/etc/grub.conf again
 

Here's my /etc/grub.conf file:

When I power up hdb is loaded.

# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You have a /boot partition. This means that
# all kernel and initrd paths are relative to /boot/, eg.

# initrd /initrd-version.img
#boot=/dev/hda
default=0
timeout=10
splashimage=(hd0,0)/grub/splash.xpm.gz
title Red Hat Linux (2.4.18-14)
root (hd0,0)
kernel /vmlinuz-2.4.18-14 ro root=LABEL=/ hdc=ide-scsi hdd=ide-scsi
initrd /initrd-2.4.18-14.img

There is no mention of hdb and my bios is set to fdo, cdrom, hdo

I'm a little disapointed because I thought I had this grub thing figured out.

i might be misinterpreting something, but what is your actual problem ?

When I power up the OS on drive hdb is the one that is loaded. Why is it not drive the OS on hda?

this is not what your config is saying, please provide more detail on what you did to install it.. is it possibly not just a bios setting?
