#1 | Getting rid of boot messages which stop boot unless pressing F1, on HP Prodesk 400 G1 MT datum

Fri Dec 25, 2020 2:14 am

Got the motherboard from a Prodesk 400 G1 MT to play around with. Unfortunately, it seems to have a few error messages on startup:
https://ibb.co/9WYtgVS
Front audio and Front USB 1 are actually connected, but still show this message. They work in Windows with no problems.
Can these 4 messages be removed so that the board boots normally without showing this message and needing to press F1 all the time? There are no BIOS settings to control this from what I see.
Here is the link to the latest BIOS (which I am running): https://ftp.hp.com/pub/softpaq/sp96001-96500/sp96015.exe

Thank you in advance to anyone that can help.

brian105 - Do you see a 2 or 3 pin jumper anywhere on the board labelled FD, FDO, Service, ME, Management etc?
Please do below, and along with that, also show me image of this >> FPTw.exe -i
If you do have a jumper like I mentioned, put a jumper on there or move it away from default to enable, then boot to windows 3 times before doing all this (to ensure activation)

If you have already modified the BIOS in ANY way, you will need to re-flash it back to factory defaults using factory method (NOT FPT)!!!
Additionally, please remove all BIOS passwords, disable secure boot, and disable TPM or Encryption if you have enabled. Do this before moving on to below

If you do not have Intel ME drivers installed, install them now from your system driver download page, then start over here after reboot.
Check your BIOS' main page and see if ME FW version is shown. If not then > DOWNLOAD HWINFO64 HERE <

Once HWINFO is open, look at the large window on the left side, expand motherboard, and find the ME area.
Inside that section is the ME Firmware version. Take note of the version. (ie. write it down or get a screenshot)

Once you have that, go to the thread linked below, and in the section "C.2" find and download the matching ME System Tools Package for your system.
(ie if ME FW version = 10.x get V10 package, if 9.0-9.1 get V9.1 package, if 9.5 or above get V9.5 package etc)
> DOWNLOAD " ME System Tools " packages HERE <

Once downloaded, inside you will find Flash Programming Tool folder, and then inside that a Windows or Win/Win32 folder (NOT x64).
Highlight that Win/Win32 folder, then hold shift and press right click. Choose "open command window here" (Not power shell! >> * See Registry file below *).

If you get an error, reply to this post with a screenshot of it, OR write down the EXACT command entered and the EXACT error given.

((If "open command window here" does not appear, look for the "Simple Registry Edit" below...))

Step #1
Now you should be at the command prompt.
You are going to BACKUP the factory un-modified firmware, so type the following command:
Command: " FPTw.exe -bios -d biosreg.bin "

>> Attach the saved "biosreg.bin ", placed into a compressed ZIP/RAR file, to your next post!!! <<

Step #2
Right after you do that, try to write back the BIOS Region dump and see if you get any error(s).
Command: " FPTw.exe -bios -f biosreg.bin "
^^ This step is important! Don't forget! ^^

If you get an error, reply to this post with a screenshot of it, OR write down the EXACT command entered and the EXACT error given.

Here is a SIMPLE REGISTRY EDIT that adds "Open command window here as Administrator" to the right click menu, instead of Power Shell
Double-click downloaded file to install. Reboot after install may be required
> CLICK HERE TO DOWNLOAD CMD PROMPT REGISTRY ENTRY <

If the windows method above does NOT work for you...
Then you may have to copy all contents from the Flash Programming Tool \ DOS folder to the root of a Bootable USB disk and do the dump from DOS
( DOS command: " FPT.exe -bios -d biosreg.bin " )

@gloobox - Can we FPT BIOS region on this model, if not, have you tested DXE volume dump/edit only?

Please don't send PM's for help on BIOS edits, I can't help with BIOS in PM's. Please make a thread and I will try to help as soon as I can - thanks!
If you appreciate my efforts and are willing to donate to help improve my hardware, gift cards work for me (Amazn, NuEgg, eBa) - send me a PM

@Lost_N_BIOS Sorry for the delay! I do see an FDO set of jumpers (2 of them). I'll try covering both of them and seeing what happens.

EDIT: It gives an error after I put the jumper on and rebooted a few times: "PDR Region does not exist. Error 28: Protected Range Registers are currently set by BIOS, preventing flash access. Please contact the target system BIOS vendor for an option to disable Protected Range Registers."

I have a BIOS programmer tool and clip if necessary to flash. The BIOS chip is very easily accessible on this board.

EDIT 2: Here is what fptw -i gives, in case needed:

Hi Brian,

You can also short the sense pins of each of the ports giving the error message, that's what I did on my board:

Sorry I havn't tested this mobo,but I think dumping bios region is OK but flashing modded bios could be stucked.

@brian105
Had you flash the modded bios and found the error28?
I suggest you try to flash with SPI programmer.
