Re: [tboot-devel] Buying a machine that will actually work with TXT

I am using F.0B - the latest publically available for those systems. Tboot executes GETSEC[SENTER] and one of two things happens. 1. The system hangs during ACM execution and never re-enters tboot. 2. ACM completes and successfully re-enters tboot in SMX mode. Shortly after the system hangs while executing in tboot (seemingly at random spots from a tboot perspective). Thanks Ross -----Original Message----- From: Karthik .
