NOTE: EISA POST codes are typically output to port address 300h. ISA POST codes are output to port address 80h. Description
OEM Specific-Cache control cache Processor Status (1FLAGS) Verification. Tests 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. Read/Write/Verify all CPU registers except SS, SP, and BP with data pattern FF and 00. RAM must be periodically refreshed to keep the memory from decaying. This function ensures that the memory refresh function is working properly. First block memory detect OEM Specific-Test to size on-board memory. Early chip set initialization Memory presence test OEM chip set routines Clear low 64K of memory Test first 64K memory. OEM Specific- Board Initialization OEM Specific- Turn on extended memory Initialization Cyrix CPU initialization Cache initialization OEM Specific- Display/Video Switch Handling so that Switch Handling display switch errors never occurs OEM specific- Early shadow enable for fast boot External cache size detection CMOS checkup If interrupt occurs in protected mode. If unmasked NMI occurs, display Press F1 to disable NMI, F2 reboot. To program chipset from defaults values E1- Page 1, E2 - Page 2, etc. Chipset defaults program Turn Off Chipset And CPU test
