Registers in CPU tested with data patterns, error flags are set, verified and reset Checksums are performed on high and low BIOS chips Test timer channels 0-2 then the memory refresh signal.Initialize timer if tests are passed. Check the 8254 chip Walking bit and address collision tests are performed on the first 64K of memory. Check for a bad memory chip or address line The the CPU cache controller and memory Initialize the video adapter. If EGA.VGA is present, wait for the adapter to finish internal diagnostics. Check for adapter or improper setup if a failure occurs Bit patterns writtento all DMA controller registers, including page registers, and verifies the patterns written. If the tests pass the registers are reset and the controller initialized Test mask register of master and slave interrupt controllers. Generate interrupt and monitor CPU to test success. Failure is normally down to the PIC but the interrupt test uses the BIOS clock (interrupt) and the RTC, so check thosealso Perform several tests on the 8042 keyboard controller then send a series of interrupt request commands via the 8259 PIC Test the HP-HIL (Hardware Interrupt Level) controller with data patterns and verify it Perform a checksum on the standard and extended CMOS RAM area. Perform a register test and check byte 0D to determine power status. Check the CMOS extended CMOS RAM or batteryrespectively if a failure occurs Search for diagnostic tool used in manufacturing and run predetermined tests if found. Otherwise continue POST Test RAM between 64K and 640K with several pattern test. The bit failure and bank can be determined by the displayed hex code Test extended memory found. Bank and failing bit displayed by the hex code Test the RTC portion of the CMOS chip Test keyboard controller.Initialize keyboard if no errors found Test and initialize floppy controllers and drives found. Check specific errors with the displayed hex code. Check for correct setup or defective CMOS chip or defective battery Test NPU registers and interrupt request functions Test interface between CPU and system at different speeds. Check for incorrect clock setting for system peripherals or a bad CPU orclock generator chip Test and initialize serial and parallel ports. Failure here will not halt the POST. The Vectra RS BIOS does not test the parallel port Initialize the BIOS vector table, standard and extended CMOS data areas and any adapter ROM's present. Then call Int 19 boot loader and give control to it. Failures past this point usually point to the hard drive or corrupt bootloader code
