I wrote this because in the command list documentation (http://grub.enbug.org/CommandList), there is reference to a "loopback" command as a replacement for grub legacy 'device' command, and I can't see what use that would have in a real grub boot enviroment. But as I'm not really sure about this, I'll just delete this section. > insmod /boot/grub/normal.mod normal <-- only one of 2 arguments and it > won't set prefix resulting in further problems.

Grub-emu doesn't work for me, and I eventually got tired of rebooting my (only) PC to test things. Should have tried harder though :-(. Thanks for your comments. Thanks also to Seth...
