I'm trying to find documentation on getting a Motorola 5100 board to boot
from a
hard drive. What I spefically am wondering is do I need a "boot loader",
or is that
built into the kernel?
I can build a kernel (2.4.11) which works and until now have been using a
ROMFS, built into
zImage.initrd.pplus. I am currently able to netboot or boot from flash.
I am thinking I can rebuild this kernel root=/dev/sda7 and I should be able
to get it
to use the hard drive as /. My question is can I just put that new kernel
on a
bootable partition on the hard drive and get PPCbug to boot from that
partition, or do I need
some form of a bootloader? (yaboot, lilo, other) I do realize I should
be able to
flash this kernel and then have the board boot from flash and use the drive
as /.
Is this the more common approach?
If there is a good write up on this I would be glad to read about it, I
just haven't found it yet.
I do have the PPCbug manuals.
Thanks,

HI,
I can confirm to you that booting from network and using a HD partition as
root filesystem works correctly. I haven't tried yet to boot from HD, but
I've read something interesting about this argument in the ppcbug manual at
the GEVBOOT command and the PBOOT command.
I hope this can help you.
Bye.
