Acer Aspire 5741 with Packard Bell EasyNote TM98 mb

Hi,

I got used EasyNote TM98 mb (BIOS V1.10) for my (broken) Acer Aspire 5741 laptop.
Mb is same but bios isn't (obviously). Just Installed Win7 x64 and used Acer drivers, everything works fine except FN-keys (installed LaunchManager Dritek).

Can I flash original Acer bios (V1.15 Winflash_NEW70115) to Packard Bell EasyNote TM98 mb?
