Isn't the 2144-m51, 2144-131 and 2144-141 nearly identical ? I found a 2144-131 recovery disk at Archive org I have a few different versions, one is the m51 version from another user here on the forum but as soon as it tries to load from cd is gives the error 99 message. I have tried 8 different cd …

Same issue for me and no luck resolving it. I have updated my m51 bios to the latest, tried multiple boot floppy versions and cd versions.

Here's the boot disk .iso https://www.dropbox.com/s/w69s8d4d9tfeokh/ibm%20boot%20disc?dl=0 and here's the Recovery Cd .iso https://www.dropbox.com/s/s83z2l8vp8f6r4l/IBM%20Aptiva%20Recovery%20CD.iso?dl=0 I'll work on uploading the extra software as well. Check back! I have tried restoring my 100mhz …

Yesterday I managed to get my Pentium 166 MMX (black and silver chip) to 266mhz with a 75x3.5 multi and 2.9v (instead of 2.8). I used a 128mb cl2 pc133 chip (will only recognize 32mb for some reason). The board I used is a QDI P5I430vx/250DM explorer II Speedeasy motherboard rev 3.0 PCB. Updated the …

I'm having this same issue, what bios file ended up working for your board? i'm trying the ss version because i have the SMC chip described with it, but i can only hot swap flash with another board and it doesn't seem to be working. Still have a low tone issue and don;t have the original bios to get …

Used to use it as a benchmark back in my Pentium 2 days. It basically fly's around a 3d city with a matrix theme, and reports FPS as it goes. It's called "Matrix III". Voodoo files had it but it's no longer there. If anyone has it, I'd love to have a copy for old times sake. Here's the link of what …

Good point, I suppose after I post the 3.1 bios maybe someone else can check to see if there are any differences that can cause issues between it and the 1.72f bios.

I am running an HSF, one of the ones that the CPU slides into, and then turn the heatsink and it clamps onto the cpu, with a very light layer of thermal compound on the contact area. The heatsink itself remains cool to the touch at 133. I think my 256kb of 20ns cache chips may be limiting me to …

I have it up and running! though it wont boot to windows at 160mhz, hangs as soon as it tries to load the boot sector. Tried upping voltage but it wont post with anything other than stock voltage setting. have to live with 133 for now. any tricks on that front?

The jumpers are different! you may have just saved my life! Maybe somehow the jumpers effect how the cpu talks to the memory, hence my intermittent memory beeps.

Hi folks, I'm having a heck of a time getting a working PCI 486 board. I've spent well over 300 dollars now on boards that have seemingly arrived DOA. I have an ADZ 5x86 AMD cpu in the machine running at the Cyrix 5x86 voltage of 3.6v rather than 3.35 to be sure it will post. So far, this 4DPS ver …

Well first things first I need to get it working and saving bios settings. No point in anything else till then. It runs fine at the 4v setting (actually 3.7v) at 166mhz which is fine with me.

I don't know of a setting in bios that allows me to set the voltage. I still have not been able to trace the battery voltage beyond the southbridge chip where it's obscured from sight. I've been looking with a voltmeter with no luck. At one point i had voltage at the bios chip slot, but I don't have …

That's the problem, the cmos will not keep any settings, it resets the defaults every time it posts even if you keep the power on. The computer is stable at 160mhz at 4v setting. but it's useless if i can't set the bios. I'm also not sure where to measure vcc to vss.

Just for reference, the battery is at 3.10v, I have tried to trace the battery power from the battery but i'm not very good at this kind of thing. It leads to a diode labelled "d3" about half an inch from the battery, after the diode the voltage on that line is 2.81v. I have not managed to find …

Hi everyone, I have had 2 of these boards and both of them have had the same issue. The first board posted ok for a while, and then stopped out of the blue. It would not maintain CMOS settings and after each post it would claim a bad cmos checksum and revert to defaults. The 3v lithium battery in …
