I have two SCSI controllers. Attached to one is the disk which contains my UltraPenguin distribution. On the second one, I sometimes have disks attached, and sometimes not. If I don't have disks attached, it labels the disks on the first controller as sda and sdb. However, if I *do* have disks on the second controller, then those get labeled sda, sdb, sdc, and the disks on the first controller get labeled sdd and sde. This causes problems because it is setup to mount partitions sdb1, sdb2, sdb3, etc. short of having two versions of /etc/fstab, how could I have the first controller always be recognized first? I believe it would involve adding something to the kernel boot parameters, eg. in silo.conf have a line "append=xxx=yyy", but I'm not exactly sure what to fill in for the xxx and yyy. Something to do with a driver name and base address? Thanks (please ask if you need more details), Charu
