Hmm.. It could work with a pre 586 computer. It must have a real ISA-Bus (without PCI-ISA bridge). I think the CPU on the mainboard must be removed, too.

I thought the DX4 is no true 80486 anymore. Some games might crash. Also keep in mind that the i486DX2 66 supports both 5V and 3,3V.

Well, DOSBox is designed for games. Not for critical applications. However, there seams to to be a dummy output for SDL available. You may ask at the SDL forums.

Well,to be honest, I didn't expect much support, never got much support when I suggested a front-end in threads either. I sometime have felt like a traitor for even suggesting a front-end! There are lots of nice front-ends. The DOSBox website even mentions some of them. The main 'problem' is that …

Currently, based on my experience, for every gamer who gets his head around the DOSBox DOS commands another three give up. If we don't change that, we are going to be the reason for retro PC gaming decline. Maybe. But that's the nature of DOS and its games. DOSBox tries to recreate an similar …

Hey, if you really want to play these games correctly, then you have to use an environement they were made for (either real or emulated). This includes both the operating system and the hardware from that era . I tested UMBPCI, and now I'm certain I have no TSRs incompatible with it. At least, …

It could help, just try it. Some webpages state, the setting defines how long (>cycles<) the currently active PCI device is allowed to use the bus before another one takes over. Note, a to high value like 255, also slows down the PCI-ISA bridge. The 64 seams to be alright most of the time. So yes, …

Test #1: PCI 2.1 = Enabled, PCI Latency = 32. These are the default settings. Incredibly, the graphics card produced a BIOS POST message. Unfortunately, it quickly went "mad", because the characters on screen became corrupted and garbled. Hmm.. I recommend PCI 2.1=Enabled, PCI Latency = 64 / 96 / …

Well, I have some last idea that may help.. Some Socket7 mainboards let you choose the PCI revision (2.0 / 2.1) in the BIOS. Alter that setting. I could help, if the card ist still working. If the card is damaged, then there's something that makes me wonder: Why does your board even startup with a …

Yes, that's right. It's from 2004 (last firmware release, Socket 939). :sweatdrop: As I mentioned, the problem occured only on my more modern boards: Two newer Trios (dated '96,'97 with VBE2.0) worked, the other four didn't until I altered that value. My old socket 3 mainboard (ALI chipset, '94) …

I'm curious what's the cause for this behavior. On my socket 3 board (80486DX2@66 with slow PCI bus) all my Trios work. Difficulties only occured on my more modern mainboards in connection with the older Trios (VGABIOS dated before 1996). Playing with the earlier mentioned setting always solved it. …

Hello retro and everyone here at vogons. I just registered to post on this topic. Recently I had some similar issues with a handful of S3 Trio64 cards.. The mainboard booted up fine (no beeps), but the screen remained black. I solved the problem by entering the BIOS and setting the "PCI Latency …
