Tip 7) Troubleshooting System Hangs When Loading CONFIG.SYS
Reboot the system. When the "OS/2" prompt appears in white text at the upper left portion of the
screen, press the Alt and F2 keys simultaneously. Read the driver name on the bottom of the
display as they are loaded. The last driver displayed may be the one causing the system hang.
Try booting from diskette to edit CONFIG.SYS and remark out (using REM) the suspect driver.
Tip 8) OS/2 Warp Server Installation Issues
If you are installing OS/2 Warp Server, you may see one or more of the following messages
while the system is rebooting during installation. If so, follow the instructions below to complete
the installation of OS/2 Warp Server.
Issue 1: The CD-ROM drive is not readable.
Fix: Add the following line to the CONFIG.SYS file on the drive on which OS/2 Warp Server is
being installed:
IFS=x:\CDFS.IFS /Q
where x is the drive where OS/2 is being installed.
Issue 2: The system cannot create the DOS environment because of a faulty video driver.
Fix: Add the following line to the CONFIG.SYS file on the drive where OS/2 Warp Server is
being installed:
DEVICE=x:\OS2\MDOS\VVGA.SYS
where x is the drive where OS/2 is being installed.
Issue 3: A Trap D occurs in device driver SINGLEQ$.
Fix: Reboot the system. When the "OS/2" prompt appears in white text at the upper left portion
of the screen, press the Alt and F1 keys simultaneously. A screen of options appears. Press the
<v> key to reset the video to VGA mode. The system will reboot automatically.
Issue 4: System hangs during loading CONFIG.SYS
Troubleshooting process: Reboot the system. When the "OS/2" prompt appears in white text at
the upper left portion of the screen, press the Alt and F2 keys simultaneously. OS/2 will display
the driver that has been loaded at the bottom of the screen. This will help you identify the last
driver loaded when the system hangs. You can remark the suspect driver to isolate the reason for
the system hang.
