CODE CODE 00 Award Award AMI AMI Code copying to specific areas is done. Passing control to INT 19h boot loader next. CPU is testing the register inside or failed, please change the CPU and check it. 01 Processor Test 1, Processor status (1FLAGS) verification. Test the following processor status flags: carry, zero, sign, overflow. The BIOS sets each flag, verifies they are set, then turns each flag off and verifies it is off. Test All CPU Registers Except SS, SP, and BP with Data FF and 00 Disable NMI, PIE, AIE, UEI, SQWV. Disable video, parity checking, DMA.
