Hi All, I recently picked up two HP z420 PCs that have a boot block date from 2011 and are still on BIOS rev 1.02. I've been doing some reading and I need to first update to 1.07, then 1.23 before I can update to the most recent (3.96 I think it is), but I can't for the life of me find a download for the older versions. The official HP links are broken and this is the first place I found with any downloads but it seemed like these may be custom edited BIOS files so I wanted to query SMDFlea and see if they could send me in the right direction. Thanks in advance for any help.

You can step up to version 1.23 first then to the latest.Read the comments by DGroves --> https://h30434.www3.hp.com/t5/Busine...s/td-p/8078192

The link for the 1.23 is ftp.hp.com/pub/softpaq/sp64501-65000/sp64701.exe .You can extract the softpaq using 7-zip or winRAR

I appreciate the response. I already found that post prior to responding to this one and could not get the links to work in Edge or using FileZilla on 2 different windows PCs, one an HP laptop.

Do I need to use the PC I am attempting to update to access them?

Thanks Again!

Hi everyone! I assembled two Z420 machines. One started without any issues, but I ran into problems with the second one. The motherboard (618263-002) started up for the first time with a v1 processor. I updated the BIOS, replaced the CPU with a v2, and it stopped booting. Nothing helped, including returning to the first v1 CPU the fans just throttling and the screen remained black. I tried emergency recovery with a flash drive, but it didn’t work 8 flashes and 8 beeps appeared at startup.

I created a dump, inserted the padding section into the BIOS 3.96 from the website, but that also didn’t help still 8 flashes and 8 beeps.

Thank you for your prompt response! Since all the components were purchased separately I don’t have a sticker with the serial or product number.

But based on the BIOS dump the serial number is 2UA4271JTZ
The product number is most likely LJ449AV
The motherboard part number is 618263-002
