Disable the PCI& DIMM slot that is not in use. 5. early PCI sets initial values: - enumerates the PCI bus serial number. Allocating memory - input / output resources. - look for a valid video graphics adapter device & video graphics adapter BIOS, and put it in C000:0. Twenty-six 1. overclocking error (empty CMOS) 2. not installed graphics or graphics card damage 3. graphics card version and graphics card BIOS version does not match Twenty-seven Initialize INT 09 buffer. Twenty-nine 1. allocate the CPU internal MTRR (P6&PII) to 0-640 memory addresses. 2. initializes the Pentium of class CPU APIC. 3. set the COMS according to the earlier motherboard. Example: the IDE controller on the motherboard. 4. test CPU speed. 5. activate the display adapter BIOS. 2D 1. initialization multi language support. 2. displays information on the screen, including the BIOS name, CPU type, and CPU speed. Thirty-three Reset the keyboard except for the Winbond 977 series super input / output chip. 3C Check port 8254 3E The detection channel 1 is interrupted by a 8259 port with BIT as the data unit. Forty The detection channel 2 is interrupted by a 8259 port with BIT as the data unit. Forty-three The functionality of the 8259 was detected. Forty-seven Initializes the EISA slot Forty-nine 1. detects memory capacity with double byte 64K packets. 2. writes the configuration for the AMD K5 processor. 4E 1. MTRR allocation of M1 processors 2. initializes the two level cache for the P6 level CPU & the cache range that the program can use. 3. initializes the APIC value of the P6 level CPU. 4. on the MP platform, each cache is allowed to adjust the cache in a smaller range to prevent conflicts. Fifty Initializes the universal serial bus (USB) Fifty-two Check all memory (clear all extended memory to 0) Fifty-five Displays the CPU sequence number (multiprocessor platform) Fifty-seven 1. shows PnP LOGO. 2. initializes early ISA PnP. - assign CSN to each ISA PnP device. Fifty-nine Initializing hardware virus protection. 5B (optional) display relevant information when using floppy disk drive into AWDFLASH.EXE (optional) 5D 1. initialization Init (start) _ Onboard (board) _ SuperI/O switch. 2. initializes the Init_ Onbaord_ AUDIO audio switch. Sixty When all is complete, go to the settings interface; i. e. until the PSOT self-test completes, and the user can access the CMOS settings interface. Sixty-five Initializes the PS/2 interface mouse. Sixty-seven Provide memory information for the activation system: INT, 15h, ax=E820h Sixty-nine Open L2 cache (two level cache) 6B The motherboard is set and associated with the description information of the components installed on the system. 6D 1. allocate resources for ISA PnP devices. 2. automatically assign port values to the COM port when the system component is set to "AUTO". 6F 1. initialize floppy disk controller. 2. load floppy drive failed 40: hardware. (there is a floppy drive in BIOS, but no hardware is installed) Seventy-three (optional) whether to enter AWDFLASH.EXE: - when AwdFlash is found in the floppy drive. - when Alt+F2 is pressed. Seventy-five Detect & install all IDE devices: HDD (hard disk), LS120, ZIP (these two are special drives), USB, flash, etc., CDROM (CD-ROM) Seventy-seven Detect serial port (COM port, SATA) and parallel port (printer, IDE port). 7A Check & install the co- processor (SORRY, I can't see it here) 7F 1., when you support full screen image graphics, convert to text mode. If an error occurs, report an error and wait for the keyboard input. If there is no error, or when the F1 button is pressed continue: Show / hide boot screen or self set graphic images. Eighty-two 1. start the power management function of the motherboard. 2. restore the power star's boot screen (not the full screen boot screen) 3. if you set the boot password, you will need to access the password. Eighty-three Save all settings to CMOS. Eighty-four Initializes the ISA PnP boot device. Eighty-five 1. final initialization of universal serial bus. 2.. Network personal computers: building SYSID structures. 3. press the power switch and return to this mode. 4. set up memory for ACPI (Advanced Power Management) support. 5. wake up the ISA adapter ROMs. 6. allocation of PCI devices to IRQs (system interrupt mode). 7. initialize APM 8. clear IRQs conflicts.
