Hello everybody..
I need a help to fix my 386 system. My system is not booted up.
Nothing is happen after the powercomes in except beeping three times.
I tried to change all cards with the other but...
I guess the mother board has a problem. But I don't have the
information on the error code (beeping three times).
My system is
386 16Mhz
Motherboard is "MYLEX V2 " (1987)
BIOS AMI (11/30/87)
Hard drive ID130-AT
Ethernetcard Sytek Ethernet
and FDD, Mono video.
Does anybody give me an advice?
How much will it cost to fix?
Do you know the phone # of American Megatrends INC.?
Any advice,please......
Soonam..

Try another video card in the motherboard and see if the problem clears up. -- Roy M.

Hope this helps. I have a 20 MHz Mylex Motherboard with the same BIOS. When I attempted to upgrade my ram from the 1M standard to 4M (bank 0 filled with 1M SIMMs), I heard the same beeps. The manual says that it has sensed a problem with the '64K BASE MEMORY' prior to sensing video and thus provides the beep messages (There are 5 other beep codes). The problem and the solution were: 3 of the 4 SIMMS were faulty and once replaced worked great. Advice - make sure that the memory is sitted properly and/or test the RAM in another machine. Checking all DIPs and/or jumper settings is a given. Good luck.

Three beeps in POST ( Power On Self Test ) indicates a DRAM failure. Check to make sure your RAM chips are seated properly in their sockets. If they are all securely in place, then you must swap them out one BANK at a time until you locate the offending bank. Once you find the offending bank of DRAM, then you replace each DRAM ( or SIMM/SIPP) chip one at a time with a good DRAM chip until you locate the bad chip ( or SIMM/SIPP). If I remember right, you only get 3 beeps upon bootup if the system cannot locate at any DRAM at all. Otherwise, the POST will locate some DRAM and will only signal a CMOS checksum error that indicates that the amount of DRAM installed does not match the amount stored in the configuration RAM. Thus, three beeps usually implies that Bank 0 is failing. Try swapping the memory in Bank 0 with the memory in another bank. If this works, you will get a checksum error and the machine will boot with insufficient DRAM. This will indicate that the DRAM in bank 0 was bad. If this still does not work, then you have some other problem with the memory bus or connector/etc. Good Luck, Steve Bartling email : bartling@mozart.amd.com > >Any advice,please...... > >Soonam.. >skahng@gmuvax2.gmu.edu >skahng@gmuvax.bitnet

There is no industry standard for beep codes and port 80 codes. In fact some BIOS vendors use long and short beep codes to signify errors. This is not to say Mr. Bartling is wrong with his assessment of the problem, I just thought that everybody should know that three beeps on AMI BIOS doesn't mean the same thing as three beeps on other BIOS's. -- "Worship the Lord your God, and serve him only."

I now qualify my previous posting. For the AMI BIOS, three beeps is used to indicate a DRAM failure in bank 0. Please see my previous posting for more confusing details :-) Thanks again Robert ... it is a nice change for someone to elucidate ones posting without indulging in flames. - Steve Bartling bartling@mozart.amd.com
