Dear everybody,
Sorry to interrupt if this is a faq, but I am completely new to this list.
A pointer to the answer might do.
I have a PII333 dual on a intel dx440lx motherboard. I have redhat 4.2
installed on ide-disks. So that part is OK.
I have (for the test case only) atached a single scsi toshiba cd-rom xm
6201b on channel a, which is terminated by jumper setting. It is reported
to have id 1. The cabling looks like
daughter card --------- motherboard ----------- cd-rom
I have enabled termination of the motherboard part.
the scsi bios is reportedly:
adaptec aic7895 scsi bios 1.32S2 - idk4
I have tried both with and without the patch found on
ftp.dialnet.net/pub/linux/aic7xxx
aic7xxx-5.0.19-2.0.34.patch
I try to compile the 2.0.34-kernel with support for the aic7895, but when
I boot it I get the somewhat cryptic messages:
++++++++++
aic7xxx: warning detected autotermination of controller
adaptec aic7895 ultra scsi host adapter at pci 9/1
please verify that driver detected settings are correct
if not please properly set device termination in the adaptec scsi
bios by hitting ctrl+a when prompted during boot.
Cables present (Int-50 YES, INT-68 YES, Ext 68 YES)
Illegal cable configuration !! Only two connectors on the
controller may be in use at a time!
Termination (Low OFF, high OFF)

Then it were hanging.
Clearly I want it to use IRQ 11 and memory F400h and F800h, not the ones
reported. How do I do that?
The cabling report bothers me, since there is only a cable on Channel A.
Channel B (which have two outlets, 16 and 8 bit) have nothing attached.
When the driver is includes in the kernel I cannot see the whole message
because it locks.
When I compile it as a module and issue (only with patch):
insmod aic7xxx aic7xxx='verbose'
I get the message:
Unknown interrupt
(scsi0) Couldn't register IRQ 0, ignoring
(scsi0) Couldn't register IRQ 0, ignoring
scsi: 0 hosts
Initialisation of aic7xxx failed
Unknown interrupt.
Then the system is _dead_
Happy computing :-)
