Allows one to avoid the flashing stage and might be easier for the more hardware inclined.īefore doing any of these, read up on how flashing BIOS chips works in general. Desolder the BIOS SPI flash and solder in a new one from ebay.You will need to supply 3.3v to the flash chip, from what I’m reading the RPi3 and other devices can’t keep up with the passive drain of the powered off motherboard and so external 3.3v power might be needed.Ģb) Desolder the BIOS SPI flash and then clip onto it - easier to get a good clip and avoids the 3.3v drain of the motherboard
Similar to what people do to flash libreboot onto laptops like Thinkpad T60 / X60. Use flashrom to flash the 2013 boot block after updating the normal way to a suitable E5 v2-supporting BIOS version.
Use a SOIC16 clip and a programmer like CH341a, BusPirate, or a Raspberry Pi. You get one shot to do this right, as a failed flash will probably result in a soft-bricked motherboard! You would then need to do 2) or 3) to recover.

A couple of people there successfully flashed their BIOSes.ĭisable the 0xFF0000 to 0xFFFFFF boot block write protection using the jumper on the motherboard and flash in Linux or Windows using a tool like flashrom or FPT. I can’t link it, but look up “HP z820-e5-2600-v2-ivy-bridge-upgrade” and read through it, especially pages 5 to 10. Same goes for the Z620’s second CPU riser. HP haven’t absolutely confirmed this but I couldn’t find any actual differences between the boards discussed, only how exactly similar they are. The only difference between Zx20 version 1 (sandy bridge Xeons only) and Zx20 version 2 (sandy or ivy bridge Xeons) seems to be the boot block version: 2011 or 2013. For HP Z420, Z620, and Z820, it’s entirely possible, people have done it. I’ve been looking at this a lot recently.
