grub stopped working after motherboard swap

[Ken Huisman]

Hi,

I was using grub on my pc to dual boot windows and linux and
I recently swapped out my motherboard and on the new one it
gives me an error.  Here are the details:

Old motherboard was an abit BH6, /dev/hda and /dev/hdb were
windows disks, /dev/hdc linux and /dev/hdd cdrom.

Grub booted linux and windows fine off this configuration

I swapped out my motherboard for an Asus A7V133
and now when I boot up I get the following:

GRUB loading stage 1.5
GRUB loading, please wait...
Error 18


Anybody know what this means?  I thought this error had something
to do with grub not being able to access the disk, but I am not sure.

Other info: If I boot linux off a floppy it works fine, however
windows ME seems to have trouble seeing the secondary IDE
channel (I am almost to the point of taking the whole thing back).


I understand there is some restriction in some cases about booting
off the secondary ide channel (lilo for example wouldnt boot on my old
m/b in this config), but given that this worked with my
old motherboard, I don't understand why it doesn't now.  Is there
something in my bios I have to tweak for grub to boot like this?

any help would be greatly appreciated!  thanks.
