POST коды Award BIOS (Version 4.51PG)

01Processor Test 1. 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.
02Processor Test 2. Read/Write/Verify all CPU registers except SS, SP, and BP with data pattern FF and 00.
03Initialize Chips. Disable NMI, PIE, AIE, UEI, SQWV, Disable video, parity checking, DMA, Reset math coprocessor, Clear all page registers, CMOS shutdown byte, Initialize timer 0, 1, and 2, including set EISA timer to a known state, Initialize DMA controllers 0 and 1, Initialize interrupt controllers 0 and 1, Initialize EISA extended registers.
04Test Memory Refresh Toggle. RAM must be periodically refreshed to keep the memory from decaying. This function ensures that the memory refresh function is working properly.
05Blank video Initialize keyboard. Keyboard controller initialization.
07Test CMOS Interface and Battery Status. Verifies CMOS is working correctly, detects bad battery.
08Setup low memory. Early chip set initialization, Memory presence test, OEM chip set routines, Clear low 64K of memory, Test first 64K memory.
09Early Cache Initialization. Cyrix CPU initialization, Cache initialization.
0ASetup Interrupt Vector Table. Initialize first 120 interrupt vectors with SPURIOUS_INT_HDLR and initialize, INT 00h-1Fh according to INT_TBL.
0BTest CMOS Checksum. RAM Test CMOS RAM Checksum, if bad, or insert key pressed, load defaults.
0CInitialize keyboard. Detect type of keyboard controller (optional), Set NUM_LOCK status.
0DInitialize Video Interface. Detect CPU clock. Read CMOS location 14h to find out type of video in use. Detect and Initialize Video Adapter.
0ETest Video Memory. Test video memory, write sign-on message to screen. Setup shadow RAM — Enable shadow according to Setup.
0FTest DMA Controller. BIOS checksum test. Keyboard detect and initialization.
10Test DMA Controller 1.
11Test DMA Page Registers. Test DMA Page Registers.
14Test Timer Counter 2. Test 8254 Timer 0 Counter 2.
15Test 8259-1 Mask Bits. Verify 8259 Channel 1 masked interrupts by alternately turning off and on the interrupt lines.
16Test 8259-2 Mask Bits. Verify 8259 Channel 2 masked interrupts by alternately turning off and on the interrupt lines.
17Test Stuck 8259’s Interrupt Bits. Turn off interrupts then verify no interrupt mask register is on.
18Test 8259 Interrupt Functionality. Force an interrupt and verify the interrupt occurred.
19Test Stuck NMI Bits (Parity/IO Check). Verify NMI can be cleared.
1ADisplay CPU clock.
1FSet EISA Mode. If EISA non-volatile memory checksum is good, execute EISA initialization. If not, execute ISA tests an clear EISA mode flag. Test EISA Configuration Memory Integrity (checksum & communication interface).

30Size Base and Extended Memory. Size base memory from 256K to 640K and extended memory above 1MB.
31Test Base and Extended Memory. Test base memory from 256K to 640K and extended memory above 1MB using various patterns. NOTE: This test is skipped in EISA mode and can be skipped with ESC key in ISA mode.
32Test EISA Extended Memory. If EISA Mode flag is set then test EISA memory found in slots initialization. NOTE: This test is skipped in ISA mode and can be skipped with ESC key in EISA mode.
3CSetup Enabled.
