Hi:

Updating the BIOS in that model is a two-step process if you want to go to the latest version.

First, you have to update the BIOS to version 2.99.

- Customers MUST flash this BIOS first, before flashing to the v03.xx versions.

https://ftp.hp.com/pub/softpaq/sp73001-73500/sp73099.exe

Then you can update to v3.08.

https://ftp.hp.com/pub/softpaq/sp95501-96000/sp95971.exe 

Here is the easiest way to update the BIOS without being in Windows.

Run sp73099.

An info page will open.   Read the instructions under the F10 BIOS setup flash method.

                                     Startup Menu / F10 Setup BIOS Flashing

The HP Business Desktop systems provide a BIOS upgrade option through both the Startup Menu and the F10 Setup utility using the "Flash System ROM" feature.  Reboot the PC and press the Escape key to display the Startup Menu. Use the arrow keys to select Utilities, and then select the Flash System ROM option. Alternatively, reboot the PC and press F10 to access the BIOS Setup utility. In the File menu, select Flash System ROM.  Either method requires that removable media be present (USB storage or data CD) that contains the BIOS binary image file in the root directory. The binary image file can be found in the DOS Flash folder and is named xxx_MMmm.bin where "xxx" is the BIOS family, "MM" is the major version number, and "mm" is the minor version number.  To create a CD for updating the BIOS, use a blank CD-R or CD-RW disk on a system with a CD-RW or DVD+RW drive, and write the binary to the disk using any CD-burning software (Windows 7 and Vista support burning data CDs without additional software). If a BIOS Setup password has been set, the password will be required before being able to access the "Flash System ROM" menu. The user is notified when the process is completed.  The new BIOS code will not take effect until the PC is restarted.

View Contents of DOS Flash Folder

Here's what you do...

Get a USB flash drive.   Format it with the FAT32 file system.

Click on the View Contents of DOS flash folder that is at the bottom of that information page under the F10 Setup BIOS flash section.

Copy all of the files in that folder to the USB flash drive.  Just the files, not the folder.

Restart the PC.

Press/Tap the ESC key to get the menu of options.

Select the F10 setup option and press the enter key.

Select the File tab>Flash system ROM command.

Select the USB flash drive.

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

Follow the onscreen instructions to update the BIOS.

Then repeat the same process with sp95971 after you remove the BIOS files from v2.99 from the flash drive.

You just may want to format the flash drive again and start fresh.
