Device (TPM), help with removing its code from DSDT
Just found out that the TPM device is a rarely used security feature that is part of some Intel chipsets, and doesn't seem to be used at all by OSX/Apple. TPMM and TPMA look to be directly related to TPM, so I see no problem in removing…

TIP: If you get PANIC with no CLUES
“Thanks for the tip, I will have to give it a try, as I've been having the occasional 'double kernel panic' randomly show up on my legacy 10.6.4 build. My BT MagicMouse also freezes up every once in a while, so who knows maybe this will fix …”

Beware using other people's DSDT
“I created my first DSDT file from Windows, using DSDTse for Win, while I still had AHCI disabled. Then after enabling AHCI, disabling the serial and parallel ports in the BIOS, plugging in and turning on all eSata drives I generated another…”

Device (TPM), help with removing its code from DSDT
“I would definitely say it has to remain, as the other values are referenced throughout the DSDT. What I'm worried about is with the removal of TPME, the KBEP and MSAR references will not point to their proper values.”

Device (TPM), help with removing its code from DSDT
“Thanks for the effort, but I've already done that to test it out. What I would like to know is what effect leaving the TPME value in IndexField may have down the road. But it would be nice to know why the OperationRegion(TPMM...) needs to b…”

Device (TPM), help with removing its code from DSDT
“There's no need to remove it, it doesn't nothing. Just make sure it's disabled in your bios and remake the dsdt and it should gone then. I did a thorough search of the DSDT, and only the above code and variable/constant is referenced by it.…”
