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!
