I haven't been the most attentive to BIOS updates for the HP EliteDesk Minis, so I may have missed someone's earlier post.  The HP support site for EliteDesk 800 G4 Mini 35W shows the latest BIOS version as 2.27.  I just performed a BIOS update from within BIOS Setup and my EliteDesk 800 G4 Mini 35W detected and downloaded version 2.29.

 

Just to confirm, I downloaded the HP BIOS update in Windows 11 and started the update from within Windows.  The BIOS updater detected my BIOS version as 2.29, while showing the latest version as 2.27.

Anyone else seeing this?

 

EDIT: I have updated my HP EliteDesk 800 G5 Mini 65W BIOS to 2.21.  My G4 and G5 Mini hacks running BIOS 2.29 and 2.21 respectively are running macOS without issues.  I'll update the BIOS requirements in the first post of this thread.

I have 2 HP G4 800 minis, one 35W running macOS and the other 65W running Linux. Only the Linux 65W had 2.29 available for download and update while the 35W strangely is still on 2.27 on the website. Other than having LAN connected to the computer at boot (that I don't), not sure how to pull in 2.29 for the 35W mini. Any advice or download links?

@ird Maybe HPs support site still needs to catch-up to the latest BIOS update.  In order to update my EliteDesk 800 G4 35W minis to 2.29 (with connected Ethernet), I opened BIOS settings (F10) and updated BIOS.  2.29 was detected as the latest version.

 

EDIT: I don't know how to pull 2.29 without connected Ethernet.

You can download the latest update through HP Support Assistant (on Windows). I have mine updated already, doesn't see/feel anything different.

@CloverLeaf HP's support site for EliteDesk 800 G4 Mini 35W still shows BIOS version 2.27 for me.  If I try to use the "auto-detect drivers" feature on HP's site, it shows no BIOS updates.  I tried clearing browser cache and using different browsers to manually download, but still don't see version 2.29 (latest is still 2.27).  

 

When I performed my manual search, I selected OS as Windows 11.

Selecting Windows 11 or Windows 10 is the same: shows 2.27 as the latest.

I would like to update the BIOS configuration guide (PDF document) attached to Post #1.  My draft is attached and includes the changes below.  If anyone has time to review and suggest changes before I attach the new version to Post #1, I'd appreciate your help.  If the attached document is good, just like this post.  If the attached document needs changes, please propose your changes.  Thank you!

 

The attached guide includes the following changes from the previous version

  • TPM: Hidden -> Hidden or Available
  • VTd: unchecked -> checked

This attached list looks good.

 

Sharing my experience where I have not observed any side effects of the options below (not requesting any changes in your list per se, but just FYI):

 

1) BIOS Sure Start: enabled

2) Intel SGX: SW Control

3) Intel TXT: Enabled

4) HP Sure Recover: enabled

5) SATA 0: unchecked (dGPU version, so don't plan to use external SATA)

6) Unique Sleep State Blink States: enabled

:hysterical: Well, the HP support site has skipped BIOS 2.29 and is now providing 2.30.

EDIT: At the time of this post, the support site does not include BIOS version 2.29 in the BIOS revision history.  This is not the first time that HP's BIOS version releases are confusing.

 

HP has synchronized the BIOS versions of the EliteDesk 800 G4 and G5 Minis.  A new BIOS is also available for the G5 Mini and is also numbered 2.30.

 

EDIT2: Note that, at the time of this post, the BIOS version available via BIOS setup (F10) is still 2.29, while 2.30 is available for download from the HP support site.

I'm curious if this is just a version number change or a much bigger merge for G4 and G5. Two questions that I'm curious about:

 

1) Per your previous assessment G4 could not support any "true" 9th gen CPUs. Does that change now?

 

2) Per your previous assessment, G4 did not impose any PL1/2/3 CPU power limits and allowed good performance scaling of 65W CPUs in 35W Elitedesk SKUs but the G5 put a limit. Does that change now?

@ird Great questions.  The way that someone could perform a quick-and-dirty test without much effort would be to 1) install an i7 or i9 9th gen CPU in the G4 Mini motherboard  2) Run GeekBench CPU test to see if the results change.  My guess is that the BIOS packages for G4 and G5 Minis are still different except for the version number, so the answers to your questions should still be No and No.  Looking forward to test results :)

I'll have to wait for someone to test as well as I don't have any of those CPUs at hand unfortunately.

 

Edit: I'm also struggling to upgrade BIOS without windows. The USB way of putting the .bin files in EFI/HP/BIOS/new somehow doesn't seem to work. Out of ideas here...

@ird I'm not familiar with the "EFI/HP/BIOS/new" method.  See this to see if it helps.

Thank you! Looks like I need a Windows installation no matter what for BIOS installation. I'll give it a try.

@ird After I upgraded BIOS to 2.30 on my EliteDesk G4 Mini 35W, I ran GeekBench 6 CPU benchmark.  My results here.

I have uploaded the latest BIOS configuration document as an attachment to Post #1.  This latest version enables VTd and includes ird's comments here.
