Yeah that's why I figured that Q2 was ram limited but also included Q1 because there's no way in hell that would use the rest of the first 32mb. Windows uses some but I had nothing running at the time. Just a fresh boot and no bloatware in the tray. It's highly likely that windows and quake operated …

Testing completed. Results are not what I thought they would be: 430VX, 133MHz, 256kb onboard L2, ATI Mach64 GT 2B 2MB 32MB RAM: DOS ONLY: CACHECHK: L1 cache = 183.7 mb/s, L2 cache = 117.6 mb/s, memory = 77.0 mb/s SPEEDSYS: L1 cache = 253.90 mb/s, L2 cache = 106.84 mb/s, memory = 75.23 mb/s, …

BTW, I am just about to remove 1 of the memory modules to test the whole "256 can only address 32mb of ram" theory. Is there a Win95 utility anybody knows of which would prove as to whether or not reducing memory to 32 mb forces the remaining 32 to be used in write-back mode? Essentially is there a …

As it happens I have 64 mb exactly installed. Maybe I should remove a dimm.

Wait... You're saying I have 256kb L2 already??? Benchmarks show negligible improvement from 256 to 512 so what's the point of the slot then?

Indeed there is no tag chip.. I see what you mean. All the ones I've seen for sale so far have one or look completely different. Just my luck these manufacturers had to be "unique".

Whoa! I'm simultaneously impressed with your level of research in being able to zero in on the correct item I need and also dismayed at how the heck I'm supposed to find it. FYI, I checked my board and it has a um61256ak chip right next to the jumpers, which appears to be a tag module? Also what's …

Older version? Hmm.. I thought newer doom releases such as "the ultimate doom" had setup files with way more selection in them. For example, I believe the ultimate doom supports sound blaster pro, which as you'll recall, worked for Jazz Jackrabbit. However if the idea behind an older version is to …

Ok so I've had a chance to do some testing and here's what I've found: Generally speaking as long as I run TBSDOS in any mode and nothing else, most games will play with music if SB is chosen but no sound FX under SB. Some games will work if they allow ADLIB sound such as Wolf3D or Jill of the …

Awesome. I will give it a shot and get back to you. If I'm successful I will re-iterate the procedure that worked. I already have a base floppy that I can use this with so bear with me while I hack away.

I suppose if the laptop is equipped with only a piezo then it would be kind of a waste for the sound card to work through that. However I have used many laptops with PCMCIA slots, which had nice multimedia speakers built in under the casing and like a previous poster mentioned, it sounds on par with …

Thanks that's awesome! The PC has this board (https://www.asrock.com/mb/via/k7vm3/) so a VIA chipset and a Barton Core 2600+ AMD processor. Can I assume from the sparsity of the files in the download that I merely need to boot to DOS and then run the exe file with the correct switches? Or is it best …

From my POV, the most ideal product would: Be completely self-contained so that there is no need for cables and the whole thing fits flush in the slot Support built-in wavetable, even if it's fairly basic OPL2 compatible or better Support PCM decompression (like the ESS AudioDrive card did for Duke …

I'm having similar problems with DOS support using this card. In my case checking the box to add dos support from the control panel causes the entire computer to hard lock and reboot so it could be an IRQ issue or w/e but I always have problems working on things like this through windows so I'd like …

That is awesome. This must be some sort of museum piece they only made a handful of because I can't find any trace of this product beyond the aforementioned. This is the sort of thing that would make you stand out at a retro computer convention if you had one.

That DOES seem like what I was talking about. Wow. I'll have to see if I can hunt one down. So I guess any benefit from either chip has to be due to specific instructions being called by the software? Otherwise it does nothing?

There is apparently a daughterboard that permits an ordinary FPU socket to accommodate BOTH an x87 coprocessor AND a Weitek processor, so that you can have super fast single precision math and your trig functions, etc. As I understand it, computers were able to use both simultaneously with no …

Nevertheless I suspect there's a reason why no other piece of software other than OCP has managed to play an mp3 on a 386 so they must be onto something.
