[ale] Large IDE hard drives

[Brian J. Dowd]

I tried installing a master and slave (IBM 45 Gig drives)
on a Red Hat 7.0 system with an Award 4.51PG BIOS.
IBM describes how both drives need to be jumpered so that
they will each address no more than 32 Gigs with this BIOS.
This jumpering scheme did not
work at all if *both* drives were connected either with
the same cable or different ones. I removed the slave 45Gig
and replaced it with a 10Gig. The master 45Gig was *not*
jumpered to reduce the disk space to 32Gigs. They are now
hda (45Gigs) and hdd(10Gigs) and format perfectly.
Fsck has no problems with either drive. IBM does have a fix
available on their web site for this BIOS deficiency but I'm
tired of messing with hardware!
