I had a closer look at this i815 platform
it contains :
FW82815 FW82801BA SST49LF004A, which seems to be 512KiB flash
Unfortunatelly, it seems that the above flash is soldered to the MBO :-(
Does it mean there's no way I can use the system for L/B or is there some inexpensive way to correct this deficiency?
Not sure if that's a good price, but you can get complete 1 GHZ i815 systems (ie ready for use desktop) here for about $65.
Just a quick thought regarding this, does anyone know if it would be possible to (easily) build a bios-savior-like device for such a case as this? I'm thinking something like this: connect two plcc sockets together, back to back, sodiering together all the connectors except chip enable and/or power. then, de-sodier those connectors from the existing chip. run wires to the motherboard on those lines, and also to a switch, and then also to the pair of plcc sockets. Then, fit a new "savior" chip into one of the sockets, and put the other one on top of the existing chip. Anyone think this would work? would sure save a heck of a lot of hassle. I haven't looked to see how the actual ioss bios savior does this yet, but I imagine it's something similar.

Sure, it will work just fine. I would suggest wiring between the two PLCC sockets however, since they're keyed and don't handle mirroring without help.
Or - make a board for two SMT PLCC sockets.
then, de-sodier those connectors from the existing chip. run wires to the motherboard on those lines, and also to a switch, and then also to the pair of plcc sockets.
I would probably let the switch control one of two AND gates per switched signal, the other input being the signal from mobo and output going to one socket each.

Any chances to make it similar for SPI chips?

Sure, just a few more signals that have to be switched.
