Re: 486 SMP strange motherboard
I used to have one that had 4 on a single board. it was an IBM iirc, which was proprietary. that one looks like a standard AT form factor, yes it's a unique one.<--- Badcaps.net Founder

Re: 486 SMP strange motherboard
I got an ASUS board which is also AT but has a daughter card that allows for either two Pentium Pro (pfft, they could do SMP in their sleep) or two Pentium (wait, the Socket 7 ones? YES!) processors.
Going way back to the 486 era, all there really was that could to SMP was OS/2, x86 Unix, or crap from Novell.Find Nedry!

NT 3.x and NT4 could, and when it came out, most were still on their 486's.<--- Badcaps.net Founder

Re: 486 SMP strange motherboard
Didn't NT 4 come out late in the 486 lifespan?
That board does not even have PCI slot.Find Nedry!

Re: 486 SMP strange motherboard
I once worked on an old Compaq server that had three Cyrix 386 CPU's.
I dunno much about it. It just needed a PSU.

Re: 486 SMP strange motherboard
NT3.5 came out in 94, NT4 came out in 96. 486's were still commonplace then. You could still buy new 486 boards, FP RAM, and CPU's (mainly for the dx4 100MHz platform) up through about 97, then the socket 7 pentium and K5's really started taking hold and the beloved 486 began to rapidly disappear. NT3.x & 4 was designed on 486's. I never used 3.x, but I did run NT4 when it first came out. It was my first dual system, a dual Pentium classic 233MMX on a Tyan Tomcat AT motherboard with 128mb of EDO ram in it, all SCSI of course. It was a kick ass machine for the time. Soon after, I upgraded to an Abit BP6 running dual 300A @ 450/100. NT4 LOVED that thing! Then came the VP6 and dual coppermines with windows 2000.......ok, I'll quit with my stroll down memory lane!<--- Badcaps.net Founder

Re: 486 SMP strange motherboard
If they were going to go to the trouble to do SMP, why did they use the SX without the coprocessor and not the DX.Comment

Re: 486 SMP strange motherboard
Dual CPU doesn't necessarily mean SMP, some old stuff used ASMP.
Some were built to run some specific one-off OS that was proprietary to the board and vice versa.Mann-Made Global Warming.

Re: 486 SMP strange motherboard
I remember Cyrix I was turned off them early on I had a 300 mhz CPU of theirs tried to play mp3s on it with Winamp (the first time I even attempted it actually it was the mid 90s I think so they were the new thing) and the CPU power shot up and they played like a tape recorder with a gummed up capstan (sluggishly). This was a fresh install OS out of the box PC. Never bought a Cyrix again.
The Intel at 200 Mhz with the same memory and mobo hardware could play the same mp3s without a fuss. I think this early experience biased me towards Intel.Last edited by Krankshaft; 09-26-2010, 10:01 AM.Elements of the past and the future combining to make something not quite as good as either.Comment

Hello,
I have a Asus ROG Strix Scar 15 (G533QM) that had a dead motherboard (Graphics card dead) and after trying to fix the motherboard with no success, I bit the bullet on a sale for a new motherboard. I ordered a motherboard for the 15 inch model which is the one that I have, and when the motherboard arrived it wasn't for a little while that I saw it was from the 17 inch model.
My question is, can I update the Bios on this G733 motherboard to a G533 Bios.
The reason for wanting to do this is that the keyboard isn't working as it should, and I think this... -
Hi everyone 😀,
I'm here today to ask for help with repairing the motherboard of a Lenovo Legion Y540 17IRH.
To give you some context, I'm passionate about computer repair so much so that I've invested in a lot of tools and started practicing on dead and old hardware. I've been learning how to solder and desolder components, mostly focusing on phone repairs.
Recently, I bought a broken Lenovo Legion Y540 17IRH for just €150, and there are two main reasons why I made this purchase:- I already own the exact same model, but its plastic chassis is badly damaged.

Subject is a blank screen issue in HP Envy 17-3290NR 3D version laptop with motherboard Louis V1.1 6050A2489901 MB-A02. Production year is 2012. This one is a 2nd hand motherboard which I could use it for few months only. Suddenly no output from the internal display and also no signal from HDMI port then Windows out of order after few boots.
Caps lock working normally and no HP's caps-lock warning blinks. Making a hard reset and replacing the RAM sticks or using different slots didn't help.
Fans are spinning. Blindly could install windows11 and got the device manager... -
Here’s another motherboard that needed a full recap: an ASUS P5GC-MX.
This one was gifted to me some years ago by user Pentium 4, along with a few other goodies. It actually came in working order with no bulging or leaking caps. However, I noted there were United Chemicon KZG caps everywhere on the motherboard. The CPU VRM output (CPU V_core) was the only exception: it had only 2x KZG. The rest was 6x UCC TMV 4V 680 uF caps… which aren’t any good news either.
So here is what the motherboard looked like with its original caps:

Hi, I have some 32 bits computer motherboards that need repair, as they fail to
power on.
Here are some examples :

I replaced capacitors with aluminum-polymer.
