Here's a Microsoft KB article that might help.

Also, you need a boot.ini that points to the secondary drive. This can be done with a floppy boot disk.

You're most welcome... Another emergency thing you can usually do - swap the primary and secondary drives after a primary failure. You'll probably have to change jumpers (IDE either master/slave or use the other cable if cable select, or SCSI jumpers). right after it crashes, make the secondary drive "look like" the primary drive (as far as the hardware is concerned) and you'll probably be able to boot right away. That gives you some time to get another drive and mirror it back with the primary. The other option I should've mentioned is to do the mirror on the disk controller if it has the capability. Doing it with the controller ("RAID in hardware") is faster and generally more forgiving of crashes than doing it with the OS.

I tried swapping the drive slots with no luck. The system is all raid. I've got 2 drives (boot) that were mirrored, and 6 drives which are raid 5. I really thought all the bases were covered, but....
