MVME5100 booting from SCSI disk

From: <hidden>
Date: 2002-02-13 16:30:32

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.
