GRAPHICS ADAPTER DEVICE DRIVERS (GRADD) _______________________________________ GRADD is an IBM OS/2* device driver architecture that makes it easier to support new graphics hardware as it becomes available. Enhanced PM applications performance can be realized when using accelerated GRADD drivers. The GRADD device drivers provide seamless support for accelerated and unaccelerated display graphics and advanced color depth and resolutions. They conform to the OS/2 32-bit flat memory model and are designed to function as 32-bit Presentation Manager* graphics display drivers under the OS/2 32-bit graphics engine. Several new and updated GRADD drivers are contained in this package, including the SciTech Display Doctor/se** GRADD. DRIVERS INCLUDED ________________ The following accelerated GRADD drivers is included: * SciTech Display Doctor GRADD (SDDGRADD) Which provides both accelerated and unaccelerated support for nearly all common VGA and SVGA adapters (see list below). SciTech Display Doctor/se** automatically detects your graphics adapter each time during boot up. Also included are IBM generic VGA and SVGA support. * Video Graphics Array GRADD (VGAGRADD) * Generic VESA Unaccelerated GRADD (GENGRADD) These additional drivers are provided as backup drivers or for comparison, in case you encounter problems with the SciTech Display Doctor/se** GRADD. GENGRADD may provide UNACCELERATED support for display graphics at enhanced resolutions and colors depths. GENGRADD will work with most adapters that include a VESA compliant BIOS; and the performance, which will vary depending on system configuration, will not be as good as an accelerated driver. Similar legacy (VESA VBE) support is built into the SciTech Display Doctor/se** GRADD, and will be used when the SciTech Display Doctor/se** GRADD has no accelerated support for your graphics adapter. ABOUT SCITECH DISPLAY DOCTOR FOR OS/2 _____________________________________ SciTech Display Doctor/se** for OS/2 brings SciTech's proven universal device driver technologies to the OS/2 operating system. SciTech Display Doctor for OS/2 incorporates the SciTech Nucleus Graphics Architecture, which is a cross platform device driver technology enabling the use of the same device drivers in all versions of SciTech Display Doctor. Sharing the drivers between platforms improves the quality and performance of device drivers for all supported operating systems.

Please note that this list refers to the actual chips being used, not the laptop brand or model itself. Thus you will not see any products from Gateway or Dell on the list, but their products are supported because they use NeoMagic, ATI, Cirrus etc. chips. . ATI 3D Rage LT Pro, Rage Mobility . Chips & Technologies 65550, 65554, 65555, 69000 . Cirrus Logic CL-GD7555 LCD . NeoMagic MagicGraph 128, MagicGraph 128XD, MagicGraph 256AV . S3 Virge/MX . Trident Cyber9385 LCD, Cyber9397 LCD . VESA VBE 1.2, VBE 2.0, VBE 3.0 SUPPORTED RESOLUTIONS _____________________ Supported resolutions and color depths are adapter dependent and will vary depending on the amount of graphics memory and the adapter implementation. COMPATIBILITY _____________ These graphics device drivers are currently compatible with: All versions of OS/2 3.0 with fixpak level 35 or later All versions of OS/2 4.0 with fixpak level 5 or later All versions of OS/2 Warp Server for e-business The SETUP installation command rejects installations on unacceptable OS/2 versions or fixpak levels. Also, after installing these graphics drivers, if you later wish to uninstall any required Fixpak to a Fixpak level before Fixpak 5 (OS/2 4.0) or Fixpak 35 (OS/2 3.0), you should first restore your computer to VGA to remove the SciTech Display Doctor/se** GRADD BBS drivers. Other than the use of English messages, the SBCS drivers installed for SBCS languages not in the SET LANG= list in the section entitled "Extraction" above are correctly functional for the chosen language. FUNCTIONAL RESTRICTIONS _______________________ Current known restrictions include the following: 1) SciTech Display Doctor/se** generally only supports PCI and AGP graphics adapters, and does not support ISA, VLB and Microchannel. The only exception is for laptop chipsets that are on a non-PCI local bus, or early motherboard integrated chipsets such as the early MediaGX family. 