Hi there,
Few months ago i bought a SUNTAC 286-12 motherboard from ebay..
Here is the sheet from this motherboard:
http://stason.org/TULARC/pc/motherboards/U/UN … ml#.UavUGT6poyw
Its for 90% the same motherboard as on that sheet here above in the link..
1. The first weird thing is, that this motherboard has a AMD 286 -10mhz processor in it.. I dont think this is standard on this boards, because i think they all where 12mhz versions i guess.. I dont had any opportunity to test the max speed of this board.. But my senses saying that its running 12mhz on a 10mhz processor.. Could it be that the previous user had to replace the processor (on a budget) So he just sticked a 10mhz one in and just let it running it on 12mhz speed.
2. I have some bios problems.. I have made some pictures, so its easier to explain whats its going wrong..
The problem is, when i start this board its counting all available memory.. At the first time it gave a bios error (had solder a new coin battery socket in, because it aint had any battery installed when i bought this board..
This board have a option for a coin type.. So i thought, better then this i shouldnt find.. (coin batterys have a very low fail rate,(i never havent seen a leaked coin battery, so the choice was easy to made)
But when it arrives to the bios it saying press `del` to enter bios.. But if i dont i really dont get any sponse (keyboard is in good condition).
I look likes the computer is hanging.. After a minute it gave me a second chance to get in the bios.. with F1 and that works..
Then it asks to choose from settings or bios diagnoses..
I can enter the settings, but cant get in the bios diagnoses.. Its saying that a wrong rom type [27128, 27256].. Ill ready checked if the rom type setting was set wrong.. But i tried both, but no progress at all..
I will upload the picture now..
The best things i got with this board..
Soldered coin battery works perfect.
Had some memory left (DIP 531000 ones) because the board doesnt support any sipps, and i had still some dip laying on me desk.. So i thought i just put them in this board.. Now its having a total of 4MB with Dips installed..
Tomorrow i wil upload the rest, now its a little late and need te sleep.
~ At least it can do black and white~
