TROUBLE SHOOTING FOR ERROR MESSAGES
The following information will present the resolution of trouble encountered as well as the error messages. Adjust the system following the messages below and make sure all the components & connectors are in proper position and firmly attached. If the error still remains, contact with your distributor for maintenance.
POST BEEP :
There are two kinds of beep codes in BIOS. One code indicates that a video error has occurred and the BIOS cannot initialize the video screen to display any additional information. This beep code contains a single long beep followed by three short beeps. The other code indicates that DRAM error has incurred. This beep code appears a single long beep repeatedly.
CMOS BATTERY FAILURE :
When the CMOS battery is out of work or has run out, the user has to replace it with a new battery same as the old one.
CMOS CHECKSUM ERROR :
When the battery runs weak, CMOS will be corrupted. Check the battery and change a new one when necessary.
DISPLAY SWITCH IS SET INCORRECTLY:
Display switch on the motherboard can be set to either monochrome or colour, which indicates the switch is set to a different setting from the indicated in Setup. Determine which setting is correct, and then either turn off the system and change the jumper, or enter Setup and change the video selection.
DISK BOOT FAILURE:
When boot device isn’t available, insert a system disk into Drive A and press < Enter >. Make sure both the controller and cables are all in proper positions, also make sure the disk is formatted correct device. Then reboot the system.
DISKETTE DRIVES OR TYPES MISMATCH ERROR :
If the diskette drive type is different from CMOS, run setup and correct it .
ERROR ENCOUNTERED INITIALIZING HARD DRIVE :
When hard drive can’t be initialized, make sure the adapter is installed correctly and all cables are properly and firmly attached. Also be sure the correct hard drive type is selected in Setup.
ERROR INITIALIZING HARD DISK CONTROLLER:
When error occurs, be sure the cord is exactly installed in the bus and the correct hard drive type is selected in Setup. Besides that, check whether all of the jumpers in the hard drive are set correctly.
FLOPPY DISK CONTROLLER ERROR OR NO CONTROLLER PRESENT:
When fail to find or initialize the floppy drive controller, check whether the controller in proper station. If there are no floppy drive installed, Ensure the Diskette Drive selection in Setup is set to NONE.
KEYBOARD ERROR OR NO KEYBOARD PRESENT :
When it happens, make sure keyboard properly attached and no keys being pressed during booting. If you are purposely configuring the system without a keyboard, enter <ADVANCED CMOS SETUP>and choose <Absent>at the item<System Keyboard>, BIOS will ignore the missing keyboard and continue the booting.
