use the tool 'raidhotadd'

wouldn't use that.

i assume you mean rh 5.2 if so, go in and remove all the lines from
/etc/rc.d/rc.sysinit and /etc/rc.d/init.d/halt that talk about raid. just
remove them all. make sure you compile raid modules directly into the
kernel first.

erase everything from /boot on your root disk, and mount your real /boot
there instead. that is the entire point of moving the kernel into /boot,
so it can be a sep. partition. i do this on 6 boxes, works great, no
complaints (other than the silly RH module_info file :)

stupid bios/linux kernel problem. happens all the time with award bios and
drives larger than 8.4 gigs. if you specify on your lilo command line, or
in a lilo append statement:

hda=16383,16,63;hdc=16383,16,63

i use this on two machines with a pair of 8.4 gig disks in each. the three
items are cyl, heads, and sectors. the numbers i give are the 8.4 gig bios
maximum, and is what most drives of this size report. this will get linux
kernel to report disks have same geometry.

enjoy.
