Is the above link one?
If so, where does it plug into, and how do you read the chip?

to clear bios admin password for some laptops read steps below,
Under Dos/ MAKE A BOOT FLOPPY OR CD, you can use debug command to reset cmos CRC stored at 0x2E-0x2F type:
debug
-o 70 2E
-o 71 0
-q
reboot

dbpk , thanks man on information but it sounds very complicated task to whom never done "mission" like that before. Even though I'm ex technician and definitely not frightened clipping reader wires to EEProm, I'm quite rusted :approve: (maybe I'm lazy too 
) and so I need more information how to perform all procedure (for example at which EEProm pins wires have to connected etc). Can you please give me more details and open my eyes?
Anyways, many thanks dbpk :grinthumb

dbpk, again you tell me the bull****. did you do disassembly of nx8220/nc8230? there's no password in eeprom on this MB. and there's no 24cXX eeprom on this board, only 93c4x eeprom(this information is correct for nx61xx series, nc61xx series, nx82xx,nc8230 etc). dbpk, if you don't know, don't speak.
