Hi everyone,

I'm currently working on an HP Z4 G4 Workstation and I’m in need of the 16MB BIOS file for this system. The motherboard is labeled:

👉 AS# L09990-001

Unfortunately, the system isn’t booting properly, and I suspect a corrupt BIOS. I’m planning to flash it manually using a CH341A programmer, so I’m specifically looking for the full 16MB SPI dump for the chip MX25L12873F.

If anyone has a working Z4 G4 and could share a dump (or knows where to find an official or clean version), I’d be super grateful!

Thanks in advance...
