Summary:
LAN Manager 2.00 (any release) local security cannot be installed
correctly on a PS/2 machine running OS/2 1.30 with IBM's XGA video
display drivers (Model 90, Model 95).
The machine will GP-fault attempting to boot, and it will be necessary
to reformat the drive, reinstall OS/2, and make the changes detailed
below to the CONFIG.SYS file BEFORE attempting to install LAN Manager
and activating local security. This behavior is due to a flaw in IBM's
OS/2 1.30 XGA driver, and it is necessary to replace this driver with
the standard VGA driver before installing local security.
More Information:
Because the fault is in the display driver, the user will not even get
an error message on the screen. At most, the first three letters of
the message will appear in the upper-left corner of the screen
TRA
and the remainder of the screen will be blank:
To correct the problem, perform the following steps:
1. Reinstall OS/2, reformatting the boot partition during install.
2. Change the DISPLAY DLL back to standard VGA:
- Copy IBMVGA.DL@ from disk #5 into C:\OS2\DLL.
- From the \DLL directory, type "unpack ibmvga.dl@".
- Reboot the machine from the OS/2 installation disk so that you
can access the active system .DLLs.
- Copy DISPLAY.DLL to DISPLAY.OLD.
- Copy IBMVGA.DLL to DISPLAY.DLL.
3. Edit the CONFIG.SYS file as follows:
a. REMark out these lines:
REM SET VIDEO_DEVICES=VIO_IBMXWY
REM SET VIO_IBMXWY=DEVICE(BVHVGA, BVHXGA)
REM DEVICE=C:\OS2\XGARING0.SYS
b. Add the following lines to replace them:
DEVINFO=SCR, VGA, C:\OS2\VIOTBL.DCP
SET VIDEO_DEVICES=VIO_IBMVGA
SET VIO_IBMVGA=DEVICE(BVHVGA)
c. Save the file.
4. Reboot the machine.
You can now install LAN Manager with local security. The display
quality will be standard VGA.
