Well, I've gotten further on this, after reading that IDE Hardware RAID is
just a BIOS hack for crappy software RAID and that the md RAID in the
kernel is much better (http://linux.org.mt/article/ata-raid), I decided to
just use the md raid (md.o and raid<x>.o).  However, I ran into the snag
that raidtools is required to finangle software RAID in Linux.  So, since
the ISO doesn't have it (for only a short time, I hope), I compiled it on
my laptop and copied over the binaries to a floppy and mounted that on my
server and started going away according to this helpful link:
http://help-site.com/LDP/HOWTO/mini/Boot+Root+Raid+LILO-4.html#ss4.2

Now I have a slight problem...as I mentioned earlier, the ISO installer
only looks at /devices/discs/* (and possible /devices/scsi if you have
SCSI, haven't tried that), and not /devices/md* (for software RAID).

I now have my (2) 200Gb drives as RAID+1 on /dev/md0 and my (2) 80Gb
drives as RAID+1 on /dev/md1 (stupid onboard software for RAID would only
allow one RAID Array, since it's the "Lite" version!  "Bleh!", I say!). 
But when I go to "Mount Filesystems" I have a choice of disc[0-3], but I
cannot find where to change this on the ISO.

Is there a way to "skip" this part and mount my filesystems as they should
be?  What are the mount points that the ISO Installer looks for to copy
the image?

I will keep hammering away at this.  :(
