OK. So I've tried some stuff and learned some things. As I mentioned before the crackling somehow goes away when I go into the DIAGNOSE utility and get to midi on page 2. Since I am unable to exit the utility in this state (I must complete the diagnostic or the sound card will crash and spew noise), …

No, with all the pulling the card in and out for testing, I didn't bother.

This is a bit tricky of a problem. The original card that I've had in this computer forever was a CT2740 and over time it stopped working. I went through a huge ordeal years ago to find out it was a heat problem (probably a failing chip) and as of today, it's pretty much dead after 30 seconds of …

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 …

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 …