2) The SciTech Display Doctor/se** GRADD drivers, do *NOT* require a chipset specific SVGADATA.PMI file, but instead have a single PMI file implemented via a DLL. Hence when running SDDGRADD do *NOT* use the SVGA ON INIT command to create an SVGADATA.PMI file. 3) The IBM GENGRADD drivers, require VESA** compliant video BIOS (Version 1.2 or greater) or an appropriate SVGADATA.PMI file to provide generic unaccelerated VESA support. For older non-VESA adapters with SVGA PM driver support from IBM, GENGRADD may often be used as an alternative SVGA driver set by following the GRADD Graphics BBS drivers SETUP installation command with the command "SVGA ON INIT" from an OS/2 or DOS Full Screen prompt to create an SVGADATA.PMI file, before rebooting to use the GENGRADD drivers. 4) If you enable the HPFS386 Local Security feature, you must make sure that: - The x:\os2\drivers\nucleus directory is always readable. - The x:\os2\drivers\nucleus\config subtree has read/write/create access for all users. Where "x:" is your OS/2 boot drive. Failure to do this will cause your system to not boot properly unless the administrator is logged on. 5) Any adapter with less than 512KB of memory cannot be supported by SciTech Display Doctor. You can find future fixes and updates for the SciTech Display Doctor/se** GRADD and other graphics device drivers via the internet at: http://service.software.ibm.com/os2ddpak/index.htm APAR FIXES INCLUDED IN THIS DRIVER __________________________________ Some fixed APARs may not be listed. If you received this driver through the IBM OS/2 support channel and your requested APAR is not listed, please install the driver, as your requested APAR is included. INSTALLATION......................................................... PRELIMINARY STEPS _________________ The following steps prepare your computer before installing the SciTech Display Doctor/se** GRADD device drivers: 1. Other applications, particularly WIN-OS/2 applications, should be closed so that the device driver installation can replace the driver files which an open application might have locked as read only. 2. If you previously installed an SVGA driver, return to VGA resolution using the procedures in the section of this README entitled "Setting Your Display to VGA Mode". EXTRACTION __________ To set up the SciTech Display Doctor** 7.0 for OS/2 IBM Special Edition GRADD BBS driver installation directory, do the following: 1. Open an OS/2 full-screen or OS/2 window session. 2. Before running the SDDGRADD*.EXE self extracting zip file (the exact name depends on the release build number), change the current directory to the "installation directory" in which you wish to store the SciTech Display Doctor GRADD BBS driver installation files. It should be something *other* than x:\sdd, where "x:" is your boot drive. We suggest C:\BBS\SDD. At the OS/2 command prompt, type the following commands: C: MD C:\BBS MD C:\BBS\SDD CD C:\BBS\SDD 3. Use the "-DIR" and "-OVER" options on the SDDGRADD*.EXE self extracting zip file to create the installation directory tree. You may wish to copy the SDDGRADD*.EXE self extracting zip file to the installation directory first. Then at the OS/2 command prompt, type the following command: SDDGRADD* -DIR -OVER 4. Use SET LANG= to set the correct language. The language may already be correctly set in your CONFIG.SYS. If not, then at the OS/2 command prompt, type one of these SET LANG= commands to choose your language: SET LANG=ar_AA for Arabic (English with Arabic graphics formatting) SET LANG=pt_BR for Brazil SET LANG=zh_CN for Simplified Chinese SET LANG=de_DE for Germany SET LANG=da_DK for Denmark SET LANG=es_ES for Spain SET LANG=el_GR for Greece (English with Greek graphics formatting) SET LANG=fi_FI for Finland SET LANG=fr_FR for France SET LANG=iw_IL for Israel (English with Hebrew graphics formatting) SET LANG=it_IT for Italy SET LANG=ja_JP for Japan SET LANG=ko_KR for Korea SET LANG=nl_NL for Netherlands SET LANG=no_NO for Norway SET LANG=sv_SE for Sweden SET LANG=zh_TW for Taiwan SET LANG=en_US for English (default) Each language has its own copy of this README.TXT file, which may be translated from English, as well as other language dependent files. 5. The SETUP command in the installation directory may then be used to install the proper language dependent files and configuration information from the install directory onto your boot drive. Running SETUP without any options will give brief syntactic help about the SETUP command (described later in detail in this README file) in your chosen or default language. To see this help, at the OS/2 command prompt, type the following command: SETUP COPYING TO DISKETTES (OPTIONAL) _______________________________ Once extracted to an installation directory tree, you may place the SciTech Display Doctor/se** GRADD driver installation files on diskettes for backup or transportation purposes using the OS/2 BACKUP command: 1. Open an OS/2 full-screen or OS/2 window session. 