MBX (MPC860) Question

["KiPyo Ryu" <kpryu@sei.co.kr>]

Hi,

I am useing the MPC860 MBX Board (have only 4MB on-board memory) with
FDD and IBM 4GB HDD (2.5").

I will work 'mbxroot.full.tgz' file at
'ftp://linuxppc.cs.nmt.edu/pub/linuxppc/embedded'.

I plan to boot from NFS after compile at PowerPC 603 machine.

I have some question following:

(1) Can I boot from floppy of the MBX system?
if, yes. what is the method?

(2) I would like to know configuration for network booting, and
after network booting, can I install linux to the HDD of MBX system?
if, yes. what is the method?

(3) Can I use the MBX system for self-hosted development system?

(4) I compiled linux 2.2.6 for MBX system at PowerPC 603, then I tried
to
network booting, but didn't booting. what is the problem.

following is the console display message.
