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) (scsi0) >Adaptec aic7895 ultra scsi host adapter: foun on pci 9/0 Wide Channel A, SCSI ID=7 32/255 SCB's BIOS enabled, io port 0x0 IRQ 0 IO memory at 0x0 MMAP Memory at 0x0 couldn't register IRQ 0,Ignoring (scsi0) >Adaptec aic7895 ultra scsi host adapter: foun on pci 9/1 Wide Channel B, SCSI ID=7 32/255 SCB's BIOS enabled, io port 0x0 IRQ 0 IO memory at 0x0 MMAP Memory at 0x0 couldn't register IRQ 0,Ignoring scsi: 0 hosts detected total ... ... ... Partition check hda +++++++++++++ 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 :-) Nikolaj -------------------------------------------------------------- | Ph.D. stud., cand.scient. | | K.
