My understanding was that the fix was to force CLKRUN on before starting a LPC transaction for TPM. I guess the issues is blindly assuming that CLKRUN started out as off. It needs to remember the old setting and put it back, and hope against all hope there isn't another thread mucking with it. Guessing that on a system with a LPC connected superio controller for PS/2 that CLKRUN will be always high??? Jason
