Bios post code d4 Can't boot. - SIS741GX-MN Motherboard

The beep codes are BIOS specific and so you will need to pay attention to the post as your computer boots and note what BIOS it has. Then you can go to a website such as http://www.bioscentral.com/beepcodes/phoenixbeep.htm and look up the codes for your specific installation. On the right hand side you can select different types of BIOS.

Error Code: 0280 Previous boot incomplete - Default configuration used

Message Meanings : Previous POST did not complete successfully. POST loads default values and offers to run Setup. If the failure was caused by incorrect values and they are not corrected, the next boot will likely fail. On system with control of wait states, improper Setup settings can also terminate POST and cause this error on the next boot. Run Setup and verify that wait-state configuration is correct. This error is cleared the next time the system is booted.

What does the above mean ??? If the BIOS does not see a particular device loading ( like Hard Drive ) Try bringing up the Bios setting F-2 and reset to default. Hope this helps


BBBB
If one of the BIOS settings is incorrect or if the system is looking for a particular ggggg

You should always let someone who is a repairman add object's to your Motherboard

.Abit did not add the BIOS post to the manual.

Watch the BIOS post, most all motherboards have the hot-key menu at BIOS post.

If for some reason the hot-key is not reported on BIOS post, then you hit the DELETE key and enter the BIOS, Advanced BIOS Features Setup Menu and set what hardware you want to boot first, under Hard Disk Boot Priority, set First Boot Device

I do not see anything in the manual about LEDs for D1-D4
Super Micro Computer Inc Products Motherboards Xeon Boards X5DP8 G2 .

However if the motherboard is not posting it could be the RAM. One continuous long beep means that there is no memory detected (D1-D4 may refer to the dimm slots 1-4). You can try booting off of a single stick of RAM, and try different dimm slots to get the motherboard to post.

The D4 light is coming on to tell you that there is one or more fault codes set in your transmission control module. The only way to retrieve codes on the 1995 models is to read "Flash Codes" output by the D4 light. (See instructions below)

RETRIEVING FLASH CODES USING THE D4 LIGHT
If fault codes are present, the D4 light will "blink" when the ignition is turned to the RUN position and will remain on at all times when the engine is running.
To retrieve the flash codes, turn the ignition switch off.
Install a jumper wire between the service check connector terminals.
The service check connector is a gray, 2-pin connector located on the PCM/TCM cover under the passenger side of the instrument panel. (See picture below)

CAUTION: DO NOT use the 3-pin located next to the service check connector.

Installing the jumper will place the PCM/TCM in diagnostic test mode.
Turn the ignition to the RUN position. Codes will be output by blinking the D4 light.
Note the number of blinks from the D4 light. A short blink indicates a single digit flash code. A long blink equals 10 short blinks. For instance one short blink indicates code 1. One long blink and four short blinks indicates code 14. If there is more than one fault code, they will be output one at a time from the lowest numbered code to the highest numbered code. It is recommended that you read the code or codes several times to make sure that you are reading it correctly.

Once you have retrieved the fault code(s) re-post your question and include the information for what codes you have and someone can then help you locate the cause of the problem.

your VGA port is not working ..tight the screws of VGA cable

Are you by chance using a mainboard diagnostic card? Asus use beep codes to indicate different bios issues. I'm almost certain it is the Award Bios used on their boards.

check power supply in back to see if you have on and off switch but you would'nt be the first with this problem from dell about the power supply going out meaning:

if you don't have nothing happening when your trying to boot the computer then it's the power supply, plug in computer power up and feel in back to see if the fan is blowing if nothing power supply is gone call dell.
