0.0. READY FOR BOOT blank blank READY FOR BOOT(You may check board /revision from this step) Details please check Appendix
*When you turn the power on and can not see LED on, it indicates either power supply damage or LED went bad  

 POST STAGE-GURU CODE

POST (hex) DESCRIPTION SYMPTOM CAUSE ACTION
0.4. Detect memory-Auto-detection of DRAM size, type and ECC-Auto-detection of L2 cache (socket 7 or below) Power on -> Stop at 0.4. Memory fail Replace memory
8.3. Guru check ATX power supply ready signal Power on -> Stop at 8.3. 12V 4 pin plug disconnected or power supply damage Check 4 pin power plug or replace power supply
8.7. Check CPU core voltage Power on -> Stop at 8.7. 12V 4 pin plug disconnected or power supply damage Check 4 pin power plug or replace power supply
9.0. Complete μGuru initial processAWARD BIOS take over booting job 1. Power on -> Stop at 9.0.2. 0.0.-> 8.3. -> 9.0.  Award BIOS initial stop processing1. OC too high2.BIOS dead 1. Clear CMOS2.Restore default setting for BIOS3. Replace BIOS chip4. Send to RMA at last
9.3. De-Assert power on Power on -> Stop at 9.3. Power detect fail Replace power supply
9.F. μGuru force shutdown 1. Power on -> Stop at 9.F.2. 0.0.->8.3.->9.F. repeat 1. OC too high2. Power supply compatibility 1.Restore default setting for BIOS2. Replace with other power supply
F.0. Button reset Power on -> Stop at F.0. OC too high 1. Clear CMOS2. Restore default setting for BIOS
F.1. SoftMenu reset Power on -> Stop at F.1. OC too high 1. Clear CMOS2. Restore default setting for BIOS

*When you see guru code 9.9. or 9.F. on the LED, it indicates a normal shutdown.
*Under a normal condition, when you use soft turn off, you will also see 9.9. or 9.F.   ; you do not need to take any action.

Please change graphic card3. Change slot first or send to RMA at last4. Clear CMOS and   load BIOS default
25 Early PCI Initialization:-Enumerate PCI bus number.-Assign memory & I/O resource-Search for a valid VGA device & VGA BIOS, and put it into C000:0 00->C1->C3-> Stop at 25 BGA error Change graphic cards or unplug card and plug card back in again
26 1. If Early_Init_Onboard_Generator is not defined Onboard clockgenerator initialization. Disable respective clock resource to empty PCI & DIMM slots.2. Init onboard PWM3. Init onboard H/W monitor devices 00->C1->C3-> Stop at 26 BGA or Graphic card errors Change graphic cards or unplug card and plug card back in again
41 Initialize FDD device C3->25->26 -> Stop at 40 Floppy detect error Unplug FDD cable check error or check BIOS settings
50 Initialize USB 1. Power on -> Stop at 502.  00->C3->503. 2X-> 4X -> Stop at 50 USB boot fail(BBS issue)2. Incompatible USB devices Clear CMOS firstChange USB port or remove USB deviceDisable USB 5v stand by jumper
75 Detect & install all IDE devices: HDD, LS120, ZIP, CDROM … 4X->5X->Stop at 75 1. No IDE Device Power connected2. SATA or PATA device incompatible3. Device response time too long 1. Clear CMOS2. Check cable3. Check IDE device connector or change other PATA/ SATA devices4. Wait for a longer time (10~20  minutes) to detect device
7F Switch back to text mode if full screen logo is supported-If errors occur, report errors & wait for keys-If no errors occur or F1 key is pressed to continue: Clear EPA or customization logo 4X->5X->Stop at 7F Checksum ErrorBroken IDE cableLoad BIOS default Press Del bottom and load into BIOS, load optimized default. If problem remains the same, we suggest you send to RMA at last
