results of the test are contained in the general-purpose register
EAX. If EAX contains 0000_0000h, then BIST was successful. If
the contents of EAX are non-zero, the BIST failed. The internal
resources tested during BIST include the following:
■
L1 instruction and data caches
■
L2 unified cache (models 9 and D only)
■
Instruction and data translation lookaside buffers (TLBs)
