I'm trying to install Slackware 3.0 onto a 486 DX2-66, 16MB machine and
am having no end of problems. The machine has no IDE hardrives and I'm
trying to use an Adaptec 1540B SCSI adapter to install onto a pair of 1GB
drives using a SCSI CDROM drive in an external box. I'm using the SCSI
boot disk (although I've tried the ASCSI one also). The aha154x is set
at I/O 0x330, IRQ 11, DMA 5 and SCSI address 7. I've tried the
installation process both with and without the BIOS enabled. The failure
occurs when detecting the aha154x and I get the following message
"aha1542_in failure(3); unable to determine Adaptec DMA priority,
The only cards present in the machine are an I/O card (w/ IDE disabled),
a video adapter and the Adaptec 1540B. I've run out of things to try.
I've previously installed Linux onto another system (all IDE drives,
however) without any problems. This one has me stumped as the only thing
I can think of is that the card is disfunctional, however, the card
works fine running DOS/Windows 3.11.
Any suggestions would be greatly appreciated.
