installing grub into a file

[Padraig]

Hi,

I would like to install grub into a file rather than a disk.
I've already created 2 partitions in the file and ext2
filesystems, and the appropriate grub files are in the /boot/grub dir
of the first partition.

I want to install stage 1 to the mbr and 1.5(ext2) to the
boot sector (I think).

So question is can I get the grub shell to do it
(it was giving an error that it couldn't probe the device),
or should I just dd the appropriate grub bits to the file?

btw I was able to get lilo installed by doing some fancy
losetup stuff, but grub should be much easier I think
since it doesn't need to write block locations.

Any ideas appreciated.

thanks,
Pádraig.
