Yes I read the BootPrompt-HOWTO, that's where I got the
append = aha1542=0x234 syntax. However, the driver source
code is where to get the module parameters (as per this same
HOWTO). In the aha1542.c file, there is a section that
explains why you cannot pass IRQ or DMA parameters. The
driver was apparently upgraded to issue request_{irq,dma}
calls that query the board for that info. I suspect that
the reason the module can't find the IRQ for the board is
because it can't find the board. This was working fine
before I changed the base_io, and it still works fine under
DOS/WIN. I'm sure I just need to properly inform the driver
module of the new base_io address (0x234).
Does anybody know how I can tell what this value is set to?
I mean I set aha1542=0x234 in lilo, but how can I tell if
its been set in the kernel? Can anybody tell me if I even
set it correctly? It looks good to me, using the aha1542.c
file as a guide, but I'm rather new at this. By the way,
I upgraded to kernel 2.0.12 last night, but no magic.
Thanks in advance

Problems with aha1542.o ...
I posted earlier about this, but I have more info and it seems to be specific to this module and not lilo. I had to change my base_io from 330 to 234 to accomodate my MPU-401 interface on the Audiotrix Pro card. This works fine under DOS/WIN with a /P234 switch at load time for the driver. The analogous entry for the aha1542.o module is a lilo parameter aha1542=0x234. I've added this to the top of my lilo.conf file with 'append = aha1542=0x234' but I still get errors. I tried doing depmod -a (which showed some unresolveable symbols in sound.o :-() and modprobe but no luck. I did an strace -f on it and it seems that its unable to find its irq. I can't find any way to pass a parameter to the module to tell it what irq I'm on (10)! I took the advice from someone on the list and checked out /proc/... but there are no conflicts there (I suspected not). I plan on upgrading to kernel 2.0.12 in the next few days, but this module hasn't changed at all (I think the sound.o will be fixed though!). If this magically fixes anything, I'll let you guys know. In the mean time, anyone got any ideas? The load time error I get is this: Initialization of aha1542 failed scsi_mod: Device or resource busy which is pretty general. I can send the strace file to anyone willing to have a look. Thanks in advance! Richard G.
