PS/2's with XGA on a daughter card (not on motherboard) have
2 known problems with Fixed Frequency displays like the ImageAccel
Color 21/76, Color 19, and all ImageAccel Grayscale displays.
Following is a description of the fixes we've developed for these
problems. These fixes are available now in LIMITED quantites
for customers who request it. These parts will be included in
ImageAccel controller boxes in October 1993.
The problem descriptions;
-------------------------
Problem #1.
On any IBM PS/2 with an XGA or XGA-2 display adapter daughtercard
(IE: PS/2 Valuepoint Model 77), installing Fixed Frequency displays
is difficult without a separate XGA-compatible display attached for
the system configuration.
NOTE: If you have a multisync ImageAccel display, you can use it
for the XGA compatible display to setup your ImageAccel card, and
then switch the video cable from the XGA card to the ImageAccel
card when the MicroChannel configuration setup is complete.
Problem #2.
Once ImageAccel is configured and installed, and Windows 3.1 is
running, changing to a DOS window or DOS Full-Screen shows
garbage on the screen (this is documented in the ImageAccel
READ.ME file for Release 1.01 and 1.02).
NOTE: This problem does not occur with the OS/2 display driver
for ImageAccel.
The FIXES:
Problem #1 Solution
-------------------
Step 1: Install the ImageAccel Display adapter into the IBM
PS/2 mocrochannel video slot.
NOTE: If you add or remove any other adapter cards to
your system, you have to keep the connector installed on
the XGA card, and boot using the boot disk to re-run the
configuration program again.
Step 2: Put the diskette labeled "IBM PS/2-XGA BOOT DISK for
ImageAccel" into the A: drive. (Contact Cornerstone
Technical Support for information on obtaining this
diskette).
Step 3: Place the Special connecter (we provide) onto the XGA
display adapter port.
Step 4: Boot the PC with the ImageAccel boot disk and special
connector installed. (Note: This is not a DOS format
diskette - its not readable by DOS).
Follow all the prompts for Automatic Configuration.
Remove the ImageAccel Boot diskette and re-boot.
When prompted for the ImageAccel configuration file, put
the Windows 3.1 Display Driver disk 1 into drive A:.
Follow the remaining instructions and the PC will reboot.
DOS should now be running on the ImageAccel display.
Problem #2 Solution
-------------------
NOTE: The file PS_XGA.BAT is located on all Release 1.03
diskettes in uncompressed form. You must manually copy this
file from the Release 1.03 diskettes to your \Windows\System
directory for this fix to work.
Step 1: Install the Windows 3.1 XGA driver.
While in the Windows directory, type SETUP from DOS.
Insert the diskette labelled "IBM PS/2 XGA Device Drivers-
DOS, Windows and AutoCAD Support" (V 2.02). This disk is
supplied with your IBM computer.
NOTE: Cornerstone tested the V2.02 XGA driver for this fix,
but previous versions of the XGA driver should work as well.
Select the Display entry under the System Information
window, and scroll down to the bottom of the list.
Select the entry: "Other (requires disk provided by a
hardware manufacturer)"
When prompted, enter: " A:\WINV31" and press enter.
A list of XGA drivers will appear. Select the one shown
as "IBM XGA v2.02 640 x 480 256 color". (you may use any
VGA driver listed with 256 Colors and 640 x 480 parameters).
NOTE: If you are using an XGA driver other than the V2.02
driver listed, you'll have to edit the batch file and rename
the line in PS_XGA.BAT: XGAVD202.386 to your XGA driver
to reflect the driver version you're using.
Exit to DOS when this step is complete.
Step 2: Install the ImageAccel Display Driver.
You have to rename IASETUP.INF file to OEMSETUP.INF on
distributed ImageAccel Display Driver diskette.
Follow the usual steps in the Manual for installing
ImageAccel. Don't run Windows yet.
Step 3: Copy the file PS_XGA.BAT from disk 1 of the Windows 3.1
display drivers for ImageAccel into the \WINDOWS\SYSTEM
directory.
In the \WINDOWS\SYSTEM directory, run the DOS batch file
called: "PS_XGA.BAT".
Run Windows.
