Z420 Bios Upgrade for Windows 10
Question: Can I go directly from "J61 v01.02" to "3.90 Rev.A 8-Aug-16" on my Windows 10 PC? If not, what is the BIOS migration path?
--
I have a Z420 Workstation (Product # b2b96ut#ABA) that is running Windows 10 Pro 64-bit OS. The BIOS is "J61 v01.02; boot block date 12/28/11" which appears to have been the initial release BIOS (based on https://community.spiceworks.com/topic/319873-hp-z420-bios-confussion). See the last post on that thread which was made by HP staff.
The above referenced article says, in part: "We do recommend that customers upgrade to the “latest” BIOS; however, the Z420 BIOS situation is a little complicated. The Z420 (and Z620 and Z820) BIOS went through an unprecedented amount of change between initial release and the introduction of Windows 8. The UEFI ingredients necessary for Windows 8 were simply not available in time for initial release. One unfortunate side effect is that BIOS 1.02, which shipped for the first 2 months of Production, cannot upgrade directly to any 2.XX or 3.XX BIOS. Any system with BIOS 1.02 must first upgrade to a higher-numbered 1.XX BIOS before being upgraded to a 2.XX or 3.XX BIOS. Because of this, we need to keep the latest 1.XX BIOS on the web as a “stepping stone” for customers that need to upgrade from BIOS 1.02. We are not actively updating the 1.XX BIOS stream, but have been updating that BIOS with any critical, security-related bug fixes. It just so happened that 1.21 (with recent critical fixes) was released just after 3.06 (the latest, greatest BIOS). Customers should upgrade to 3.06 as the “latest” BIOS."
HOWEVER, the above article was dated in May 2013 -- which precedes Windows 10.
The Windows 10 download page (http://h20564.www2.hp.com/hpsc/swd/public/readIndex?sp4ts.oid=5225034&swLangOid=8&swEnvOid=4192) lists only "3.90 Rev.A 8-Aug-16" and "3.88 Rev.A 19-Jun-15" BIOS revisions.
