Choosing the correct bios for my Sapphire ATi 5770 card

[jrazor]

Hello to all,

Am just asking for some help in choosing the correct or most correct bios for my Sapphire card from the many available here on the TechPowerUp site.
It appears that this card has been "hacked" or re-flashed to make compatible with a Mac Pro 1,1 (the early 2006 model). Since I didn't do this and I would like to get it back to "as delivered" from Sapphire.
And since I didn't do this I do not have a copy of the standard BIOS (pre-changes) or even a copy of an Apple reference BIOS

Description is:
HD5770 1G GDDR5 PCI-E Dual DVI-I/HDMI/DP
Part No. is:
229-1E148-102SA
SKU # is:
11163-02

On the GPU (chip itself) it is stamped as:
"ATI LOGO"
1103
MADE IN TAIWAN
N3F929.00
214-0754034

Your help is appreciated

It may already have the correct BIOS, as that model card did come out for Mac.
