Hello, I recently pulled a motherboard out of a ARCHE RIVAL 286 case. There are no manufacturer markings to indicate who made the motherboard. The only clues are PAT-7.2A and Y-7.2 printed in a corner and in the middle of the ISA slots, respectively. Also has an ARCHE sticker on the board. CHIPS is …

46and2 etc- when the Kenitec/Arche machine boots, what is shown at the bottom of the POST screen (bios etc)? I've got an ARCHE RIVAL 286 motherboard, but I don't know the manufacturer and I am trying to get the jumper settings for the board. Any assist would be helpful. I did dump the bios chips ( …

Hello, do you know the manufacturer of the ARCHE motherboard? I've got an ARCHE RIVAL 286 motherboard and the only clues are PAT-7.2A and Y-7.2 stamped by the ISA slots. Lots of CHIPS chipsets on the board too. Thanks!

Everyone, you were right about the quality of the batteries. So I put in a brand new Energizer CR2032 3V. Computer and PSU fired up. No issue with CMOS memory or checksum. So, I've go to wonder about those Sony CR2032's with an indonesia stamp on them I got from Amazon. What I'm suggesting is I'm …

I'll test later today. I want to say the PSU won't even turn on...no PSU fan activation and consequently no motherboard firing up the video or keyboard lighting up. today I'm going to go to the store and by another sony CR2032 battery because I was reading that sometimes there are fakes being sold …

230 MA for amperage on new battery. old is well maybe .09

Appreciate the response. I have two brand new Sony CR2032 3V lithium indonesia stamped batteries. Yes, + is on the top. Multimeter says 2.83V. Old battery is .22V . Original battery is stamped Sony CR2032 3 Volts Lithium Battery A. No bulging caps that I can see anywhere/no leakage so that's good. …

Also, wanted to add a couple of other thoughts. After I had done the orange capacitor replacements (see pics above), I couldn't get the mobo to boot as we talked about. I was using ATX power supplies with an AT adapter. In a last ditch, I broke into my trusty 286 and "borrowed" the AT power supply. …

Everyone, old thread, but mystery solved. Bad keyboard controller AND Cache chips. Also had to run a trace wire on the mobo because those traces we talked about on the mobo were really corroded. Oh ya, also replaced some capacitors. Crazy. took 1.5 yrs off and on to solve. This board got a lot of …

Everyone, I could use your help solving a problem I've never seen before. I replaced the dead Sony CR2032 3V lithium coin cell battery on a ASUS PSB-S motherboard. Here's the problem. Power supply and computer won't even start with the new battery. No fan spin. No nothing. If I put back the old and …

I gave the motherboard a bath and tried to post. Still no video. Aslo, the CPU is not getting warm but the keyboard lights do light up. Will try to re cap the board.

I gave the motherboard an alcohol bath last night and am letting everything dry. Will probably go ahead and recap the orange ceramic capacitors too. When i go to boot up again, I'll put in just the CPU, minimal RAM and cache and a video card. Then I'll check and see if the CPU warms up and if I get …

closeup pic of battery damage

Everyone, really appreciate the suggestions. I'll post better pics. That battery acid damage is a pain to be sure. I'll take the suggestions and soak. The battery spillage occurred well before I owned the board. It was working fine before I moved. I will see if the CPU gets warm as suggested. Will …

pics of the board

I am posting because I need your help. I have a ISA-486V2 Rev 2.4 motherboard that is not posting and has no audio beeps. When connected to a power supply, there is no video either The details: This board was working not too long ago. I started getting keyboard errors when I moved from DC to FL. So, …
