LinuxBIOS has quite some success with CS5530 based systems. Please have
a look at their mailing list archive at
http://www.linuxbios.org/pipermail/linuxbios/

Once you have LinuxBIOS working, you can also try to add OpenBIOS on top
of it. We can assist you, if you want to try.

Note: it's quite some work to get video output working on the cs553x
since it uses hardware virtualization (vma) for that..  It's doable
though..

I've added a new task to the openbios issue tracking system regarding
this thing:
https://www.openbios.org/roundup/openbios/task12

First you should get a test machine so you can flash LinuxBIOS+OpenBIOS
and experiment with it.. 

Copying away memory is pretty close to the reset vector I guess. IIRC
LinuxBIOS unconditionally initializes the ram controller after a reset,
because it is so fast anyways..

Maybe it shouldn't?

And reinitializing the whole system makes for a very reliable reboot.

An interesting question is how much of this overlaps with kexec-on-panic.
It could be that all we need to do is get the routing right nmi/panic button
to the kernel's kexec-on-panic handler.

Well, In www.linuxbios.org motherboard of thin client do not appear. :)

Motherboard is Pinon Corporation pnc-xm geode GX1, 300MHZ
System boots from 1GB compact flash card in slot1. It's no posible
extract the bios for flash it. No hard drives, no floppy, no cd

Any previous experience in this chipset, and bios (General Software
bios) ?

Only one opportunity if system crash:
eclient >> trash

Any tool to extract actual bios, simulate or something like this?
test to probe compatibility ?

Actually runs win98 and can boot linux.
