Phoenix Bios unlock request for dell d600

[1creeperbomb]

Hey all!
I have a bios that I pulled of the dell d600 laptop.
This is the latest version already installed on the computer (A16).
The only problem is I tried to open up with Phoenix Bios Editor; However, it gave an error saying "No BCPs Found!"
I have modded a phoenix bios before and I already tried reading and backing up  the Bios rom file again but with no luck  
I have the rom file as an attachment below, and I was hoping you guys can figure it out.
Only thing I could think of was that the BIOS was made in 2005, so maybe its too old?

EDIT: I want to unlock the menu that allows you to change the total memory allocated to the onboard graphics as it as set to only 32 mb.

Alright so I did some research and found out that dell used to modify their phoenix BIOSs very heavily and as a result cannot be opened by PBE or Andy P's SLIC tool.

HOWEVER, There are some tools in existence that may possibly be able to decompile the Dell BIOS. The most common one mentioned was VCOM Sourcer Disassembler. Only problem is its old and works better on something like Windows 95 and warn it may not work on Windows NT. (No clue what it might do on Windows 7 or 10).

Anybody know more about this?
