3 experiments I've performed to get a system (doing something -
'working' would be an exageration):
[I had a lot of problems before I enabled Math Emulation in General Setup
(CONFIG_NWFPE=y) so this may be essential.]
1. --------
A collegue pointed me to the Brutus distribution
(Get the Brutus distribution from
http://www.research.digital.com/wrl/itsy/linux/linux-brutus.html)
In here you'll find a root disk image that almost works; until
I enabled MATH emulation in my kernel to fix what I thought
was FP bug in some programs - with Math enabled everything
stopped working.
2. ----------
I've managed to boot root-rpc-1999.01.21 with supplemental-1999.01.21
over NFS with a 2.2.1-rmk4 kernel on an EBSA board (with 21285 console
and a dec tulip card). Here's what I did:
unpack root-rpc using loopfs and copy it (use tar) to /tftpboot/<TARGET_IP>
next create /tftpboot/<TARGET_IP>/tmp/instimage/
and unpack supplemental into it. Then in /tftpboot/<TARGET_IP>/dev
(BTW, I export /tftpboot/<TARGET_IP> with link_relative)
mknod syscons c 5 1
ln -s syscons console
cd /tftpboot/<TARGET_IP>/bin
mv sh sh-
ln -s ../usr/bin/sh .
This should allow you to boot. I have not managed to make this run
RedHat install successfully (/bin/init) [I will post a follow up about
this..]
3. ---------- <The Big One>
(suggested to me by Dave Baukus)
Get the following from rawhide.redhat.com/armv4l/RedHat/RPMS/ (or a mirror)
(note I pulled a lot of this crap because I want to fix login)

libpng-1.0.1-6.armv4l.rpm
rpm -i --nodeps --root /tftpboot/<TARGET_IP> *.rpm
This will fail to run /sbin/ldconfig - I fix this with the following:
cp /sbin/ldconfig /tftpboot/<TARGET_IP>
chroot /tftpboot/<TARGET_IP> /ldconfig
rm /tftpboot/<TARGET_IP>/ldconfig
Note that I am running the ***x86*** ldconfig here!
create the syscons/console (see #2) and then boot the kernel
with -b (this is essential as mingetty/login is broken) This
should boot single user.
