Bios Mods -The Best BIOS Update and Modification Source

HI,
I hope this is the right place for this post (possibly not)
I have an ASUS CP6230-8 which was shipped with Windows 8 (using the BIOS Embedded Product ID)
The problem with this BIOS is that is doesnt have a Windows 7 compatible SLIC Table.
Running SLIC 3.2 toolkit the SLIC Table shows nothing in the table.
The Model of the PC:-
Asus-cp6230-desktop-cp6230-uk007s
Previous Models would let WIndows 7 install, but the previous Bioses will not flash - this version of PC uses *.CAP Bios roms, and not ROM or BIN.
It is an AMI BIOS with UEFI.
Any Help would be appreciated. - even if someone could tell me how to add a SLIC table.

Many Thanks.

Apologies for double posting - I'm uncertain where to post.

I guess, due to the amounts of viewers this post recieves in such a short time, there are many others wanting to install Windows 7 onto one of these PCs.
