    _______________________________________________________

Details:

Using 1.97~beta4, with Ubuntu Server 9.10 x64.
I have two drives, configured as a raid 1 with dmraid.

When booting, I get the following:

GRUB Loading.
error: cannot get C/H/S values
grub rescue>

>From there, if i type ls, I get the following:

(md0) (md1) (hd0) (hd0,5) (hd0,1) (hd1) (hd1,5) (hd1,1) (fd0) (fd1)
error: cannot get C/H/S values

There is a 1 second delay between displaying (hd1,1) and displaying (fd0). 
There are no floppy drives installed on my system, and the floppy is disabled
in the BIOS.  Interestingly enough, if I re-enable the floppy in the BIOS, and
attach a physical floppy drive, the server boots fine.

If I install grub with just a single hard drive, it also works fine.  Seems
to only be when dmraid is involved.

Attached is device.map and grub.cfg.
