K7T266 Pro2 RU, Raid-0 & Linux

Question

When I try to install either Red Hat 8.0 or Mandrake 9.0 on my K7T266 Pro2 RU, which has 2 x 40GB drives configured as RAID-0 (ie 1 x 80GB), both versions of Linux see the two physical drives and not the one logical stripe array. Why? It almost seems that the Linux drivers for the Promise 20265R are treating the raid channels and normal IDE channels. I want to install Linux onto the RAID-0 stripe!
I have searched for guides/tutorials on installing Linux on RAID, but all the ones I found only talked about RAID-1 (Mirroring).
Windows 2000/XP only sees the one logical drive.
Any help would be appreciated!  
Chris.

The installer is wrecking the /etc/raidtab file when trying to detect existing raid arrays.
Solution: Format a floppy disk with a DOS filesystem (in Linux, you can use the command "mkdosfs /dev/fd0"). Copy
use detect_devices;
package detect_devices;
log::l("PATCHING");
*raidAutoStartRaidtab = sub {
    my (@parts) = @_;
    log::l("patched raidAutoStartRaidtab");
    $::isInstall or return;
    require raid;
    #- faking a raidtab, it seems to be working )
    #- (choosing any inactive md)
    raid::inactivate_all();
    foreach (@parts) {
   my ($nb) = grep { !raid::is_active("md$_") } 0..7;
   output("/tmp/raidtab", "raiddev /dev/md$nb\n  device " . devices::make($_->{device}) . "\n");
   run_program::run('raidstart', '-c', "/tmp/raidtab", devices::make("md$nb"));
    unlink "/tmp/raidtab";
use raid;
package raid;
*prepare_prefixed = sub {
    my ($raids, $prefix) = @_;
    log::l("patched prepare_prefixed");
    $raids or return;
    &write($raids, "/etc/raidtab") if ! -e "/etc/raidtab";
    eval { cp_af("/etc/raidtab", "$prefix/etc/raidtab") };
    foreach (grep { $_ } @$raids) {
   devices::make("$prefix/dev/$_->{device}") foreach @{$_->{disks}};
 to the floppy disk. Remove the floppy and reboot using the Mandrake Linux 9.0 CD1 to do a CD-ROM installation. During boot, press F1 at the splash screen, then place your floppy disk that contains patch.pl in the floppy drive. At the prompt, type "patch", then follow the installation as usual.
Hope that helps
