During BIOS update to version 3203 something went wrong and I was left with an unresponsive system. No post, no boot, no nothing. Red led on the mobo indicated CPU problem, but I was sure it must be the BIOS. Tried everything, pushing the mem OK button, resetting cmos, taking out battery, everything, but nothing worked, the system was dead and stayed dead. So I started searching for the BIOS chip. As it turned out it is a small 8 leg chip next to the light blue Sata port and can simply be lifted out of the board with a small screw driver. As I have a similar system (Gen3) I decided to give " hot swapping" a try. This turned out to be very easy, but, unfortunately, didn't work. Still no go! Then I got me a simple eprom programmer and decided to give it a try to re-program. As the programmer connects to (another) PC using a parallel cable, the process took almost one hour between erasing, programming and verifying, but....success! System is up and running again! For the record, the BIOS chip is a WINBOND W25Q64BVDAIG and goes into the ZIF socket of the programmer without any adapter. chi09es.
