7C Generate and write contents of ESCD in NVRam. 84 Log errors encountered during POST. 85 Display errors to the user and gets the user response for error. 87 Execute BIOS setup if needed / requested. Check boot password if installed. 8C Late POST initialization of chipset registers. 8D Build ACPI tables (if ACPI is supported) 8E Program the peripheral parameters. Enable/Disable NMI as selected 90 Initialization of system management interrupt by invoking all handlers. Please note this checkpoint comes right after checkpoint 20h A1 Clean-up work needed before booting to OS. Chapter 4 170 Checkpoint Description A2 Takes care of runtime image preparation for different BIOS modules. Fill the free area in F000h segment with 0FFh. Initializes the Microsoft IRQ Routing Table. Prepares the runtime language module. Disables the system configuration display if needed. A4 Initialize runtime language module. Display boot option popup menu. A7 Displays the system configuration screen if enabled. Initialize the CPU's before boot, which includes the programming of the MTRR's. A9 Wait for user input at config display if needed. AA Uninstall POST INT1Ch vector and INT09h vector. AB Prepare BBS for Int 19 boot. Init MP tables. AC End of POST initialization of chipset registers. De-initializes the ADM module. B1 Save system context for ACPI. Prepare CPU for OS boot including final MTRR values. 00 Passes control to OS Loader (typically INT19h). 171 Chapter 4 DIM Code Checkpoints Checkpoint Description 2A Initialize different buses and perform the following functions: Reset, Detect, and Disable (function 0); Static Device Initialization (function 1); Boot Output Device Initialization (function 2). Function 0 disables all device nodes, PCI devices, and PnP ISA cards. It also assigns PCI bus numbers. Function 1 initializes all static devices that include manual configured onboard peripherals, memory and I/O decode windows in PCI-PCI bridges, and noncompliant PCI devices. Static resources are also reserved. Function 2 searches for and initializes any PnP, PCI, or AGP video devices. 38 Initialize different buses and perform the following functions: Boot Input Device Initialization (function 3); IPL Device Initialization (function 4); General Device Initialization (function 5). Function 3 searches for and configures PCI input devices and detects if system has standard keyboard controller. Function 4 searches for and configures all PnP and PCI boot devices. Function 5 configures all onboard peripherals that are set to an automatic configuration and configures all remaining PnP and PCI devices. ACPI Runtime Checkpoints Checkpoint Description AC First ASL check point. Indicates the system is running in ACPI mode. AA System is running in APIC mode. 01, 02, 03, 04, 05 Entering sleep state S1, S2, S3, S4, or S5. 10, 20, 30, 40, 50 Waking from sleep state S1, S2, S3, S4, or S5. Boot Block Beep Codes Number of Beeps Description 1 No media present. (Insert diskette in floppy drive A:) 2 'AMIBOOT.ROM' file not found in root directory of diskette in A: 3 Insert next diskette if multiple diskettes are used for recovery 4 Flash Programming successful 5 File read error 7 No Flash EPROM detected 10 Flash Erase error 11 Flash Program error 12 'AMIBOOT.ROM' file size error 13 BIOS ROM image mismatch (file layout does not match image present in flash device) POST BIOS Beep Codes Number of Beeps Description 1 Memory refresh timer error. 3 Base memory read/write test error 6 Keyboard controller BAT command failed 7 General exception error (processor exception interrupt error) Chapter 4 172 Number of Beeps Description 8 Display memory error (system video adapter) Troubleshooting POST BIOS Beep Codes Number of Beeps Troubleshooting Action 1, 3 Reseat the memory, or replace with known good modules. 6, 7 Fatal error indicating a serious problem with the system. Consult your system manufacturer. Before declaring the motherboard beyond all hope, eliminate the possibility of interference by a malfunctioning add-in card. Remove all expansion cards except the video adapter. • If beep codes are generated when all other expansion cards are absent, consult your system manufacturer's technical support. • If beep codes are not generated when all other expansion cards are absent, one of the add-in cards is causing the malfunction. Insert the cards back into the system one at a time until the problem happens again. This will reveal the malfunctioning card. 8 If the system video adapter is an add-in card, replace or reseat the video adapter. If the video adapter is an integrated part of the system board, the board may be faulty. 173 Chapter 4 Chapter 4 174 Chapter 5 Jumper and Connector Locations Mainboard Top View 21346789101112151314161718195 Item Description Item Description 1 Iinverter conn 11 Audio conn 2 power conn 12 light foot conn 3 LCD conn 13 light pipe conn 4 GPU FAN conn 14 B-CAS conn 5 CPU FAN conn 15 USB conn 6 camera conn 16 Speaker conn 7 card reader c...
