ASUS P2B-VM User’s Manual 71
Troubleshooting
System Lockup
• If you are using a memory manager such as QEMM or 386MAX you need to
modify the command line in the CONFIG.SYS file so that the address of the
graphics device video BIOS, C000 - C7FF, is excluded. For example, add “EX-
CLUDE = C000 - C7FF” to the command line.
• Remove all unnecessary boards.
• Disable shadow RAM.
• Ensure that the board is seated correctly and that the device has been installed
using the proper utilities.
• Try the device in a different system and reset to factory defaults using the IN-
STALL program. If the device works in another system, the problem is likely
due to incorrect configuration.
Troubleshooting
Because a typical computer system consists of many different parts, difficulties
may arise from a combination of items, from software or hardware installation, to
monitor compatibility. Listed below are several checks you can make to help deter-
mine what the problem is.
Test Patterns OK; Applications Do Not Sync
The wrong monitor type has been selected. Change the settings in the INSTALL
program.
Windows Driver Not Installing Properly
Windows must be running in 386 Enhanced Mode. Incompatible memory manag-
ers may prevent Windows from starting in enhanced mode. If this occurs, remove
the offending driver or memory manager.
Windows NT 4.0 driver cannot pass “Test VGA.”
Please bypass “Test VGA” then load ATI drivers after completing installation.
AutoCAD Driver Not Installing Properly
If using a 386, ensure that AutoCAD has been configured for the appropriate ADI
driver. The protected mode driver requires extended memory.
