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

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