The SCSI HOWTO has a few things to say about the Adaptec 2940 family:
[begin quote]
5.6. Adaptec 274x, 284x (Standard) 294x (ALPHA)
A newer version which also supports the Adaptec 294x boards is
available at
ftp://ftp.ims.com/pub/Linux/aic7xxx
Supported Configurations:
274x 284x 294x
EISA Slots : 1-12 N/A N/A
Ports : N/A ALL ALL
IRQs : ALL ALL ALL
DMA Channels : N/A ALL N/A
IO : port mapped, bus master
Autoprobe override :
kernel command line :
aha274x=extended
(to force extended mapping)
Notes:
1. BIOS MUST be enabled
2. The B channel on 2742AT boards is ignored.
3. CONFIG_PCI must be set if you are using a PCI board.
[end quote]
The "ALPHA" bit is indicative. Not guaranteed to work and all that.
Anyway, maybe this'll help somewhat, as a starting point...?
