Don't intend to hijack the thread, but it is somehow related. I started designing a NexGen Nx586 badge. I wonder if anyone has any image or marketing materials that could be used as a reference how the original badge looked like (if there was such a thing).

The type of socket is not important unless you want to use stock MMX chip. It all depends on the motherboard (see above) if supporting the multiplier, FSB setting and especially if can supply enough power. If you want to push limits, overdrive CPUs are usually easier to work with, I am running this …

2-port ISA ethernet card. That's unique, from my standpoint anyway. I assume you are just going to use one of the ports? Yes. The first port is 10Base-T, the second port is 100Base-VG. They cannot be used simultaneously it is one or the other (100VG doesn't use Ethernet signalling). I plan to use …

Spea V7-Mercury P64V, S3 968 2MB VRAM PCI In DOS the VRAM is approx. 2% slower (DOOM, Quake, 3DBench, PCPlayer average) In Windows the VRAM is approx. 24% faster ( …

I think vast majority of Socket 5 motherboards should run POD200 (unless they have inadequate power supply or something). It was designed to update old P54C CPUs. I've ran mine in very early pentium motherboards. Still the HX + Socket 5 combination is somewhat rare as the chipset is from 1996 when …

Which begs the questions, what defines a socket 5 motherboard? Well, the former is 320pin the latter is 321pin and that's what defines the socket 5 vs socket 7. What makes things complicated is that some vendors mounted 321-pin Sockets 7 on boards with no split-voltage support (or with support …

For some time, VRAM was used mostly for accelerated cards, while dumb framebuffers used DRAM. So, perhaps this is the origin of the (mis)conception that in DOS, DRAM is better than VRAM? That would explain it for early dumb DRAM vs accelerated VRAM cards. But more modern chips (1993-1995 period, …

VRAM is better in Windows, but DRAM is cheaper and often works better in DOS. That's what 90's magazines kept repeating. It also matches my observations when comparing equivalent VRAM cards with DRAM. But I am trying to figure out why is it that? Why don't VRAM cards excel in DOS too? I get that the …

What advice would you give to some looking to build an EISA card based computer ? I know most cards are hard to find and expensive. What cards work vanilla with Win95b/Win98se ? Is it hard to get to work in DOS ? In general the main problem is that all cards need to be configured before they can be …
