Thanks, there are a lot of good suggestions, I'll try things this evening.

I recently got a very old motherboard with 386SX and a BIOS called NEAT. I haven't seen this BIOS before. The problem is that when I try to setup a HD, there are only specific TYPES from 1 to 45 with specific Cylinders/Heads/Sectors/etc.. I am used to other BIOSes (like AMI BIOS for example) where …

Here, jlS4DzIQ.jpeg but you are right, these modules might not work with the motherboard (I was confused and thought something about BIOS because of the conflicting message, even though I know BIOS is in the ROM and not the RAM,. but the real problem and the message should be invalid memory modules …

I think that could be. I hear of EDO, FPM, etc.. but all I know is that they are RAM that fits so it should be true. Are typical 486 memories EDO? They are SIMM with the same pins exactly, that's all I know. So, all I need to do is buy some SIMM with similar pins but they should be FPM. Also,. does …

Some time ago I bought a motherboard (called Tomato Board ) with an AMD 486 (AM5x86-P75) at 133mhz. Besides some strange initial problems (first boots it was running extremely slow and Norton SI would say something like 15 instead of the expected 288, but this somehow dissappeared after putting back …

Just a little thing I remembered. Doom required a good videocard with good bandwidth between system memory and video memory. In the past, while I was trying some weird experiments to plugin a very old ISA gfx card in a very fast CPU (Pentium 3 class) and running various software, I realized that …

I think there is a bug with my version of Mortal Kombat in my 386. Maybe it's your problem too? For example, things crawl soo much, but so much I can't even get in the menu without waiting for two minutes for the logo to fade. But it's so slow it's obvious there is some serious stall here, some kind …

I remember back in 1996 I had a 386 and was running 3D Studio V4.0. It wasn't very fast but I was patient. I had rendered a little UFO and was also rendering some models from various 45 degree angles to use as sprite graphics in Doom (enemies needed a lot of different graphics 45 angles revolving). …

Wow, we have very similar 386 machine. Possibly the same motherboard too. I have AMD 386DX 40Mhz, Tseng Labs ET4000, 8MB Ram, difference is I have no 387 coproc and only 128kb cache. Also I have installed a Gravis Ultrasound, can't remember if it's classic or PNP or other though now. My norton SI …
