Unofficial Drivers & Utilities

Community-supplied drivers extend the capabilities of the XGA subsystem beyond what's possible with the official IBM drivers. These improvements include support for newer operating systems, higher resolutions, and greater color depths.

XGAUTIL

xgautil.exe XGA/XGA2 Utilities (P70.exe & P75.EXE) (zipped image)

P70.EXE

This disables the P70 plasma display and places an installed XGA adapter into VGA mode if the XGA card has a display connected. The utility will not switch to the XGA card if the system board XGA has a display connected.

/u (undo) return to the plasma display.
/h or /? for help.

P75.EXE

This selects the P75 plasma display as the primary VGA display and disables the VGA output on the Micro Channel installed XGA adapter.

/u (undo) return VGA output to the XGA adapter.
/h or the /? option for help.

XGAPATCH

xgapatch.com XGA Patch files for 9533 Starter Disk

Copy the files XGAF1NI.DGS and 8FDAM.DG$ to your backup copy of the 9533 Starter Diskette, overwriting the files of the same name. Use this modified Starter Diskette to run diagnostics on your machine.

XGAF1NI.DGS - XGA Diagnostic file
8FDAM.DG$ - DMQS Monitor Information

XGAOPT

xgaopt.zip XGA/XGA2 Display Adapter Option Disk v2.2 (zipped image)

Installs updated SC.EXE (v2.21 from 1992), DIAGS.COM, XGA/2, SCSI, SCSI w/cache, and some other ADFs, and updated DGS files. This is primarily for models 55/65, 56/57, 70-486, 70/80, 76/77, 90, 95, P70, and P75.

If you have trouble installing XGA-2, IBM SCSI, or other late-era adapters, use the XGAOPT disk to update your refdisk (see below for instructions).

Pre-patched reference disks can be downloaded HERE (search for refdisks marked "XGAOPT").

For any system with refdisks after 92/93, these files are probably redundant.

XGA-2 or IBM SCSI ADF Install Failure

From Jim Shorney (edited):
   You need to boot on the XGA option disk and select the menu item to 'Update Model xx Reference Diskette'.

This selection copies Set Configuration (SC.EXE), associated system and option configuration files to your backup copy of the reference diskette (or the system partition). When prompted for the target drive, enter the diskette drive letter that contains your backup copy of the reference diskette.

The new Set Configuration program and associated files allow users to take advantage of the newest features and functions.

This update requires reference diskette of a certain version version (or greater). Any previous version will not work properly with this update.

From Al Savage:
   The problem was: with only an XGA-2 card installed, the memory would count up, then a "165" error occurred. Running a fresh refdisk v1.12, containing the appropriate two adf files (@8fda.adf & c8fda.adf) and allowing Auto Configuration would produce this error:

An error occurred while reading the option adapter file for the adapter in slot X.

and the "165" error would reoccur after next reboot.

The solution: The v1.12 refdisk contains files whose modification dates are all 1990, and does not accomodate XGA-2.

To use the XGA-2 with an 8580, the v1.12 refdisk *must* be modified using the file XGA2ADP.EXE; almost file dates are 1993.

Running XGA2ADP.exe creates a diskette. You then boot this diskette, it creates a RAMdisk, copies files to the RAMDISK, and a menu batch file is invoked. The menu presents several choices of refdisks to update:

• Model 55/65 Reference Diskette
• Model 56/57 System Partition
• Model 70/80 Reference Diskette
• Model 70-486 Reference Diskette
• Model 9576/77 System Partition
• Model 90 System Partition
• Model 95 System Partition
• Model P70 Reference Diskette
• Model P75 Reference Diskette
• Other PS/2 Reference Diskette
• Other PS/2 System Partition

You choose a model, and are prompted for a drive letter to update. I chose A:, and was prompted to insert the refdisk diskette. The refdisk modification process took about three minutes. Rebooting with the modified refdisk — and an XGA-2 card installed — yielded an Autoconfig with no errors, and the following reboot showed no 165 error.
