Bios Mods -The Best BIOS Update and Modification Source

BIOS Mod Request

Could someone please help me with that?
I have modded many BIOSes before, but this one is out of my league it seems.
It does require an advanced knowledge of BIOS Modding...
Who is up to this challenge?

-Manufacturer: HP ProLiant ML110 G7 E3-1240 1P 8GB RPS Server/S-Buy
-Model Number: 656766-S01
-Bios revision: J01
-ROM Size: 0x7F (8192KB)
-Bios Type: HP ROMpaq (UEFI???) Not Sure
-Bios Download Link: ftp://ftp.hp.com/pub/softlib2/software1/...P53226.exe
-RW Everything Report Download Link: http://www.datafilehost.com/download-848be824.html

I have tried the following:
1. Searched for existing BIOS Mod and found nothing
2. Read up on modding HP ROMPAQs
3. I tried to unpack a bios file using a ROMPAQ but was unable to load output file using:
a) phoenixtool195.zip
b) awardtool152
c) amitool162
PLEASE HELP adding HP Server Windows 2008R2 SLIC2.1 into this BIOS.
Also what tool would you recommend to use for flashing since ROMPAQ.EXE checks for header signatures.

Thank you,

Anton
