Updating BIOS Command Lines

Microsoft Windows 10 (64-bit)

Hello All.

We are trying to update our BIOS on our systems without user interaction.

I understand how to use the HpqPswd.exe and the HPBIOSUPDREC.exe.

I can stop and reboot from happening but when we reboot the machine I'd expect the BIOS to automatcially flash by using the proper command line.

Here is what the help file will list.

HPBIOSUPDREC.exe [-s] [-pPasswordFile] [-fROMBINFile] [-a] [-h] [-b] [-?]

-s: Slient mode
-p: Specify encrypted file

-f: Specify ROMBINfile

-a: (Silent Mode Only) Always Flash, ignore version comparison
-r: Do not reboot
-h: Create HPTOOLS partition if needed
-b: Suspend BitLocker if needed
-?: Help

The command I'm passing wtih the -a I would expect it to automatcially flash without pompting the user with options.

HPBIOSUPDREC.exe -s -p "TempPass.bin" -f "N86_0113.bin" -a -h -b

So what happens is after the reboot just after post or during POST, it will prompt the user these four options.

 

  • Update Bios
  • Rollback Bios
  • Postpone
  • Cancel

I don't want the users to be prompted, I just want it to flash the BIOS at this point.  That is what I thought the "-a" was for.  Is there a way to just flash the BIOS without giving the users options?

I would expect that using '-a' could cause an INCORRECT update to be flashed into the BIOS, by NOT PREVENTING a "wrong" BIOS-file to be used.

 

The wording seems to imply that '-s' will NOT show the "prompting" messages.  Maybe.

Updating BIOS Command Lines

Hi,

 

please try the command line:

 

HPBIOSUPDREC.exe -s -pPassword-Path\password-file -fROM-Path\bin-file -r  -wmi

 

-s Silent mode. Runs without any user interaction or output.

-ppassword-file  Specifies encrypted password file created with the HpqPswd utility.

-fBIN-file Specifies the path to the .BIN image file

-r Requires -s. Do not reboot after flash

-wmi Force online flash, without using UEFI or HP Utility partition

 

 

This command line update the BIOS without any user interaction. It is tested within a MS SCCM task sequence and valid for BIOS Update Sofpaqs which are containing HPBIOSUPDREC.exe or HPBIOSUPDREC64.exe

 

Please be aware that the BIOS Update may run several minutes and may show a black screen for about a minute depending on the hardware platform

Updating BIOS Command Lines

Hi, how can I update an HP bios silently, without the bios recovery partition?  The -wmi option does not work.  The only way seem to be interactively.  I have to enter the password, but then on reboot I have to enter the password a second time at the bios screen.  Then it works, but it makes a new drive in windows.
