In short the guy removes the 2 BIOS chips, then he re-flashes them using a "universal programmer".
So flash memory, can be written to and read from across all chips? eg, is access the flash on an ATTINY85 similar to how you'd read and write to a BIOS chip? (not a question, me typing to try and understand what's going on here)
Question 1. After the guy desolders the 2 BIO's chips, what's that "hand clamp thingy" which resembles a 12v car battery charger clip .
Question 2. If all you need to do is read in all the bytes from a flash dump, could you not then store it on anything providing there's enough room? - if so is there some kind of standard way of doing it?
EG - could i take an Arduino (use it as an ISP) then read/write contents to/from a BIOS flash, or anything for that matter?
