scsi not working (internal zip drive 100)

[BigCletus]

Hooked this drive up on a win2kserver/linux maching (dual-boot). After much tweaking with the jumpers on the card, using a aha152x driver under win2k got it working. Under linux is a different story. Added append="aha152x=0x140,9,7,1" in lilo.conf, no luck. Added options aha152x io=0x140 irq=9 in /etc/modules.conf. The when I type modprobe aha152x, i get this output from dmesg | grep scsi:


SCSI subsystem driver Revision: 1.00
aha152x: BIOS test: passed, detected 1 controller(s)
aha152x: resetting bus...
aha152x0: vital data: rev=1, io=0x140 (0x140/0x140), irq=9, scsiid=7, reconnect=enabled, parity=enabled, synchronous=enabled, delay=1000, extended translation=disabled
aha152x0: trying software interrupt, lost.
aha152x0: IRQ 9 possibly wrong. Please verify.


How can the irq of 9 be wrong when that is what the jumper is set for and that is the software irq under win2k? Before with different settings for the card under linux it seemed to actually load once without errors. However, when I try to mount /dev/sda, I get "unknown device"? Any clues? Thanks.

Didn't you already post a question about this in General? None of the suggestions there help at all?

yes. no. I got it to work years ago with an old version of redhat, 5.0 i believe and I dont remember having to use ppa at all. I thought that was just for the parallel port version...mine is scsi

Try cat /proc/interrupts to see if anything else is using irq9.

This may (or not) help. Try disabling PnP OS in the bios.

And also slapNUT's suggestion to see what resources are being used.

cat /proc/ioports

Finally got it working! I had to go into my BIOS and set ISA irq 9 to "reserved". After I did that, I modprobed aha152x and it actually worked. Then, when I went to mount the zip disk, it worked! Amazing. Didnt need to compile a kernel or reinstall or use ppa. Just that module. Thanks for the suggestions on the bios settings. :)

Good job... Glad you got it working.
