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.
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
"EXCLUDE = 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
INSTALL program. If the device works in another system, the problem is
likely due to incorrect configuration.
