This is the next board I want to port coreboot to. And the three logs are attached. "Sissy" is what I name the machine the board is in, after SiS. :D
The flash chip i know for sure is SST 39SF020A. It needs a board enable, for which I have figured out 3 of the 5 operations involved, thanks to Luc's slides up at Phoronix.
It used a soldered PLCC32 flash chip. I soldered a socket on myself, and the chip miraclously survived. But I have not been able to get another of the same chip for backup. All my 3 spares are DIP32.
Super I/O is IT8705F, already supported. So it looks like all that's needed is porting SiS630 from coreboot v1. I think I would also be the first to port a single chip chipset to v4.
Thanks to a previous thread on this list, I got the '630 datasheet, but I don't know for sure what is different between it (the 630) and my chip (630ET).
Appreciate all the help I can get for this one.

Sweet! I have a bunch of SIS 630 boards laying around, anything I can do to help just let me know :-)

Must not be exactly the same, any parallell 5V flash will work fine.
SST39SF040 may be easier to find. Am29F040, AMIC A29040, EN29F040A or ST M29F002B would work too. Where are you located?
