Greetings -
I have just put together a new Pentium PCI system with an Adaptec 2940U.
I had the Adaptec 1542B ISA card left over, so I decided to use it to
run my slow SCSI1 tape drives (an Archive Viper 150 and an Exabyte 8200).
I jumpered the 1542B to Interrupt 14 so as not to conflict with the 2940.
I don't know if this was necessary or not, but I did it anyway... I didn't
change anything else on the 1542B, including the DMA jumpers, which I
think are set to DMA 2 by default. (?)
Anyway, now every time I try to access the tape drives, I get:
aha0: DMA beyond end of ISA: 0x19cc0a0
st1: bad request, must be between 0 and 0
tar: read error on /dev/rst1: Input/Output error
I think perhaps I need to jumper the DMA to a different number, so I'm
going to try that now. But has anyone seen this before in a multi-SCSI
controller system? Any suggestions would be welcome. Thanks!
dmesg output follows...
Regards,
- Mike
