BIOS POST Checkpoints This appendix lists the POST checkpoints of the notebook BIOS Table E-1 POST Checkpoint List Description Checkpoint 04h • Check CPU ID • Dispatch Shutdown Path Note: At the beginning of POST, port 64 bit (8042 system flag) is read to determine whether this POST is caused by a cold or warm boot If it is a cold boot, a complete POST is performed If it is a warm boot, the chip initialization and memory test is eliminated from the POST routine 08h • Reset PIE, AIE, UIE Note: These interrupts are disabled in order to avoid any incorrect actions from happening during the POST routine 09h • Initialize m1511 0Ah • Initialize m1513 0Bh • Initialize m7101 10h • DMA(8237) testing & initialization 14h • System Timer(8254) testing & initialization 18h • DRAM refresh cycle testing • Set default SS:SP= 0:400 1Ch • CMOS shutdown byte test, battery, and check sum Note: Several parts of the POST routine require the system to be in protected mode When returning to real mode from protected mode, the processor is reset, therefore POST is re-entered In order to prevent re-initialization of the system, POST reads the shutdown code stored in location 0Fh in CMOS RAM Then it jumps around the initialization procedure to the appropriate entry point The CMOS shutdown byte verification assures that CMOS 0Fh area is fine to execute POST properly • • 1Dh, 1Eh • Initialize default CMOS setting if CMOS bad Initialize RTC time base Note: The RTC has an embedded oscillator that generates 32.768 KHz frequency To initialize the RTC time base, turn on this oscillator and set a divisor to 32768 so that the RTC can count time correctly DRAM type determination BIOS POST Checkpoints E-1 Table E-1 POST Checkpoint List (Continued) Description Checkpoint 2Ch • • 128K base memory testing Set default SS:SP= 0:400 Note: The 128K base memory area is tested for POST execution The remaining memory area is tested later • KB controller(8041/8042) testing • KB type determination • Write default command byte upon KB type 24h • PIC(8259) testing & initialization 30h • System Shadow RAM 34h • DRAM sizing 3Ch • Initialize interrupt vectors 4Bh • Identify CPU brand and type 35h • PCI pass 40h • Assign I/O if device request 41h • Assign Memory if device requested 44h • Assign IRQ if device request 45h • Enable command byte if device is OK 51h • DownLoad keyboard matrix 50h • Initialize Video display 4Ch • ChipUp initialization for CPU clock checking 54h • Process VGA shadow region 58h • Set POST screen mode(Graphic or Text) • Display Acer(or OEM) logo if necessary • Display Acer copyright message if necessary • Display BIOS serial number 5Ch • Memory testing 5Ah • SMRAM test and SMI handler initialization 4Eh • Audio initialization 60h • External Cache sizing • External Cache testing(SRAM & Controller) • Enable internal cache if necessary • Enable external cache if necessary • Reset KB device 20h 64h • E-2 Check KB status Note: The keyboard LEDs should flash once Service Guide Table E-1 POST Checkpoint List (Continued) Checkpoint Description • Reset pointing device • Check pointing device 70h • Parallel port testing 74h • Serial port testing 78h • Math Coprocessor testing 80h • Set security status 84h • KB device initialization 7Ch • • Set KB led upon setup requests Note: If keyboard Number Lock is enabled, the NumLock LED (if present) should be turned on Enable KB device 6Ch • 88h • 89h • 90h • Display POST status if necessary • Change POST mode to default text mode 93h • Rehook int1c for quiet boot 94h • Initialize expansion ROM • Shadow I/O ROM if setup requests • Build up free expansion ROM table A4h • Initialize security feature A8h • Setup SMI parameters A0h • Initialize Timer counter for DOS use AAh • m1523 modify ACh • Enable NMI • Enable parity checking • Set video mode • Power-on password checking • Display configuration table • Clear memory buffer used for POST • Select boot device B0h FDD testing & parameter table
