t/ , but the disk drivers I tried to use with centos 4.3 did not work,
saying that the disk did not containt appropriate drivers for the
hardware.

issue?

Yep, I have ran into similar probs with adp94xx drivers from
IBM/Adaptec. Quite a pain in the ass. The drivers endedup working, but
took some trickery. I ended up getting the installer going, then
switching to the second virtual terminal, mounting the .img disk, then
manually insmod'ing the the kernel module. *Then* it actually found the
disks, and the install could continue.


> I really need to install centos as an array... and as hardware RAID
and not software RAID.

Lots of other people have covered the hardware-vs-software/fakeRAID
stuff. Linux software RAID works great. Hotswap works well too if you
are concerned about that.
