Leaves all RAM below 1MB Read-Write including E000 and F000 shadow areas but closing SMRAM. Give control to BIOS POST (ExecutePOSTKernel). D4 D5 D6 D7 DA 32 The POST code checkpoints are the largest set of checkpoints during the BIOS pre-boot process. The following table describes the type of checkpoints that may occur during the POST portion of the BIOS: Checkpoint 03 Description Disable NMI, Parity, video for EGA, and DMA controllers. Initialized CMOS as mentioned in the Kernel Variable 04 “wCMOSFlags. ” Check CMOS diagnostic byte to determine if battery power is OK and CMOS checksum is OK. If the CMOS checksum is bad, update CMOS with power-on default values and clear passwords. 05 06 Initializes both the 8259 compatible PICs in the system Initializes the interrupt controlling hardware (generally PIC) and interrupt vector table. Traps INT1Ch vector to “POSTINT1ChHandlerBlock. ” 08 Initializes the CPU. Program the keyboard controller command byte is being done after Auto detection of KB/MS using AMI KB-5. Early CPU Init Start — Disable Cache - Init Local APIC Set up boot strap proccessor Information Set up boot strap proccessor for POST Enumerate and set up application proccessors Re-enable cache for boot strap proccessor Early CPU Init Exit Initializes the 8042 compatible Key Board Controller. Traps the INT09h vector, so that the POST INT09h handler gets control for IRQ1. Uncompress all available language, BIOS logo, and Silent logo modules. Detects and initializes the video adapter installed in the system that have optional ROMs. Activate ADM module. C0 C1 C2 C5 C6 C7 0A 0B 0C 0E 33 33 37 38 39 3A 3B 3C 40 Initializes the silent boot module. Displaying sign-on message, CPU information, setup key message, and any OEM specific information. Detect different devices (Parallel ports, serial ports, and coprocessor in CPU, etc. ) successfully installed in the system and update the BDA, EBDA, etc. 50 52 60 75 78 7A 7C 84 85 87 8C 8D 8E 90 A0 A1 A2 Programming the memory hole or any kind of implementation that needs an adjustment in system RAM size if needed. Build ACPI tables (if ACPI is supported) Program the peripheral parameters. Enable/Disable NMI as selected Late POST initialization of system management interrupt. Disables the system configuration display if needed. A4 A7 A8 A9 AA AB AC B1 00 Initialize runtime language module. Initialize the CPU’s before boot, which includes the programming of the MTRR’s. Passes control to OS Loader (typically INT19h). 34 SAT 2. 13 SATAII Hard Disk Setup Guide Before installing SATAII hard disk to your computer, please carefully read below SATAII hard disk setup guide. Some default setting of SATAII hard disks may not be at SATAII mode, which operate with the best performance.
