An in-depth guide on how to upgrade the boot block of HP Z420, Z620, Z820 workstations to accept Ivy Bridge (v2) Xeon E5s. Featuring undocumented motherboard headers, flashing BIOS chips, hex editing, and obscure Intel tools!

Follow up to Need help modding bios .bin file. Never done this before

For the daring there is a one-shot software method where you reprogram the boot block of your running workstation, for the cautious or daring who made a mistake there is an almost foolproof hardware method.

Why? Dirt cheap 8 or 12 core workstations with 128GB+RAM and 10+ SATA ports!


omg I love you. This is beautiful

glad you like it :slight_smile:

Do you still have plans to upgrade your Z420?

Is this to skip a gen in the 1155 sockets?

I don’t keep track of names, I know part numbers.

This is to allow HP’s C602 chipset Socket 2011 workstations that shipped with Sandy Bridge CPUs and firmware to use Ivy Bridge CPUs. Is that you mean by skipping a gen?

100%, but school has been kicking my ass, even over the break (got homework over the “break”…) so I haven’t worked on my home server yet. It’s been powered off for months :frowning:

ouch - that’s a lot of work. Feel free to reply and tag me when you eventually get enough time.
