Do you have the ASW-1410 v2.x loaded? This is required for virtual memory programs.

I had this problem too until I started using the aspi4dos.sys driver that came with my 1542B. The problem is related to QEMM putting the 386 into virtual 8086 mode. CPU memory addresses may no longer map directly to the physical addresses that are used by the 1542B. The Adaptec driver handles this correctly. -- Jerry Gardner, NJ6A Altos Computer Systems UUCP: {sun|pyramid|sco|amdahl|uunet}!altos!jerry 2641 Orchard Parkway Internet: jerry@altos.com San Jose, CA 95134 Help stamp out vi in our lifetime.

The Adaptec driver handles this correctly. You can also use the QEMM option "diskbuf". "diskbuf=04" works fine on my computer with Adaptec 1542B.
