Thank you very much mates, sry for my later response, you know, hollydays.

About the subject...then so its posible to write and read all spi chips?

This chip work at 70 Mhz or so, ofcourse arduino work at less frecuency. i think this is a problem to write correctly.

Btw there are few documentation about how to use spi serial with cmos chips or flash eeproms, i mean, i want to read all 4 MB from this chips and check hash sum or md5 sum for integrity..how can i do this? do i need another cristal?

Im totally newbie to electronics but i dont care about it...there are no sucessfull without fail.

Any sugestions? 8-)

Well, these chips are macronix mx25L8005 cmos chips, are from a motherboard. I have the detasheet but after read your responses i will look for a flash seller.

The chips are encapsulated on PDIP format, like a cocroach but with 8 legs and there are 2 sockets on the motherboard for this CMOS flash chips, a foxconn blackops.
 
Thank you very much all.

Come on, no hints?, not possible?.

I need some response about it. I know there are eeprom programmer like Willem but i understand that with arduino we can do more, not only move motors and servos or using processing.

I saw that one guy could reflash the atmel on the arduino itsel, emailed him with no response, so i think is possible to reflash a little pdip flash chip.

I think arduino would be more bigger with the flashing of sat recievers, pics, bios chips, etc for example.

Im totally newbie on chips so i need help to take the right direction about eeproms, roms, chips etc.. Tell me a start point about it.

Is possible to burn a bios on a rom chip using arduino? im looking for info about burn a award bios on a rom chip without a motherboard.
