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.

storage capacity, users can select many W55FXX to connect with each other. The maximum capacity could be up to
16Mbit. Following is the connection chart of W55FX with W83791D.
For example: As BIOS usually has POST (Power On Self Test) program, then it will test every item step by
As is described previously that the W83791D has connectable W55FXX to store voice data. To expand the
