Re: Best DOS video card?

Thanks for the Alien Trilogy info, I have not tested yet. May "VESAFIX" or "6bitDAC" tools can help on VBE 2.0 and later cards. I will test Alien Trilogy later. No probs. I do recall trying the "Vesafix" and "6bitDAC" on some of the cards that faied, but these tests didn't make any difference. …

ISA video cards also slow things down. However they don't slow down the CPU and can still cause issues with some games, so use these results with caution. Yep, did consider testing an ISA VGA card, but I don't have one at hand to test. I still have a S7 board for backup anyway. Your results match …

3Dbench tests for my P2, as requested, using the appropriate v1.0 and v1.0c versions: ---P2@400MHz downclocked to 133MHz, with L1 and L2 enabled--- Using S3 GX2 4MB AGP: - W/ fastvid = 174.6 - W/O fastvid = 113.5 Using Rendition v2200 8MB AGP: - W/ fastvid = 51.4 - W/O fastvid = 33 ---P2@400MHz …

Great, looks like the ISA clone cards are working well now. Thanks for testing these, they will make a good addition to the compatibility list.Couple of questions: - Do any of these cards support IRQ 2/9? No probs. I wasn't paying attention, but are you asking whether there was a "2", "9" or a …

I'll explain. From a BIOS perspective L1 is CPU cache, L2 is mainboard cache. I don't recommend Slot 1 machines because once you turn off L1 cache the machine is super slow. On Socket 7 you can leave L2 on and get a 486DX to 486DX2 depending on what CPU you have. Turn L2 off as well and you have a …

What board do you have that comes with mainboard cache? Well, my BX mobos don't have mainboard cache, but my Socket 7, Abit AX5 does (512K, IIRC). I'm not sure why mainboard cache would benefit my setup? BTW, I just tried Test Drive 3, and that works on my fast BX mobo too, with L1/ L2 caches …

Because it is lacking mainboard cache, Slot 1 machines are either very fast or super slow. So you have this huge performance gap that you can't reach. Check out my video here: http://youtu.be/gzxnB2CD6aw?t=21m33s I put the start showing what performance levels you can hit with various CPUs. On your …

Slot 1 systems come to a crawl when L1 cache is turned off. It doesn't surprise me that music slows down. Not a fault of SoftMPU. Go with a socket 7 build instead :) The music's fine (MIDI). The graphics, and sound effects, slow down accordingly with caches disabled. However, everything's fine with …

Hopefully 1.2 fixed the problems j^aws was seeing with the SB16 clones. Paging j^aws :-) Okay, a couple more tests with the newer SoftMPU v1.2, same setup: Mobo: 440BX (with S3 GX2 and sound card only installed) CPU: Unlocked P2@400MHz OS: Win98SE Synth: Roland CM-64 SoftMPU: v1.2; SB220, IRQ5, …

Yep, that's strange. I think we can rule out a CPU speed or sound card issue. Just to check, are you running under pure DOS, not a Win98 dos box? Yep, running from pure DOS. Just tested a couple more cards: SB16 (CT1750) and OPTI x924 (Crystal 4231) - identical tests as above and identical results. …

Started retesting, and got some initial results: Mobo: 440BX (with S3 GX2 and sound card only installed) CPU: Unlocked P2@400MHz OS: Win98SE Synth: Roland CM-64 SoftMPU: v1.0; SB220, IRQ5, MPU330 -----Sound card: AWE32 (CT3900)----- - P2@133MHz, L1/L2 cache enabled: SoftMPU fails to initialise - …

That PC is way too fast :) MT-32 was around when people had 286/386 PCs. Maybe so, but I've tried a CM-64 connected to a Voyetra 24s, on much faster PCs...! 1) Aztech 2316A chipset (Crystal 4248) with OPL3 - lockup after recognising ports. 2) Opti x924 chipset (Crystal 4231) with OPL3 clone - …
