主板故障诊断卡 指示灯和声音功能速查表 Motherboard fault diagnosis card indicator and voice function lookup tables.Txt38 when the clouds covered the sky, the pessimist sees the "dark pressure to destroy" the optimist see is "energy-saving Linkai". In any adversity, as long as you keep optimistic, you can always find such a strange strawberry. Self checking alarm sound and its meaning: AMI BIOS 1 short memory refresh failed 2 short memory ECC more error checking 3 short system basic memory (first 64K) failed to check 4 short system clock error 5 short central processing unit (CPU) error 6 short keyboard controller error 7 short system real mode error, cannot switch to protection mode 8 short display memory error (indicating memory may be out of order) 9 short ROM BIOS tests and errors 1 long, 3 short memory errors (memory corruption, please replace) 1 long, 8 short display, test error (loose monitor data or unstable card insertion) Award BIOS 1 short system, normal boot machine 2 short routine error, please go to CMOS SETUP to reset incorrect options 1 long, 1 short, RAM or motherboard error 1 long, 2 short display errors (monitor or display card) 1 long 3 short keyboard controller error 1 long, 9 short, motherboard FlashRAM or EPROM error (BIOS damage) Keep ringing (long sound), memory unstable or damaged Keep ringing the power, the monitor is not connected to the display card Repetitive short circuit power supply No sound, no display power supply Phoenix BIOS 1 short system, normal boot machine 3 short system power on self check initialization (POST) failed 1 short, 1 short, 2 short motherboard error (motherboard damage, please replace) 1 short, 1 short, 3 short motherboards, batteries without electricity or CMOS damage 1 short, 1 short, 4 short, ROM, BIOS checksum error 1 short, 2 short, 1 short system, real-time clock problem 1 short, 2 short, 2 short DMA channel initialization failed 1 short, 2 short, 3 short DMA channel page register error 1 short, 3 short, 1 short memory channel refresh errors (problem range for all memory) 1 short, 3 short, 2 short, basic memory error (memory corruption or RAS setting error) 1 short, 3 short, 3 short basic memory errors (most likely memory corruption on the DIMM0 slot) 1 short, 4 short, 1 short, basic memory, an address error 1 short, 4 short, 2 short systems, basic memory (first 64K), there is parity error 1 short, 4 short, 3 short, EISA bus timing errors 1 short, 4 short, 4 short, EISA NMI error 2 short, 1 short, 1 short systems, basic memory (first 64K) failed to check 3 short, 1 short, 1 short, first DMA controllers or registers error 3 short, 1 short, 2 short, second DMA controllers or registers error 3 short, 1 short, 3 short primary interrupt processing register errors 3 short, 1 short, 4 short sub interrupt processing registers error 3 short, 2 short, 4 short keyboard clock problems, reset in CMOS Not Installed to skip POST 3 short, 3 short, 4 short display card, RAM error or no RAM, not fatal error 3 short, 4 short, 2 short display data lines loose or display card insertion instability or display card damage 3 short, 4 short, 3 short, no display card ROM BIOS 4 short, 2 short, 1 short systems, real time clock errors 4 short, 2 short, 2 short system start errors, CMOS settings improperly or BIOS damage 4 short, 2 short, 3 short keyboard controller (8042) in the Gate A20 switch is wrong, BIOS can not switch to protection mode 4 short, 2 short, 4 short protection mode, interrupt error 4 short, 3 short, 1 short memory errors (memory corruption or RAS setting error) 4 short, 3 short, 3 short systems, second clock errors 4 short, 3 short, 4 short, real time clock errors 4 short, 4 short, 1 short serial port (COM mouth, mouse mouth) fault 4 short, 4 short, 2 short parallel port (LPT port, print port) error 4 short, 4 short, 3 short digital coprocessor (8087, 80287, 80387, 80487) error Motherboard fault diagnosis card indicator function name lookup table lamp Lamp name, signal name Description RUN motherboard running, if the motherboard running, the lantern will continue to flash, the motherboard is not running, it is not bright CLK bus clock, regardless of ISA or PCI, as long as an empty board (no CPU, etc.) on the power supply, it should always light, or else CLK signal is bad. BIOS basic input and output, the motherboard running, reading operations on BIOS will flash. The IRDY main device is only ready to flash when it is ready to have IRDY signals, otherwise it is not lit. The OSC oscillation is the main vibration signal of the ISA slot, and the empty board should be energized frequently. Otherwise, the crystal oscillation circuit of the main board does not work, and there is no OSC signal. FRAME frame cycle PCI slot, there is a circular frame signal, the lights are shining, usually light. RST reset, RESET boot or press the RESET switch, bright half second extinguished is normal, if not out, often because of the motherboard on the reset pin, the error is connected to the acceleration switch, or the wrong short-circuit, or reset circuit is bad. The power board on the 12V power supply should be constantly bright, otherwise there is no voltage or the main board is short circuited. -12V power ibid. 5V power ibid. The -5V power is the same as above (only the ISA slot has this voltage). 3V3 power supply, this is PCI slot unique 3.3V voltage, empty board power should be always bright, and some motherboard PCI slot without 3V3 voltage, but not bright. Code analysis of mainboard fault diagnosis card CF Test CMOS R/W functionality. C0 The initial motherboard sets the initial value: - Disable shadow RAM - disable L2 cache (SURPER 7 architecture and late compatible Architecture) - detect basic chipset registers. C1 Detect memory: -Auto- detects the size, type, and DRAM of ECC (dynamic random access memory). -Auto- detects L2 cache (SURPER 7 architecture and later compatible Architecture) C3 Mapping BIOS encoding to DRAM. C5 Allow chipset to copy the BIOS to the address E000& F000 shadow RAM. 01 Positioning Xgroup encoding in memory addresses from 1000 to 0 03 Initializes Superio (super input, output), _Early (response), _Init (start) switch. 05 3. output the blank to the screen. 4. clear CMOS errors. 07 1. clear 8042 interface. 2. initialization 8042 interface self-test. 08 1. detection of special keyboard controller model Winbond, 977 series super I/O (input / output) chip. 2. allow keyboard interface. 0A 1. disable the PS/2 mouse interface Two Memory capacity is measured with double byte 64K packets. 2. writes the configuration for the AMD K5 processor. 4E 1.

(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, such as 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.

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. I don't know. Is that right? NOISE's original meaning is noise. I really don't know how to translate it Eighty-eight 1.CPU fault 2. motherboard failure Ninety-three Reads boot boot information whether it contains virus protected encoding Ninety-four 1. turn on the two level cache 2. boot speed of system boot. 3. the final initialization of the motherboard. 4. final initialization of power management. 5. clear screen & display summary.
