Yes, you have to recompile the kernel. You should compile scsi disk
support, and support for your SCSI controller card. You currently have no
SCSI support.

Well, you can compile the scsi disk and scsi controller options as a
module first, then try this:
# modprobe aha152x aha152x=0x340,12
'0x340' is the portbase, and '12' is the IRQ. I'm pretty sure those are
the default parameters, which should work. You can try and vary those a
bit if they don't work. Check the code for other irq's and port addresses
if you are stuck.
Once you figure out which address/irq it is using, you can add the
following lines to /etc/conf.modules:
alias scsi_hostadapter aha152x
options aha152x aha152x=0x340,12
and subsequent 'modprobe aha152x' will load it properly.
If you choose to compile it in the kernel, instead of as a module, you
will need to make changes to the aha152x.c file to reflect your current
card settings.
To the developers:
I understand this card doesn't have a bios. Therefore it can't be probed
to figure out its addresses/irqs. I do know that it would be possible to
try these combinations when loading, and see which one works. Why aren't
we doing this? Can I add that Win95 successfully finds this card?
