Though Riva128 is supported by UniVBE to get those 15-bit modes. And it has superb DOS performance. And when it's not about 15-bit, it supports a great pile of crazy low res VESA modes like 400x300. The main difference between this and Voodoo3 is that its truecolor modes are 32-bit while Voodoo …

No problem, I have enough common sense not to try to play OPL music on the GUS, especially not on an XT 😁 Oh, OPL. I have a pile of .HSC music, do you plan to support these? They have a very simple structure, exactly like some uncompressed module - with OPL2 instruments.

I bit the bullet this afternoon and set up a GUS in this XT board. Well, two different ones as the ACE I tried first didn't really work as I wanted it to. After two unsuccessful tries it finally started to play music in ModMaster but it was quite garbled. When I removed the turbo jumper it started …

I'll have to try it as soon as I can muster the energy and motivation to forward it to the XT's SCSI HDD.... (And it tells you …

Probably they simply load the music files into system memory the same way, regardless of the sound card then "forward" the samples to GUS memory once the entire module is in. Or they handle GUS the same as an SB and do software mixing and only upload the output buffer(s). Just half educated guesses …

Curious, I think that not many Socket S7 motherboards allow down to 1.3v, it would be interesting to know at what voltage the processor could maintain its standard frequency. It is something like the opposite of overclock, to overclock you often have to raise the voltage because this is the …

Well I tried it with a few things and often went too low for stock speeds but I vaguely remember that a k6-2+ was so cold at 1.3V/150MHz that it could run even without a heatsink and a Palomino 1700+ was stable at 1100MHz at a similar voltage (it was actually a messed up mod for overclocking 😁)

Btw I have a Digital Celebris 560 board with (the same?) VLSI chipset and it has a strange quirk. It can only support "3 sides" of memory (pairs) - so its configured like yours, a pair of single and a pair of double ranked FPM SIMMs. It's EDO tolerant too but doesn't seem to benefit from EDO RAM.

On a side note, 3dbench is heavily video speed dominated. What do these boards give in landmark or speedsys in this categori with those cards? I suspect the P5 result will be abysmal while, if my memory serves, the EXP8449 had top notch PCI speed for a 486.
