Currently there is no support for running RedBoot from an IDE
disk. The floppy booting RedBoot simply occupies the first 120-odd
sectors of the disk. Doing this on a hard disk would destroy any
filesystem on it.

For booting from formatted disks we support GRUB, but only to boot
eCos applications, not RedBoot since using a bootloader to load a
bootloader seemed a pointless exercise.

See the following documentation for details:

You could try adapting the floppy bootstrap code for the hard disk you
are using, you will need to adjust the sector and track counts and the
device identifier. You will have to find some BIOS documentation to
tell you what to do.

If the CF implements an IDE interface then you can boot from that in
exactly the same way as from a hard disk.
