Do you really have any idea about USB controller ?? USB controller does not require IP address space, it uses MMIO address space which is called non-prefetchable memory in PCI spec. The controller does not need any special init stuff. I don't think USB is supported by 2.2.x kernel neither. Why do you insist using 2.2.x kernel ?

I don't want to use 2.2.x kernel,but for some reasons, I must use the version.
I don't know about USB controller indeed. But why do I see "I/O" addresses in standard bios environment on other boxes(not sis630e chipset),instead of non-prefetchable memory?
In addition,there are patches supporting USB in 2.2.x kernel.I have successfully tried it on standard bios environment with 2.2.x kernel.
Thanks, riskin

Either the BIOS or the HW is buggy.
Hello ollie!
As far as I understand, it's you, Ollie, who wrote that flash_rom program? My SiS630e board (pcchips m787cl+) has an EON EN29F002NT flash part on it and I also have a spare old 1Mbit SST29EE010 part. I saw the program supports SST29EE020... I thought (just an assumption) that SST29EE010 may be similar to SST29EE020 in all but the size, so I patched your program a little (added a record to the flashchips array and also added some #define's to flash.h) so it agreed to flash my spare chip. Unfortunately it didn't work. The flash_rom pretends to work, but quits after "Verifying 0x00000001". The board doesn't boot and when I place the EON part back in place, the board's CMOS turns out to be ruined.
Can you imlement a correct support for SST29EE010 please? It has a sufficient size to put a linuxbios in there, so I'd like to use that part if possible. I hope it is electrically compatible with the SST29EE020 and EON EN29F002NT?
I tried to find any of the parts you supports in local stores, but didn't find anything from that list that would suit my motherboard (I need a DIP32 chip). :(
With best regards, Alexander mailto:spirit@reactor.ru

I doubt it will work. Every EEPROM parts have slightly different command set/cycle for programming. You can not just change the ID and expect it to work.

I am sorry that I can't do it for the moment. Programming EEPROM needs a little bit of trial and error. You can try download the datasheet from SST and modify the 29EE020 code.
