as follows, and you should be sure there
- is no space before the PLUS SIGN.
-
- DEVICE=C:\WINDOWS\SMARTDRV.EXE /DOUBLE_BUFFER+
-
- 3) System with SCSI host adapter and drives with more than 1024 cylinders.
-
- If you have a SCSI host adapter and a non-SCSI drive with more than
- 1024 cylinders, you must remove the SmartDrv device statement from your
- CONFIG.SYS file. Though this will allow your system to run, you will
- not be able to run Microsoft Windows in 386 enhanced mode. Ontrack
- Technical Support (612)937-2121 can provide suggestions on
- reconfiguring your system so you can use Smartdrv's double buffer and
- Windows 386 enhanced mode.
-
-
- COMPATIBILITY WITH WINDOWS 3.1 PERMANENT SWAPFILE
-
- Enhancements have been made to Disk Manager hard disk installation software
- version 5.10 that will allow the use of Microsoft Windows 3.1 permanent
- swapfiles. However, there are a few situations involving Disk Manager
- software that will prevent you from creating a permanent swapfile, most of
- which can be resolved. These situations are listed below along with
- suggestions for resolving them.
-
- 1) Head or sector-per-track mismatch. (If you have an IDE drive skip to #2)
-
- If the number of heads and sectors-per-track specified by your CMOS
- drive type entry does not match the actual number of heads and sectors
- per track of your drive, your configuration prevents the use of a
- permanent swapfile. Resolving this conflict will require that you
- reinstall your drive and will likely result in lost disk space. If you
- must use a permanent swapfile, Ontrack Technical Support (612-937-2121)
- can provide suggestions on reconfiguring your system to allow it.
-
- 2) Large partitions under DOS version 3.30 and earlier.
-
- If you are using DOS 3.30 or below and have a partition larger than
- 32MB, you can not use a permanent swapfile. You can make your system
- permanent swapfile compatible by upgrading to DOS 4.0 or above and
- reinstalling your system, or by reinstalling under your current DOS
- version and making all partitions 32MB or less.
-
- 3) Drives with more than 1024 cylinders.
-
- Permanent swapfiles may only be accessed by Windows if they are created
- within the first 1024 cylinders of your drive. Take care to create
- your swapfile on a partition under 1024 cylinders, otherwise, Windows
- will issue a corrupt swapfile error when started. It is best to create
- your permanent swapfile on a DOS partition (such as drive C:) to ensure
- that it is under 1024 cylinders. If you have a drive with more than
- 1024 cylinders, you need to manually enable permanent swapfile support.
- Modify the DMDRVR device statement in your CONFIG.SYS file to include a
- /P as shown below.
-
- DEVICE=C:\DMDRVR.BIN /P
-
- If you have problems with corrupt swapfile errors when using the /P option,
- it is likely that your permanent swapfile is not under 1024 cylinders.
- Contact Ontrack Technical Support, (612)937-2121, for additional assistance.
-
- If none of the situations listed above apply to your system, it will
- automatically be made compatible Windows 3.1 permanent swapfiles the first
- time you boot with the new Disk Manager software installed.
-
- If, after installing the new Disk Manager software and following the
- instructions above, you are still unable to create a permanent swapfile,
- there may be something other than Disk Manager software preventing it.
- Ontrack Technical Support, (612)937-2121, can assist you in identifying
- other conflicts.
-
- A more detailed, technical description of the issues involving Disk Manager
- software version 5.10, SmartDrv version 4.0, and Windows 3.1 permanent
- swapfiles is available for download from Ontrack's BBS (612)937-0860. This
- document is very technical in nature and is intended for advanced hardware
- and software engineers. Very few users require this level of information,
- therefore, Ontrack Technical Support will not provide detailed support
- regarding its contents.
