It's my first posting here <nervous
... just kidding>.So, I have a Soyo SY-6BA+ IV motherboard with a Macronix MX29F002NTPC-120 bios chip. As it is written on winsbios.com this chip seems not to be of best qualitiy (to say it politely). To make it short: flashing failed and also re-programming it with a flasher failed with writing errors at random addresses.
I have a defective motherboard with a Winbond W29C020-90 bios chip. Can I use this chip in the Soyo board? I downloaded the specs but I'm still not sure, the pinout is the same but e.g. the where the MX29Fxxx has a reset pin, this pin is just not connected by the W29Cxxx.
Also, I don't know the difference between a 29Fxxx and 29Cxxx chip. Can someone exlpain it to me? I already have asked Arthur from flashbios.org but was suprised by his answer:
> The 29Fxxx are flashable more then once.
> The 29Cxxx are one-time programmable only.
He told me that I can use the Winbond chip for the above board, I just wanted to be sure and get a second expert opinion.
Almost forgot: Both chips have the same 32-pin DIL layout, that would fit
