The Trio3D is one of the last ViRGE derivates, just labeled Trio instead of ViRGE because the bad reputation of the ViRGE name aka "graphics deceleractor". The most common version is the "Trio3D/2x" which is indeed a AGP card. But most important, the 2D Core based on the TrioV2/DX still remains and …

Works in a GA-486AM/S (ELSA Erazor II - RivaTNT , 16MB). Tested in DOS only (3dBench, PCPbench) though.

Its Abit AB-PB4 and Gigabyte GA-5486AL equivalents are quite good performers and also provide a dedicated PCI 1/2 divider jumper. The performance is absolute comparable to the fast SiS and UMC chipsets. They support EDO which makes them easy upgradeable. But both (all?) are lagging a PS/2 mouse port …

Hey, that's a great hint, thx! I'll try that on my PC-Chips M571 mobo which came which a 333GP (75MHz Version but running @83MHz). And don't worry, I'll check the TNT in a UMC board. Is the GA486AM/S ok? I take this for testing because the HOT433 always is a bit of.. umm.. unrealiable you know it …

I sometimes think SpeedSys shows crap here and there.. On some machines the CPU MHz is displayed wrong (eg. Cyrix DLC systems), on other machines the memory bandwidth (not the troughput) is displayed wrong, on other machines the VESA Speed is just ridiculous low and/or the memory amount is displayed …

Referring to the SpeedSys readout the board is PCI 2.1 compliant but I doubt it supports the enhanced bandwidth (33MHz *2). I can tell you that the TNT works without flaws (ELSA Erazor II: http://www.amoretro.de/2012/03/elsa-erazor-ii-p16-nvidia-riva-tnt-16mb-pci.html ) The Geforce 2MX (ELSA Gladiac …

Yes, it's a shame the quiet CT1600 and the even a tad more smoother CT2600 don't have midi-headers. Of course you can use 2 SB16 cards, one for FX and one for the music but that's for die hard SB16 fans only. But I have an easier workaround: Just avoid a card with this bug! :lol: In many cases the …

IMO a V3 in a 486 is more or less just a demonstration of feasibility. Almost all games that take advantage of the V3s' capabilities run so much better on Pentium or faster. Of course it's cool that it works with the SiS496/497 chipset and of course the great POD has a better FPU for the more …

The biggest plus about the SB16 is that basically it will produce fairly decent sound and music for every game, be it ancient games or brand new ones and many will be in Stereo. Well that is true but for many people FM music is no "decent music" if a game supports General Midi and you just cannot …

Firstly FM music is fine so the issue only applies to Stereo digital effects. This is only true for the early models of the SB16 with a real OPL3 chip. But when higher integration processes begun (with the CT1747 OPL+DAC+Buslogic integration) the sound started to change. I think even the CT1747 FM …

Well I actually never ever flashed a BIOS in the Zida itself. This is because many 486 chipsets / boards require special revisions of the flash programs to work and that makes things unnessesarily difficult. I love uniflash and flash all the BIOSes in a hotflash-device (it' a K6plus ready SiS based …

Well I own about 70+ soundcards or so. The CT1740 is indeed a "noisy" card and has this "feature" in common with the CT1750. But if you wanna use the card you can benefit from the 4.05 DSP chip which is not prone to the infamous "hanging notes bug". But for me personally, there are better cards than …

I had set a wrong parameter in the chipset features: LBD# Sample Point should be 2 not 3. That makes ne PCPbench score climb from 8.9 to 9.5. Memory speed is not affected. It just increases the PCI bandwidth. This option is always "2" with an older BIOS (and not shown in the menu IIRC). Well the SiS …

I'm happy my hint has helped you! Maybe you gonna start to like the Tomatoboard a bit more right now, hmm ? :wink: The TO has already 2-3 short on J1. His (bad) performance is most likely due to BIOS mismanagement and/or 70ns modules. One strange thing is still the shown Vesa Speed, because with 4. …

I will post the screens later, no worries. My L2 is 62.2 MB/s and Memory 42.9 MB/s both according to CacheChk v40 I think this is on par for the chipset but can be upped a bit with a 1.71 or 1.72 version. 2x66 is impossible with the Tomatoboard, even 50MHz is hardwire-disabled (JP18) but the chipset …

@badmofo: The board you are linking is actually not a Zida 4DPS board. It is called "PCI400-4" and has a slightly different hardware layout and the PCB is not made by Zidas manufacturer TMF. Maybe the Zida BIOSes run with this board, maybe not. And with "run" I really mean "run". If you flash a …
