Adaptec AIC 7890 SCSI BIOS v2.01 (1998). The aic7xxx driver reports its
version number as 5.1.10/3.2.4 (Kernel 2.2.3) and 5.1.12/3.2.4 (newest
SuSE). Booting directly from CD works either.  Under DOS 6.22 I can access
CD and CDW without problems, so I think also that there are no termination
problems. My vendor put an active termination at the SCSI connector. Is
this ok? Booting from DOS using loadlin does give the same errors like
before. Here I tried also the "no_reset" option without difference.
