What to name recovery BIOS ?

Hello,

My backup copy of my current BIOS reads as; Hewlet-Packard-F.14.rom

If I run the Phoenixtool on this rom, the recovery name results are;
A.BI?
C.BI?
B.BI?
What is the name of my recovery BIOS ?

A download of the current upgrade is SP51527.exe
How to extract the BIOS from the SP51527.exe file to use for USB recovery ?

Thanks
Fuzz
