It's rather card-specific, but here goes:
a) On a DAC960PRL, use the "daccf" utility, not "ezsetup" which is what the Mylex web page recommends (THIS ONE IS THE REASON FOR THE FAILURE IN THE FIRST PLACE.)
b) After "ezsetup" screws over your configuration, you *may* be able to recover it by running "daccf -o" and restoring the configuration EXACTLY AS IT WAS ORIGINALLY SET UP. DO NOT START A REBUILD OF THE ARRAY.
c) After (b), DO NOT WRITE TO THE ARRAY. (Boot from a floppy or SuperRescue CD, then try to access the drives readonly.) Apparenly the firmware won't actually write to the disks and start any kind of reconstruction (which would be fatal to your data if you got step (b) wrong) until any write operations happen to the disk set.
