Initialize BIOS, POST, Runtime data area. Also initialize BIOS modules on POST entry and GPNV area. Initialized CMOS as mentioned in the Kernel Variable "wCMOSFlags. " Check CMOS diagnostic byte to determine if battery power is OK and CMOS checksum is OK. Verify CMOS checksum manually by reading storage area. If the CMOS checksum is bad, update CMOS with power-on default values and clear passwords. Initializes data variables that are based on CMOS setup questions. Initializes both the 8259 compatible PICs in the system Initializes the interrupt controlling hardware (generally PIC) and interrupt vector table. Initialize CH-0 as system timer. Install the POSTINT1Ch handler. Enable IRQ-0 in PIC for system timer interrupt. Traps INT1Ch vector to "POSTINT1ChHandlerBlock. " Initializes the CPU. Program the keyboard controller command byte is being done after Auto detection of KB/MS using AMI KB-5. Initializes the 8042 compatible Key Board Controller. Detects the presence of Keyboard in KBC port. Testing and initialization of different Input Devices. Traps the INT09h vector, so that the POST INT09h handler gets control for IRQ1.
