If you flash the sunday with a 512 Bios, say maybe the new X2 bios, and that bios is bad, goes corrupt or whatever, how would you recover?
I was thinking that doing something like booting the stock MS bios and then using a exploit to run say the default303.xbe would work. In order to do that you would have to know how to boot to the stock MS bios and then enable the chip so you can flash the sunday chip with a new bios. Would this work? If so how do you enable the chip after booting with it disabled?
Until someone comes up with a recovery procedure I will stick with a 256K bios so the other 256K is always there as a backup.

Basicly for the price of a postage stamp you can pull the flash out of it's socket and send it in for a fresh flash. It flashes 512k on the Linux kernel only so it's reliable, there's can always that power outtage etc in the middle of flashing though.

The easist way is to unplug the flashrom and send it in for a quick re-flash for the price of a postage stamp. PM me if you need any assistance.

Here at the shop I would have the oppurtunity to just put that chip into a box it is flashed for and booting and reflashing from there for the target machine or doing the flashrom in a programmer.

If you have a mate with the version you're flashed for you are home free if the headers line up. I doubt the flash ever goes corrupt, maybe just the wrong bios for the target machine is possible.
