running in MFS mode on the d710 nodes which have been set up for TPM booting. Major issues: The MFS image for TPM booting is 32bit while other Linux MFS images are 64bit. The TPM kernel only supports 4Gb of memory, does not support multi-processors. checkutils: Make sure the dd to be run is bit-with compatiable with the image. cpucheck: Check and handle missing cpu flags "physical id", "cpu cores", "siblings". Check and handle different Mhz format. diskcheck: Differnet blocks/sectors format. Rewrite getwspeed and getspeed funtions to handle dd and tdd compatibility and/or missing binaries. Give better error messages for timing speed failures.
