someone should document how one of the most stable predictive chips on any motherboard become the bane of human existence.
EEPROM
The problem isn't with the firmware once it's there ... it's getting it to the EEPROM that's the problem.
That's not the chip's fault, it's the connection between where the software comes from and the EEPROM itself.
It's not like you can pop it out, slap it in a dedicated chip burner, and pop it back in your PC.
I've dealt with a lot of EEPROM's in my point of sales repair days. Some of those old Panasonic units had sets of 6 and 10, and it was not uncommon for them to go bad. Those little receipts you get inside your McDonald's lunch bag ... all come from a tiny little printer that is run by an EEPROM chip with system specific proprietary firmware in it.
You have to burn them, test them, retest them, make sure you had the right installation software to match the firmware update ... it's a nightmare unless you do it all day long.
So, yeah, the chip itself is quite stable all things considered.
