Help! How to install linux on MBX860 IDE hard disk?

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

Hello all,

I have a MBX860 with 32MB RAM, a 4GB IDE hard disk and a floppy.
I would like to install linux on a MBX860 hard disk.
I have some question to install linux on a MBX860 IDE hard disk.

I downloaded the following files from
ftp://linuxppc.cs.nmt.edu/pub/linuxppc/embedded/
mbxnotes, embedded_notes, mbxroot.full.tgz, zImage.mbx-2.2.0-pre6,
embedded-2.2p7.tar.gz


1) I have untarred 'mbxroot.full.tgz' in the /sys directory.
2) I have made arch/ppc/defconfig file by using configuration of the
mbxnotes.
   I don't know how to make it exactly.
3) I have compiled on a PowerPC Linux.

4) My server(PowerPC Host) configuration for booting is as follows:
    -> /etc/inetd.conf
===========================================================================

    tftp   dgram udp wait root /usr/sbin/tcpd    in.tftpd /sys/mbxroot
    bootps dgram udp wait root /usr/sbin/tcpd    bootpd
===========================================================================

    -> /etc/exports ==> I don't know how to make it exactly.
===========================================================================

    /sys/mbxroot
===========================================================================

    -> /etc/services
===========================================================================

    bootps    67/udp            # bootp server
    bootpc    68/udp            # bootp client
    tftp      69/udp            # tftp client
===========================================================================

    -> /etc/bootptab ==> I don't know how to make it exactly.

4) I have booted with the created zImage via nfs.
    Dump message is as follows :
    Please let me know what's wrong in this procedure.

===========================================================================

How come the above dump message of 'Unable to open /dev/hda' happen?

Can anybody see what I'm doing wrong, or at least give me a few hints
where to look?

Thank you for your help.
