Today's catch: ATA IDE HDD 80GB and 13 x 30-pin SIMM EDO RAM. Cost me 5 EUR on a local auction site. 30p EDO... haven't seen that before. What kind of system supports it? Some very late 486 chipset with anachronistic 30p SIMM slots? Or something non-x86? Speaking of which, tomorrow I'm picking up a …

The original here was a 1287, I replaced it with a 12887. But either way, the problems occurred when the original 1287 was still in the board.

That's not RTC issue, strictly speaking. These chips also have some SRAM that serves to store the so-called CMOS settings. BIOS keeps HDD parameters in there so with the battery dead but the chip still present these settings will be there after a reset (but will fade once you power off). However …

I was half way through making a post asking for help when my final step to rule out everything possible actually worked. It was pretty farfetched though and I had exactly zero hits in Google on it, so I'll share it here for future reference. Situation: Digital Venturis 575 P75, SiS 5501 chipset, 8MB …

The P5A plays very badly with a lot of ISA cards, so even if you don't need more slots you might get into trouble with it. I kept another simple i430FX system alongside my P5A for my multi-sound-card build for that reason - but I'm replacing that with an So4 build once I fix a few things on the …

Which revision P5A do you have? 1.05 or earlier has the older D/E revision of the Aladdin V chipset which can only cache 128MB of RAM. With 256MB you'd be outside your cacheable area and would have lower RAM performance. In that case, try dropping to 64MB if possible - it will probably run better, …

Arrived today. A special motherboard, at least that seems so to me. On it a Cyrix MII 300 CPU. Special to me because I have never seen a socket 370 motherboard with EDO ram. Nice with ISA slots. Maybe this will be the base of my new favorite DOS/Win98 system (: You still haven't. This is a GVC- …

Manuals only show what was available when they came out. If a motherboard has three jumpers for multiplier (as any motherboard must with settings for 266MHz/400MHz or higher), it can be set to 5x and 5.5x - and in the case of K6-2 also 6x: One jumper: 1.5x = 3.5x 2x = 6x Two jumpers add: 2.5x 3x …

Yep, should work. I ran a K6-2 550 on this board back in the day. As for frying, voltage is the thing to watch. If you try to run too fast with stock voltage and decent cooling, it won't fry the chip, it will just be unstable or not boot. By increasing voltage you can increase clock speeds, but you …

And if you particularly want GLide, the Voodoo Banshee is generally the cheapest 3DFx option and not that much slower than a V3.

Hello i think that you can rethink again about that. In my opinion Super Socket 7 boards dont have enough compatibility with ISA 8 Bit ancient video cards.

Tbh though, most of the more interesting So7 boards had non-Intel chipsets. At the time, the i430FX was spectacular, single-handedly making the Pentium faster than 486 at last, with i430VX pushing the envelope a bit further and the expensive i430HX offering unheard of RAM support. Then the i430TX …

So that explains the non functioning slot on the FX 3000D, eh? This is a pretty interesting post. I knew about some of these proprietary local buses, but the ones from Joindata and ECS are new to me. The ECS slot is particularly troublesome, since you'd have no damn way of knowing if you have one …

A Radeon 7000 "too slow" with a K6-2 400??? Sounds more like you are bottlenecking on CPU... If you're convinced it isn't the CPU and want to try a faster GPU, I'd stick to the same drivers you are using now - you could look for a Radeon SDR/DDR or a Radeon 7500. Theoretically a R8500 might also …

How did he know for sure it was a DS12887? Generally DS128(8)7 modules tend to be interchangeable, but DS1387 (Realtime RAMified, i.e. RTC with 4k SRAM) are a different kind of beast. Boards with DS1387 don't boot without DS1387 in there and don't even begin to post with a DS128(8)7 in the socket. …

Doesn't look like an Intel adapter, they were generally full-height ISA cards. This looks like a generic NE2000 clone, maybe a RTL8019.
