I tried that on an a1101 machine we have, and now it won't boot anything
- not even kernels which used to work :S

The sources for PMON on the rs780e machines is here (and they work since
I eventually managed to build + run them):
http://www.loongnix.com:8000/dev/gitweb/pmon-loongson3

The source for the ext2 symlink support I did is here:
https://github.com/jcowgill/pmon-loongson/tree/ext2-symlinks

I have no idea if they will work on the a1101 machine - I couldn't find
a PMON version 4.0.1 in the repo anywhere.

Generally I setup a TFTP server on the local network somewhere and from
either the serial console or on a USB keyboard:

[press c to get to the PMON> prompt]
devls
[find name of network adapter]
ifaddr <adapter> <my ip address>
[subnet mask is assumed to be 255.255.255.0]
load -r -f 0xbfc00000 tftp://<tftp server ip>/<filename>
reboot
