Hello-

I'm using Red Hat 7.2 and GRUB...

I just got my hands on a Promise Ultra 66 IDE controller card.  I have two 
drives in my system and am trying (but having trouble) to move both from the 
onboard IDE to the Promise card.

Currently the /dev/hda1 drive is the boot drive.  I believe once I move it 
to the Promise card it'll become /dev/hde1.

So my question is this: what all changes do I need to make in order to 
switch the drive successfully?  As far as I've been able to figure out I 
need to modify grub and /etc/fstab in order to make this transition?

I've attempted to change grub.conf to be root=/dev/hde1 (this is the 2nd
line in the configuration) and I'm assuming the 1st line is still
"root(hd0,0)" since even though this drive is on a different controller it's 
still the 1st hard drive that grub locates.

Then I changed fstab so that my / and swap point to /hde1 and /hde2
respectivly (used to be /hda1 and /hda2)

I then rebooted- and it stops during the process- doesn't get very far into 
the boot process (sorry, not real familiar with the various stages of the 
boot proc.) It gets to a set of lines where it lists out the hard disk 
hardware- so it looks like the kernel sees it.  But it doesn't make it to 
the point where it mounts the filesystems and runs fsck...

What am I missing?  I didn't try to edit mtab- do I need to fiddle with that 
file too?  Is there something else?

Thanks much for any help!

ps- while fiddling, I've put my main drive back on the motherboard's
controller but kept the second drive on the Promise IDE card- and can
succesfully access the 2nd drive- so I know the issue isn't with some sort 
of low level Promise driver...

some more info:

after all is said and done, this is what will likely be:

/dev/hdd will be the CD-ROM (2nd channel, slave on motherboard- cd's refuse 
to boot when CD-ROM is on Promise card- so must keep it on motherboard's IDE 
controller...)

/dev/hde1 will be /
/dev/hde2 will be swap

/dev/hdh1 will be a miscellaneous drive...  (and I already have this one
succesfully mounted here...)
