Hi:

The latest BIOS update for your PC is v3.61.

Here is the link to the update...

https://ftp.hp.com/pub/softpaq/sp84001-84500/sp84161.exe 

The Windows based flash was written to be run on Windows 7, and you are running W10, so what you should do is to update the BIOS using the F10 Setup BIOS flash method so you can update the BIOS without being in Windows.

Run the above file.   An info page will open and will provide several methods to update the BIOS.

Read the instructions under this section...

                                                     F10 Setup BIOS Flashing

The HP Workstation system supported by this Softpaq provides a BIOS upgrade option through F10 setup using the “Flash System ROM” feature.  Reboot the PC and press F10 to enter setup.  In the File menu, select the “Flash System ROM” item.  This flash utility will present the user with the option to select the media containing the BIOS image file (XXX_MMmm.bin).  The binary image file is contained in the DOS Flash directory and is named XXX_MMmm.bin where "XXX" is the abbreviated BIOS family, "MM" is the major version number, and "mm" is the minor version number.  F10 ROM based flash can accept the binary file from the root directory of any removable media such as USB or CD. On the Z800, Z600, and Z400 platforms the floppy diskette is no longer supported as a BIOS flash device as the ROM image is too large to fit on the floppy disks.  The BIOS CD Media file, included in this Softpaq, should be used to create a BIOS image CD.  When flashing with F10 ROM based flash, the CD media must be El-Torito compatible.  The user is prompted when the process is completed.  The new BIOS code will not take effect until the PC is rebooted.

View Contents of DOS Flash Folder

Here's what you do...

Get a USB flash drive

Format it with the FAT32 file system.

Copy all of the files listed under the View Contents of the DOS flash folder link.  Just the files, not the folder.

Restart the PC.  Press the F10 key to get access to the BIOS.

Select the File tab>Flash system ROM command.

Select the USB flash drive.

The PC will 'see' the BIOS files on the flash drive.

Follow the onscreen instructions to update the BIOS.
