Hmmmmm.
you post this to 5 or 6 linux groups and then report the *win95* 
errors????

first off the card is jumpered to IRQ 9, and you are making windoz think 
its on IRQ 12. if you dont kow how to correct this Im not going to tell 
you.

if you perchance *did* mean to ask for a linux solution, I'll give you 
that. the ADA 1505/1515 are very old ISA cards, and you need to load a 
specific module and pass it exact perameters. there is no auto detect at 
all for this card. I load mine early in my /etc/rc.sysinit file (I run 
RH6.2)
/sbin/modprobe aha152x aha152x=0x340,11,7,1,1

this will load the adaptec driver and tell it to look for the card at I/O 
port 340, IRQ 11, SCSI address of card 7. I cant remember what the other 
two parameters are, but they are necessary. I actually cribbed this info 
originally from the suse info database :)

also, from your post:
> 	BEN, AS1, AS0, I09, DN: for I-O 140-015f IRQ 9
BEN=Boot enable.. enable the SCSI disk boot bios, a disk at ID 0 will 
become /dev/hda (c:) and a disk on ID1 will become /dev/hdb (d:)
AS1, AS0 are *maybe* DMA chanel addresses, having both on might be a bad 
idea (Im guessing here)
IO9 is probably the IRQ address
I-O 140-015f is the memory address.

for more info adaptec still keep thier tech specs online at