2. Type "BACKUP C:\BBS\SDD A: /S" and press the Enter key. 3. Label and insert as many pre-formatted diskettes as required. 4. You can use HELP BACKUP to get more information about the BACKUP command. To restore the same diskettes to the same or a different computer: 1. Open an OS/2 full-screen or OS/2 window session. 2. Type "RESTORE A: C:\BBS\SDD /N /S" and press the Enter key. 3. Insert previously backed up diskettes as required. 4. You can use HELP RESTORE to get more information about the RESTORE command. IBM and SciTech have made no provision for installing these drivers directly from diskettes. SETTING YOUR DISPLAY TO VGA MODE ________________________________ If your display is in sync and you otherwise have a usable Desktop, we recommend that you use Selective Install to set your display to VGA mode. Otherwise, use the following procedures to return to VGA mode. 1. Turn on your computer. If your computer is already on, shutdown or press Ctrl+Alt+Del to restart it. 2. When a small white box appears in the upper left-hand corner of your screen, press Alt+F1. 3. When the Recovery Choices screen appears, press function key F3 or the letter "V" depending on the operating system version. 4. Run Selective Install to change the Windows drivers. Once the computer has booted, your display adapter is restored and can work in VGA mode. If you want to install a new display adapter or graphics device driver, refer to the chapter entitled "Video Procedures" in the User's Guide to OS/2 Warp. ATTENDED INSTALLATION _____________________ To do an attended install of the SciTech Display Doctor/se** GRADD Drivers from the self extracting zip file installation directory, do the following: 1. Open an OS/2 full-screen or OS/2 window session. 2. Before running the extracted SETUP.CMD file, use SET LANG= to set the correct language. The language may already be correctly set in your CONFIG.SYS. The section of this README entitled "Extraction" gives examples. 3. At the OS/2 command prompt, type the following command to copy all the required files to the OS/2 boot drive: SETUP xxx [] [] [/u] Where: xxx is one of: "GEN" - Generic VESA Unaccelerated GRADD "SDD" - SciTech Display Doctor GRADD "VGA" - Video Graphics Array (VGA) GRADD for SETUP is required if SETUP is not in the current directory. [] parameter is optional (required if next parameter specified) and is the installation directory. [] is optional and is the drive where OS/2 is installed. [/u] is optional and indicates an unattended install such as for CID installations. A CID response file is not required. Then press Enter. 4. When prompted to do so, shutdown, and then restart your computer. NOTES: 1) During the installation of this driver, DISPLAY.LOG and DSPINSTL.LOG files are created or appended to in the OS2\INSTALL directory. These files identify the OS/2 system files that were updated and indicate whether the installation was successful and reasons for failure. The contents of these files might be useful if you need to report an installation problem to IBM. 2) You may be prompted about whether you want to overlay certain files where the target file is newer than the source file. In general, you should answer YES to all the prompts unless you have previously experienced specific problems with the driver and are reinstalling it. 5. After the computer reboots, the desktop should be in the 640x480x256 display mode. Do the following to configure correctly for your current display and choose an appropriate resolution and refresh rate: a. Open the OS/2 System folder. b. Open the System Setup folder. c. Open the System object. d. When the Settings notebook appears, select the Screen tab. Then go to Screen Page 2. e. The listed monitor should be 'SciTech Display Doctor' which will allow you to use all the resolutions and color depths that the SciTech Display Doctor drivers support. f. Open the SciTech Display Doctor/se 7.0 folder. g. Open the Monitor Utility. h. Select your monitor (see the next section). The current version requires you to shutdown and restart your computer at this point in order to have your monitor selection affect the list of resolutions and refresh rates available. However, if you know your monitor's limits, you may just continue, but limit your resolution and refresh rate selections accordingly. i. Return to the System Properties Screen Page 1 and select a resolution and refresh rate. Depending your adapter and display, refresh rates may not be selectable. j. Close the Settings notebook. k. Shutdown and restart your computer. 