Me thinks this is not impossible, just hard :-) You'll have to lose the embedded bios
and write your own startup (I posted code to do this a while ago). My thinking is this
- after the final bootstrap (the one that moves Linux up beyond the 1MB mark) I
believe the lower 1MB is completely unused (can anyone confirm this?). Thus if you map
your 2MB's of RAM (either reprogram the chipset/processor or physically remap you
memory) onto the 1MB-3MB range and use your own bootloader to decompress the
compressed kernel directly -> 0x10000.
The final analysis will most certainly show that to get ftp, telnet and finger
running it would be much easier to brew your own system. Check out Flux Research
Group's OSKit or go with eCos, RoadRunner or whatever.

No problem. All you need is a RAM disk of 'decent' size, mounted as root. Oh, wait.
2MB you say. Nah, go with OSKit.
