Hi Casey,
Thanks for your advice.

Your two drives are running in RAID-0 acting as one 76342 MB volume. It

data and re-configure the array.
Whether you meant that re-partition of hard disks is the only
solution? Thereafter re-configure the RAID to 1.
There is no real advantage to using RAID-0 here, the only thing it gets
you is a couple extra megs for your Redhat-ltsp install. And you don't
have to re-install your windows OSes. If I was you I would remove the
RAID-0 array and setup my drives like this, however it does mean
re-installing windows.:
C FAT16 200MB
D FAT32 22G Win98/Win2000 dual boot machine
E FAT32 remainder For Win98/Win2000 data storage
F Dedicated Linux Drive 40G For installation of RH8.0 and LTSP
Running on RAID-1, will the hard disks view as a big hard drive 80G in
total capacity (40G + 40G) ?
If you wanted data redundancy, you would want to purchase two more
Maxtor 40GB drives. Then you could set up a RAID 0+1 array. What this
essentially does is seem like two are running two large drives mirrored.
Then you have a setup like this:
Pri Master: Pri Slave:
40GB -> (Striped RAID-0) -> 40GB = 76324MB Array A
Sec Master: Sec Slave:
40GB -> (Striped RAID-0) -> 40GB = 76324MB Array B
Are the Pri and Sec Masters as RAID-1 (stripping) and Pri and Sec Slaves as
RAID-0 (mirroring)
Then you setup:
Array A: 76324MB -> (Mirrored RAID-1) -> Array B: 76342MB = 76342MB
Final Array with mirroring
Are Array A as RAID-1 (stripping) and Array B as RAID-0 (mirror)?
You could move to this setup without affecting your current partitioning
scheme,
Sorry, I am not quite clear of this advice. Whether the hard disks are
interchangeable without re-configuration/setup ?
however I bet redhat would still tell you have the same
partition table problem, but you would feel better knowing your data is
mirrored.
Whether you meant I can ignore RedHat's warning at time of installation?
There are some tidbits pertaining to your RAID setup. Additionally here
is a URL with some information about the different RAID levels:

Now for your question about:
"The partition table on /tmp/hda is inconsistent..."
Maybe someone else on the list has more knowledge about this error but I
have gotten this in the past on Redhat installs. I chose to continue
anyway and it worked just fine on some systems. On others the system was
unable to boot to redhat without a boot disk. Be sure that you make a
boot disk in case it dosn't install the boot loader correctly. I say
just give it a shot and see if redhat will boot... if not... then you
will probably have to frag your RAID-0 array and use the 40gb drives
independently.
PS: LTSP is an excellent piece of work, thank you Jim and everyone
else!!!
