AMD740G - Not supported yet?

[GS Hunt]

I noticed that there is still a request for AMD740G chipset info almost
a year later after I first posted some info regarding it. Is it in limbo
now?

Cheers,

I doubt anybody was ever working on this. There is, however, support for
AMD's RS780 chipset which might be fairly similar, so if you have 740
hardware, feel encouraged to let us know how far you get with the RS780
code.

According to my sources, AMD 740G is basically AMD 690G, but you may
have to change one or two PCI IDs. That could result in a working
system. I don't have the hardware, so I'm unable to test.

There is actually a good comparison of features here of 740 vs 690:

Try it out and let us know what problems you find. Full specs are 
available for the chipset.

Alright then. I will give it a try then.

I was looking at the suggested links on coreboot to buy bios chips, and
couldn't decide what chip would work. It takes some socketed spi chip.
On my particualar board it is 1 MB, but and some other 740G boards seem
to have 4 and 8 MB Its an 8 pin  chip. Any suggestions on a suitable
bios chip would be greatly appreciated.

Thanks,

Gary

Flash chip size is measured in bits. Your 1Mbyte chip is 8Mbit.

You could get

Macronix
8Mbit: MX25L8005PC-15G
16Mbit: MX25L1605DPI-12G
32Mbit: MX25L3205DPI-12G

Winbond
8Mbit: W25X80VDAIZ
8Mbit: W25X80AVAIZ
These are actually legacy part numbers, they have new produts but
there are too many PDFs for me to list them all here. Check out
http://www.winbond.com.tw/hq/enu/ProductAndSales/ProductLines/FlashMemory/Se...
for the full list.

bios-repair.co.uk/bios/eeprom.htm sells some of these, not the
32Mbit, but they're a bit expensive. On the other hand they have
stock, don't mind selling single quantity and they ship right away.
