Actually, to my surprise it worked pretty seamlessly. I simply started 
Win98 with the new partitions in place and copied over and the old sec. 
drive disconnected, and it saw the 2nd FAT32 partition as D: without a 
murmer (simply ignored the existence of the in between Linux 
partitions).  So, not a completely bad OS then :-)

I thought that the raidtab file defined this,

    device      /dev/hda1
    raid-disk   0
    device      /dev/hdc1
    raid-disk   1

Doesn't this mean that raid-disk 0 is the canonical disk?