6. When you have completed the installation, all the SciTech Display Doctor command line utilities will be located in the x:\sdd directory, where "x:" is your OS/2 boot drive. Most will also be found in the SciTech Display Doctor/se 7.0 folder on your desktop. INSTALLATION IN A CID ENVIRONMENT _______________________________ NOTES: 1. Create a directory on the server (e.g. X:\BBS\SDD) and extract the installation files from the self extracting SDDGRADD*.EXE file to the X:\BBS\SDD installation directory as described under the section entitled "Extraction". 2. You must have OS/2 successfully installed on the client using the CID (Configuration Installation Distribution) method. 3. To configure display selection, resolution and refresh rate, refer to the file "README.CFG" in this package. To install a device driver using CID, use the following information to modify your LCU command file. The example below installs the SciTech Display Doctor/se** GRADD (SDDGRADD). NOTE: The following information is meant as a guide. Your LCU command file might be different. /*****************************************************/ /* LCU PRODUCT DATA SECTION */ /*****************************************************/ . . . x.graddvideo = 15 x.15.name='SciTech Display Doctor GRADD Video' x.15.statevar = 'CAS_' || x.15.name x.15.instprog = 'x:\bbs\sdd\setup.cmd', ' sdd', ' x:\bbs\sdd ' || bootdrive, ' /u' x.15.rspdir = '' x.15.default = '' /*****************************************************/ /* NUMBER OF PROGRAMS SET UP IN THE */ /* PRODUCT DATA SECTION */ /*****************************************************/ NUM_INSTALL_PROGS = 15 /*****************************************************/ /* INSTALLATION SECTION */ /*****************************************************/ . . . when OVERALL_STATE = 2 then do if RunInstall(x.graddvideo) == BAD_RC then exit Call CheckBoot end . . . /******************************************************/ /* ROUTINE SECTION */ /* The following information should already exist in */ /* the LCU command file. */ /******************************************************/ . . . RebootAndGotoState: parse arg new_state, other rc2 = SetState(new_state, 'RebootAndGotoState', 1) /* Set the state */ /* to go to in */ /* OVERALL_STATE */ Call SaveStates /* Save the environment vars */ Call Reboot /* Reboot the computer */ return . . . /*****************************************************/ /* END OF LCU INFORMATION TO BE ADDED */ /*****************************************************/ RESTORING YOUR SYSTEM IN CASE OF FAILURE ________________________________________ If SciTech Display Doctor does not correctly boot on your system, you can easily switch back to the GENGRADD drivers to boot your system to a workable state again. To revert to GENGRADD, do the following: 1. Boot to an Alt-F1/F2 command prompt mode. 2. Edit CONFIG.SYS file and change the line C1=SDDGRADD to C1=GENGRADD,SBFILTER Remove the line "DEVICE=x:\OS2\SDDHELP.SYS". Remove the line "SET VCFG_NO_DDC=TRUE". 3. Delete the x:\OS2\SVGADATA.PMI file. 4. Shutdown and reboot your system. If that fails you will need to revert to VGA mode and reinstall your prior display drivers. REMOVING SCITECH DISPLAY DOCTOR _______________________________ SciTech has included an uninstall program you can use to completely remove SciTech Display Doctor and all its components from your system. To remove SciTech Display Doctor, simply run the x:\SDD\UNINSTAL.EXE program, where x: is the OS/2 boot drive. This will remove all files, and revert your system to VGA mode. From there simply reinstall your original display drivers or GENGRADD or VGAGRADD. ADVANCED OPTIONS........................................................... GAMON MONITOR SELECTION PROGRAM _______________________________ If you have a plug and play monitor, SciTech Display Doctor will automatically detect its capabilities. If your monitor is not detected, you can manually configure it using the GAMON utility. This is a simple program to allow you to select a monitor that is attached to your graphics card. Selecting a monitor will filter the available display modes and refresh rates depending on the capabilities of your attached monitor. If you use the GUI version selected from the SciTech Display Doctor/se 7.0 folder, you should leave off "gamon" command name at the start of the following command examples. If you wish to use the command line version of this or other SciTech programs, you may wish to add the path "x:\sdd" to your OS/2 command search path, where "x:" is your OS/2 boot drive. To select a monitor you must know the manufacturer and model name for your monitor. To list all available manufacturers, use the following command: gamon mfr This will produce a rather long list, so you can narrow the list by entering the start of the manufacturer name like and list all monitors that manufacturer makes: gamon model nec which will list all 'NEC Technologies' monitors. Once you have found your monitor, you can select it by entering the partial manufacturer name and a partial model name like so: gamon select nec xp21 which will select the 'NEC Technologies' 'NEC XP21' monitor. Of course this selection program is a bit archaic at the moment, and our SciTech Display Doctor GUI control center will allow you to select a monitor (and adjust the properties) much more conveniently in the final release. GAREPORT HARDWARE REPORT PROGRAM ________________________________ This is a simple program which will load the SciTech Nucleus display driver for your hardware, and report the graphics hardware configuration. GACTRL CONFIGURATION PROGRAM ____________________________ This program allows you to perform compatibility testing on the Nucleus device drivers, including testing the graphics modes, stereo modes (which won't work under OS/2 yet unless you have hardware stereo), DPMS Power Management and DDC communications. One of the other useful things that this program can do is allow you to adjust the centering and refresh rate control for all available display modes (including text modes for OS/2 command prompts!). Use the 'Centering and Refresh' menu item to change the refresh rate and centering values for individual display modes, or the 'Global Refresh Rate' menu item to set all display modes to a preferred refresh rate. Of course the centering and refresh control will eventually be controlled by our SciTech Display Doctor GUI control center, but that component is still under development and not ready for testing. NOTE: Changing the global refresh rate *also* changes the refresh rate for VGA text modes to your preferred value. You may want to reset the text modes back to 70Hz manually if the refresh rate controlled text modes cause problems. GAOPTION OPTIONS SELECTION PROGRAM __________________________________ This is a simple command line program to allow you to override some of the useful options for the SciTech Nucleus drivers. To see the current list of options and settings, use the following command: gaoption show This will show all the options for the current device. Some of the more useful options are explained below: gaoption accel [none | basic | most | full] This option controls what hardware acceleration features are used by the drivers. By default full hardware accleration is enabled. If you have problems with the mouse cursor, try 'most', which will disable hardware acceleration of the mouse cursor. The 'basic' setting will allow for basic acceleration features and is useful if you have problems with line drawing or text. The 'none' option turns off all hardware acceleration in the driver. gaoption vbe [on | off] This opton controls whether the VBE/Core fallback driver is used by default, or whether the native hardware accelerated drivers are used. By default this option is off, but you may want to enable this option if the native driver has problems on your system. gaoption prefer32 [on | off] This option controls whether you would prefer 32-bit display modes over 24-bit display modes to show up in the list of available display modes for the SDDGRADD driver. The deault is to choose 32-bit modes in preference to 24-bit modes if the mode exists at both color depths, and both color depths are fully accelerated. Otherwise the highest performance mode is always chosen. gaoption nowcomb [on | off] This option controls whether the Nucleus drivers will attempt to enable write combining on your system for faster system memory to video memory transfers. By default write combining will always be used where possible, but if this is causing problems you may with to try using this option to disable write combining support. The most likely scenario would be for a new processor that has not yet been fully QA tested. NOTE: You will need to reboot before any of the options will take effect for the SDDGRADD display drivers. SUPPORT................................................................... SciTech Display Doctor/se for OS/2 is distributed by IBM and is supported through normal IBM support channels. Please note that SciTech Software does not provide support for SciTech Display Doctor/se for OS/2.
