Correct me if I'm missing something here, but couldn't you also build
AHA1542 support as a module and probe for it at boot time (after the
kernel has already assigned scsi0 and scsi1 to the AIC7XXXs? (This is
what my system does).
| Edit linux/drivers/scsi/hosts.c. Find the lines
|
| #ifdef CONFIG_SCSI_AHA1542
| AHA1542,
| #endif
|
| Move the 1542 call to *after* the lines
|
| #ifdef CONFIG_SCSI_AIC7XXX
| AIC7XXX,
| #endif
|
| Make SUBDIRS=drivers/scsi zImage [or bzImage]. Install new kernel, run
| lilo, reboot. You have just moved the 1542 probe to after the aic7xxx
| probe, aic7xxx cards will be controller 0 and 1, 1542 will be
| controller 2.
|
| Alternatively, add these lines to /etc/lilo.conf
|
| disk=/dev/sdb1
| bios=0x80
|
| Tells lilo to ignore the BIOS and treat partition /dev/sdb1 as the boot
| disk.
|
| Which option you use depends on what effect you want. I use the first
| one because my 1542 external disks are rarely powered on. When they
| are powered on, I don't want my PCI SCSI drive numbers to change.
