Yes, you can use software but hardware doesn't require software, ie a TSR loaded. It's just better. If you can only use software, use it. If your motherboard has a SB-Link, I'd rather use that.

6-pin connector on card and motherboard populated with 5-pins, wired straight through. Meaning that pin-1 on first connector goes to pin-1 on second connector and so forth. Most 440BX motherboards have them or the spot where they would go. Some early PCI sound cards had them or the spot where they …

SB-Link allows the card to access DMA and IRQ in hardware as if the PCI sound card has access to the ISA bus. More or less.

I am working on a new machine that will be my primary retro box and have been working on it for months as time permits. Been through many motherboards, processors, sound and video. I am narrowing in and noticed something really odd and was wondering if anyone else has experienced anything similar. …

I never saw a 300A OEM, not saying they didn't exist, just never saw one. I think mine ran up to 504 but I cannot remember voltage, probably 2.1 or so.

If anyone is interested I can get pictures of resistor locations and what they do for voltage and bus speed.

So, has anyone been gutsy enough to replace cache chips? I guess I am the guinea pig then. Looks like donor for cache is going to be a P3 500.

As far as the multiplier limiting it seems I read that a lot of the overclocking boards would report to the CPU that the bus was 66 when it was really 100. This seemed to give more available multipliers in the multiplier limited CPU's. IE, tricking them for more speed.

The box is being crippled the right amount to emulate a 486 and crippled a little more for a 386. There are quite a few games that it will need to run at full speed. That newer TimeMachine from Phil is not nearly as compatible as his older stuff. The K6-II/III+ is way more tunable. The one mentioned …

Okay I'll try to explain myself. I have found that the S3 Virge/DX, 4MB, PCI is my favorite DOS/Win9x video card. End of story right? Well, maybe not. Okay, so why do I think this is the perfect card? Everyone has their own opinion on what makes a card perfect. For instance what is the perfect car? …
