I guess you could use it though I heared that some hard drives never worked on any other controller card than the one they came with, though I only have one MFM hdd and I never tested it with another controller card. However I also often heared that if you want them to work with each other, you need …

Maybe install older versions of Directx next to the newer ones ? Even though it should have a good retrocompatibility, I know a few games that needs an older version of directx to be installed with the newest one they come with. So if it works for games, I guess it can also work for some obscure …

The bottom one has a late 90's/early 2000's look so I'd say the first one for a 486 and the second one for the pentium ^^

Or maybe instead of making an expansion card, just plugging something in the VGA connector that would read each pixel's color and apply it to the numeric/sharp picture. This will probably be more complicated and if your card has too dim/bright colors, this would also be applied to the numeric …

Both work at 3.3v so it should be okay. Though I don't see any jumpers to set the voltage, so I don't know how that works. What may differ between the intel and AMD is the L1 cache settings I think

Just set it to 3,4. They say that all of these settings work for the DX4 so if you want to run it as fast as it can, set it to 3x multiplier ^^

Hi folks ! As I recently received a bunch of old CPUs (in which there was an am5x86 and an am486DX4 with write-back L1 cache), I wanted to upgrade the intel 486 DX2-66 that I did put on that board. Unfortunately, while the DX2 seems to work perfectly (I don't use that computer that often at the …

Interesting is, that if I choose "Adlib" in PinballDreams 1+2 or Pinball Fantasies I always get the Digisounds, but they don't sound very nice, there is a sort of "crackeling-noise" that 's louder in PB-Fanatsies, but PD1 and 2 are "OK". Isn't the game using the OPL3 as a DAC ? I think I heared …

The speed you burn CDs also have an influence on how "compatible" the CD will be. Try to burn them at the lowest speed you drive can do. I burned an el-cheapo CD with Quake at the lowest speed it could get and I don't recall finding any computer that couldn't read it. Now I remember the CD drive of …

Had the same problem with that board and cpu. It ran perfectly fine configured as a dx4-120mhz (3x40) and even at 3x50fsb it was fine and stable! But selecting the 2x multi (=4x) gave all sorts of problems and it was very slow and unstable (or not booting at all) Finally i updated the bios (yes, …

uuuh I tried the "AP4X150" bios and the motherboard was not pleased at all ... It made low tone beeps after the flashing and did nothing else.

Sure I'm using a heatsink with a fan (if you look at the bottom right corner, you can see it's plugged to the motherboard). I've not checked for bios updates but yeah this might help, I don't know. My motherboard was made in late 1995 (the DX4 it came with even had a "Designed for windows 95 " …
