 Bigger Bigger  Smaller Smaller  Reset Reset

I need help trying to re-flash a bios chip, I looked it up on the internet and I've only found completed projects being showed, not any instructions. Can you please tell me which Arduino ports I connect this chip to: [link]http://pdf1.alldatasheet.com/datasheet-pdf/view/47677/WINBOND/W55F10.html[/link]

Also how do I program the chip with the Asus bios?

From this datasheet for the part:

http://pdf1.alldatasheet.com/datasheet-pdf/view/47677/WINBOND/W55F10.html

I'd have to say, I don't know!

I would guess you could connect it to any 6 pins you wanted and then bit-bang out the transfers, possibly 32 bits at a time, with the up to 128K of data ( 1 Mbit for the W55F10) coming in from a PC.
The different Modes are not explained at all. Perhaps more data is available on the datasheets for these other parts:
"The W55FXX is a serial input/output flash EEPROM series that is typically used as the memory cell
of a W51300 (voice recorder controller) or the ROM code emulator for the PowerSpeechTM series."

Try searching the Playground for a Library for this part, maybe you'll get lucky.  If not, you need to do some more research more first.

I can't really find any information on this, I've tried to research it but I'm confused.
