Hi all,
This is my first post here (I am very new to forums!) and I hope someone can help. I am looking for a full dump of the BIOS of a HP Proliant Microserver Gen 8 so that I can get this mini server running again. (BIOS version J06 2019-04-04, chip 25Q064A). I think my board was partially bricked after a failed BIOS update.
I got it second hand in this state and all the normal attempts at bios restoration have not worked. I have even desoldered the chip and tried to load the actual BIOS from HP, but it is missing some parts needed to boot the system.

The Samsung S49CG934SU monitor does not power on - no LED indicator activity and no response to power button. However, when 21V power is connected, it immediately draws 0.8A of current with no display output. The motherboard processor gets warm, and there is continuous reading activity from the W25Q128BV BIOS chip.
Suspected Cause:
I suspect the BIOS may have been corrupted during a power interruption while updating the firmware. The official website provides firmware updates, but they can only be installed via USB flash drive.
Troubleshooting Attempts:

Hi, Thanks for all you do here.
I have attached my 16MB dump.
EDIT2: All hardware working fine, I think I just need to update my linux booatloader and all gucci
EDIT:
I can get into bios now! I reflashed as instructed elsewhere. With a minimal POST (just 1 stick of ram , GPU, CPU, no drives) I have loaded into BIOS. I am about to reinstall my other hardware components now.
The clips are such a pain to use, soldering would be a great skill to have.
Thanks for the advice in other threads!

Hp Probook 450 G7 s# SCD0348W35 had a locked BIOS. Bought BIOS and EC chips off Ebay that were supposed to match this machine - the 450 G7. Flashed in the BIOS on chip i bought using a CH341. BIOS unlocked next boot. Some error to contact HP. Entered BIOS and reset to system defaults and rebooted. Machine worked fine but every cold boot the contact HP message popped and everything else worked as fine. Assumed the error was from EC chip not matching BIOS that i just flashed in. So i flashed in the EC that was supposed to match from the EBay chip i bought and instant brick.

TLDR: I would like to have the clean BIOS dump file for my laptop model.
Issue: First, my speaker wasn't working/showing up, so I downloaded the recommended BIOS update (from Jan 4, 2026) on Lenovo Support for my laptop. This didn't fix the speaker issue after restarting, so then I shut it down and pressed the power button for 60 seconds to perform a reset. I'm guessing I somehow messed up the BIOS because now the laptop won't turn on even after trying the NOVO button on...
