HP Compaq Elite 8100 Bios Modding Help

[myrb26]

Hello,
Could i please have some help with bios modding on a hp compaq elite 8100. Im not sure where to start because 1) im new here 2) I have found nothing on google about the computer and bios mods.

The pc has a i3 530, 4x2gb 1333mhz samsung ram and a amd radeon 8490.
Everything else should be here -> https://support.hp.com/au-en/document/c02030592
The bios/update is here(hope it helps) -> https://support.hp.com/au-en/drivers/sel...pc/4098436
I would provide more info if i knew what was needed. Im not afraid of bricking the motherboard because they are only $20 

Thank you!

EDIt:  
Ran BIOS Backup ToolKit v2.0 and dumped the .rom file, i have also extracted the .bin bios from hp.
The confusing bit is that the bios backup tool says that the type os "Others BIOS /ACPI 1.0" while bios info tool v1.4 says that the bios is made by Compaq computer corp.
I have also dumped a rom file from a different pc and bit says that the bios is by American Megatrends.
Hope that this helps a bit.

The Hewlet-Packard...rom is the bios dump 
The 7H1_0113.bin is what i extracted from the bios updater.
