Can´t find BIOS for Xeon Z4 G4 Workstation, only Core-X Workstation

[Z440Roger]

Does anybody know why HP has removed all BIOS files for Z4 G4 Xeon Workstations? I can only find the BIOS for their Core-X Workstations.

There has always been 2 versions listed under BIOS for this workstation, but now there is only 1 listed. I have seen differences before depending on which Country/Region one choose but now it makes no difference. (One version for Xeon Workstations and one version for Core-X Workstations.)

you will need to contact HP support directly for this issue, as we are users just like you there is not much we can do about this

Just as DGroves often states: 'Google is your friend'.

So I Googled for the string "HP Z4-G4 Xeon Workstation System BIOS" , and looked for any mention of the latest version number 2.74.

Sure enough - I immediately found this link:

g9t6170.houston.hp.com › pub › softpaq

TITLE: HP Z4-G4 Xeon Workstation System BIOS VERSION: 02.74 REV: A PASS: 1. DESCRIPTION: This package contains the System BIOS image and flash utilities for ...

That link leads to HP publication describing the latest BIOS update for Z4-G4 Xeon Workstation:

ftp://g9t6170.houston.hp.com/pub/softpaq/sp121001-121500/sp121440.html

However, the desired BIOS update package sp121440.exe itself is located at the following official HP link, (near the BIOS package sp121442.exe for HP Z4G4 Core-X Workstations):

https://ftp.hp.com/pub/softpaq/sp121001-121500/sp121440.exe

It can easily be downloaded and saved using Windows Explorer rather than use a browser.

So it turns out that HP did prepare a BIOS update version 2.74 for Z4-G4 Xeon Workstation, but HP for some reason did not publish it alongside the rest of tha updates for Z4 G4. DId someone at HP have second thoughts about this specific update?

That´s what i wonder as well, but found it more interesting that HP has removed all versions of the BIOS to the Xeon Workstations, iow all pre 2.74 versions as well. No one has access to them, they have all vanished from the download page.

The issue is that no one can download any version of the BIOS to their Xeon Workstations. The Xeon Workstation BIOS has vanished from the download page while the Core-X Workstation versions are still there. It has been and should be two versions available, one for Xeon Workstations and one for Core-X Workstations. 

To all:

I don´t need to upgrade the BIOS and posted this thread to see if i was alone seeing this. I have noticed during the years that depending on what Country/Region the site defaults to one can get different results. This seems not be the issue this time.

ok, I understand better

at this moment, I can not display the page, in a certain country, as we can often do

OK, the English version of HP publication quoted by Prométhée can be viewed in the following URL:

https://support.hp.com/us-en/document/ish_4168405-4168434-16

It turns out that this matter has a much wider effect than originally thought: all HP Zx G4 workstations are affected, and a few others, too. (Be sure to click on the + sign to view the list of affected products).

Now both versions are available again. It was probably a glitch in the Matrix...
