Have Hitachi Travelstar IC25N030ATMR04-0 with fried PCB(i think), not recognized by BIOS...
PCB sticker is 08K2771-H69401b-NzG418-C9FL

Replaced PCB with PCB 08K2771-H69401B - M5J422-4001 off donor Travelstar IC25N020ATMR04-0.

BIOS still did not detect drive. Note NVRAM number is same, do I have to swap the chip? Or am I going to have to brute force the NVRAM to find original SA coordinates?

Easier to swap NVRAM, or read and re-write.

Yes, it is easier to replace an NVRAM.

Sometimes NVRAM chip get burned inside, that is when it becomes a pain.
