We've moved to GRUB 2 as a development platform. Please can you check if this bug still applies there, and if it does, reopen it?

I have this same problem on a machine with an AwardBIOS (6.00PG).
It seems that ISOLINUX can boot without any problems from my USB-CDROM drive.

After looking at the ISOLINUX sources, it seems it contains some specific workarounds/fixes for certain (award) bios'es that do not correctly provide information on the (CD) boot drive.

Since both projects use the GPL license, it might be possible to port this code from ISOLINUX to GRUB.

Booting a GRUB CD on an internal IDE drive works fine.
(using (cd) as the setup and root device)

When booting from a USB drive, it merrily reports "loading Stage 2" , then dumps me at the "Grub>" prompt.

setup(<tab> gives me;
Possible disks are: hd0 cd

setup (cd)

gives me;
Error 21: selected disk does not exist

Something lies!

Anyone any ideas?
