22 there is the usual root on raid how toos about. The kernel has to
23 know what the raid set is, I havnt tried this on alpha but seeing you
24 cant read the raidtab in etc its auto detected from the partion and
25 disks. I dont know if the partioning that you need to use in alpha
26 supports it? Maybe you can pass the kernel this info at boot.

32 I have a 433au without a scsi controller so I am sure it can boot off
33 ide. I had problems with 2.4 running IDE disks when I was using a
34 miata specific kernel. Generic worked fine though. Lots of messages
35 about interrupts. I havn't turned my alpha on for a few years so
36 maybe its fixed.
