aha1542 scsi does not detect

[Oktokie]

Dear Guru,
Can you show me the light? I need some enlightenment over here.
Okay..I've first compiled scsi low level driver (aha1542.o) and some
part of scsi
operation into modules(scsi hard / scsi tape / scsi cdrom supports) then
I realized
that my scsi card was not even being detected....

I've already tried linux boot prompt parameter passing into kernel.
aha1542=<port address>[<buson>,<busoff>[<dmaspeed>]] but it did not
work.

So, I decided to compile every things into kernel instead of modules...
so I did it. It appears to be detecting my scsi adapter all right but it
screws up after
my card is probed. I am stuck now....somebody enlighten me.

I am not using any internal scsi devices and the card is properly
terminated. I am
using only Iomega extrnal scsi zipdrive to test this new scsi kernel.

Below is the error messages that I get when my kernel detects with newly
build all
necessary scsi options buildin(not as modules)...

Info: baseaddress=ox334, irq=9, dma=6 on aha1542 scsi host adapter.

error messages:
SCSI: ABOARTING COMMAND DUE TO TIMEOUT: PID0, SCSI CHANNEL
ID0, LUN0, TEST UNIT READY 00 00 00 00 00
SCSI HOST 0 ABOART(PID0) TIMED OUT - RESETTING
SCSI BUS IS BEING RESET FOR HOST 0 CHANNEL 0

Hem...somebody help me out. Thanks in advance

I'm not sure if this will help but here are few things to check. Open a
shell and "cd" into /proc. The type:
more interrupts
more ioports
more dma

I have my AHA1542CF set at IO 0x334 IRQ 11 DMA 7 and it works fine. You
might have a conflict with your Video Card as a lot of them are on IRQ 9
and Linux will not share and IRQ like Windoze. WHen I "more
/proc/interrupts" on my machine the video card doesn't list but it works
fine. Here is what my machine looks like in case you want to compare.

As you can see my Sound Card is real close to my SCSI but they don't
conflict.

Hope this helps,
