As BIOS usually has POST (Power On Self Test) program, then it will test every item step by step if no
failure takes place, however, if it detects a failure on a specific item, it will hang on there. Therefore,
BIOS could write timeout value to register 08h and start timer setup speech trigger event (register 09h),
then is BIOS test program started. Whenever the system is hang on specific item such as DRAM
testing, W83791D would say “DRAM test fails” after the timeout previously set at CR [08h]. On the
contrary, if DRAM test is ok, then BIOS could update the timeout value and proceed to the next test
program.
