I am not to sure how to check (a bit of a novice unfortunately). Does any of this information help?
I didn't want to flood the page so I hope this pastebin will help - http://pastebin.com/7kSZkytf
edit: If it helps at all I installed everything via multi-beast. (lol @ multifail auto correct)
edit 2: After more playing around I found out how to view and edit my dsdt.aml file. I believe it is set to 12 as can be seen here:
Method (_DSM, 4, NotSerialized)
{
If (LEqual (Arg2, Zero))
{
Return (Buffer (One)
{
0x03
})
}
Return (Package (0x06)
{
"layout-id",
Buffer (0x04)
{
0x0C, 0x00, 0x00, 0x00
},
"hda-gfx",
Buffer (0x0A)
{
"onboard-1"
},
"PinConfigurations",
Buffer (Zero) {}
