I compiled the new grub and installed it onto my hurd partition with root= (hd0,1) install= /.../stage1 (hd0,1) /.../stage2 0x8000 p this was done from the grub program.
Everything went OK, until I tried to boot grub, at which point it froze. C-A-Del failed to reboot, so I pressed reset. Perhaps coincidentally, my CMOS was wiped. I tried to install grub again, without the 'p' option, but it froze again (my cmos wasn't wiped this time). I have also tried to install onto a floppy but it froze too. I compiled grub on a Redhat Linux 5.1 system. hd0 is 210MB. I use lilo as my master bootloader.
