A. Troubleshooting
Adapter not detected
This message should only occur when a mach64 ASIC is not detected. If this mes-
sage occurs and a mach64 board is present, it may indicate an I/O conflict, conflicts
between the Extended Memory Manager (EMM) and the video ROM. Try remov-
ing all other boards from the system and booting from a plain DOS disk. Try exclud-
ing the video BIOS address (C0000-C7FFF) from the memory manager. Refer to
the documentation furnished with the memory manager software for information.

come up, or it displays garbage.)
