• RAM subsystem • CMOS RAM subsystem and real time clock/calendar with battery backup When POST executes a task, it uses a series of preset numbers called checkpoints to be latched at port 80h, indicating the stages it is currently running. This latch can be read and shown on an external monitor - Acer AC100S | Acer AC100 Service Guide - Page 102
code is copied from ROM to lower system memory and control is given to it. BIOS now executes out of RAM. Both key sequence and OEM specific method is checked to determine if BIOS recovery is forced. Main BIOS checksum is tested. If BIOS recovery is necessary, control flows to checkpoint E0. See - Acer AC100S | Acer AC100 Service Guide - Page 103
