Gigabyte GA-Z77-D3H

Hi,
Make: Gigabyte
Model: GA-Z77-D3h v1.0
Original BIOS version F22: http://download.gigabyte.eu/FileList/BIO...3h_f22.exe
Preferably mod with Gigabyte SLIC 2.1
AcpiTbls.rw here: https://app.box.com/s/fgsvuudmzpsyrlsbfs10 <== sorry, this is for older BIOS version (F18).
AcpiTbls for version F22 here: https://app.box.com/s/nt33nzl2f1dxv80h66xw

Many thanks

Out of interest, how easy is it to mod a UEFI BIOS nowadays for SLIC insertion? I'd give it a go, but the various tools I've found are for older BIOSes and they don't recognise these new 8Mb ROMs...
