installing grub on non-bios visible disks.

[Barry Davis]

I'm using grub-0.90.

I have a flash disk attached via USB which I need to install to - it 
appears as a 128 meg harddrive on /sda in Linux (kernel 2.4.17). The 
Flash disk will later be removed and placed in another box and will 
appear to the system as the primary harddisk. I need to be able to 
install via scripting alone - nothing that must be interactive. This 
will happen very frequently.

The flash disk has its own bootloader which determines which partition 
to boot: 1 or 2.

I need grub to be chainloaded from this first bootloader.

I can't see how to install grub onto the flash disk as the BIOS on the 
machine installing grub does not see the flash disk as a drive.

I was previously using LILO but the size of my initrd is now quite large 
(40MB) and LILO seems to mess up with large initrds, whereas grub from a 
floppy boots it successfully.

Thanks for any advice you can give,
Barry.
