hello guyz, i necro this post up because i have a few questions on the rage2c cards: 1. has anyone tried getting rage2c run on 486 systems? 2. i can't remember whether rage2c driver had official opengl support(not third party wrapper)? i also have my opinions on them: rage pro is a decent but …

since some people are already talking about cga, why not give the undocumented 160*100*16color mode a try?

If you spell the vendor correctly (that child if fair, not a fairy ;) ) you find the datasheet: http://electronix.org.ru/datasheet/FairChild/RC5053.PDF 5-Bit Digitally Programmable 1.8V to 3.5V Fixed Output Voltage • Provides All Features Required by the Intel Pentium II Processor VRM 8.2 DC/DC …

I am just coming around to thinking about that, got a Diamond Stealth II kicking around and reading about RV unloads the CPU as well as having reasonably lightweight drivers, thinking it might be a better match for my Cyrix 5x86 than other cards. But gotta get my 486 PCI boards dug out and fixed up …

To disable the MMX check at the start of 3DMark 2000, you need to patch 3DMark2000.exe . The byte at offset 69626 (hex) is originally 75 (hex) (in the context at that point, this byte instructs the processor to jump if MMX is present) to EB (hex) (which instructs the processor to jump …

yeah i consider the 440bx to be the best chipset for slot1. although it doesn't official support for 133fsb, slot1 pentium3s @ 133fsb are not that common, so this requirement is unnecessary for me. one can also try finding the abit sh6, which has 815e chipset. it is slightly slower than the 440bx …

It would be better if you defined best. Best means different things to different people. So It's hard to entertain, since everyone has an opinion about it. One way to define best is features. So you mentioned scsi and dual lan, as well as dual socket. These would of been premium features in their …

the 440bx is a cult chipset, and there were too many excellent boards made with it. since they may be designed for different purposes, making it difficult to compare, i would divide the candidates into 4 groups so you can pick one for each group: *single slot1 *dual slot1 *single s370 *dual s370 the …

how can i identify whether an early slot1/s370 board works with coppermine cpus? I presume you mean without having to look up a manual? For slot 1 it's like Oetker explained. For s370 an adapter (or other handywork) may be needed because of different pinouts. i have looked up some manuals and i …

i think its mostly a question of voltage, if it can recognize the voltage(1.65/1.7/1.75v) of coppermine then it should work. is it possible to identify by the vrm component?

For VGA cards the only way to do 160x100@256 is by reducing the rendering resolution and doubling drawn vertical pixels in software because the minimum resolution is 320x200 on 256 colors with VGA hardware (unless there is some trick I don't know). i think thats what i intended to mean. There is …
