Hello,

After following the instructions in the readme to allow lax acpi_enforce_resources and use acpi_pm, I still can't seem to see the i2c bus of my mobo. I also can't figure out what pll my system has after looking at the chips on the board and searching the internet.

Can anybody confirm which pll I have and if it's supported? Thanks.
