there are two programms you need to turn on PAT.the first is WPCREDIT the second is PCITree.
At www.x86-secrets.com you see the instruction.
Set with WPCREDIT dev0:Bus0:Func:0 the register F4/Bit1 to 1.
then the hidden dev6:bus0:func:0 will be avable in WPCREDIT!
Then set in dev6:bus0:func0 the register 04 and 05/Bit1 to 1.
so the hidden MMR region in the high memory aera is accessable.
Then take PCITree and go to the dev6:bus0:func0 and look at register 10,11,12,13,14 there is the base address FECF0000 of the high memory area and edit the MMR like www.x86-secrets.com show and you have enable PAT.
Then turn off access of dev6 and MMR and write in a 0 where you befor have enter a 1 Bit.
