I think the weird grub behavior I've encountered really is related to BIOS limitations. Following the instructions in the grub manual, I built a boot diskette and booted from it, getting a grub prompt. I then issued the following commands, with these responses:
root (hd0,7) Error 18: Selected cylinder exceeds maximum supported by BIOS
- From seagate site: | Some systems BIOS have capacity limitations.

My bios has one of those limitations, I think the 137.4GB one. The grub from 9.3 couldn't boot it, but the one in 10.1 has no problems. Of course, the /boot partition has to be located under the limit, the rest can be anywhere. - -- Cheers, Carlos E.
