I'm not the target audience for this, obviously, but I have to wonder: why aren't benchmarks made to work with the shareware version of games that have one? It avoids encouraging piracy as you implicitly do in the first post, and no one is going to (or at least no one should) buy a game just to run …

Not trying to batter Keropi with PC-DOS 2000, but can't you still overall save memory by loading command.com high? You have no umb, but given ibmdos takes only about 19k, I'm guessing you have high memory. Loading something 'high' refers to putting it in UMBs, not in the HMA. The latter is …

I don't know about that, I'd want some confirmation. The graphics card shouldn't actually care about the OS, especially since almost all the time in software rendered 3D is just copying data into video memory. The slowdown with translucency is very odd; of course similar things happen in the Doom …

That agrees with my results. I don't know what he has different; it seems 7.0 and 2000 are the same in this respect. I haven't heard of PC-DOS 7.1 having LFN support. It was never even completed, so it couldn't (because all utilities have to be recompiled to allow long filenames).

Well, I was just going on the memory usage I find (with 7.0) relative to what you showed. DOS normally is pretty much system-independent so I'm not sure why you get different results. Maybe 2000 uses more than 7.0, or there's something different with your HMA usage (without an HMA at all of course …

Yes, 7.0 gets you about 3K more even without UMBs. It is targeted to help even more with UMBs, though, by loading COMMAND and part of IBMDOS high, and reaches 629K out of 640K free, probably the highest of any DOS. Does UMBPCI even work at all on your board?

How did you achieve that underclocking? Was it by using a 2400/800 on a 400 FSB? Maximum power consumption is only linear in frequency (to first order) so I'm not surprised it would still overheat (~30W). I would be interested in getting it fanless, too, because of the noise, but I don't think it …

Without knowing what the application is, obviously there's no way to comment on its use. Perhaps you don't specify because you're afraid it would get the thread locked? (Which I suppose is not unreasonable given the history here.) As far as I know normal DOS applications, I mean the kind you are …

Yes, PC-DOS 7 was specifically optimised for maximum conventional memory available, and surely is the best of the classic DOSes for this and other reasons. It was a dead end though as IBM decided to stop competing with Microsoft in the OS field after Win95, more or less. If you're running a classic …

If this really works then it would be interesting to test on a Z68 with PCI slot and test a SB ISA card in it. No, a bridge adapter again will only provide DMA on 8xx chipsets, which support it through a bridge. On later ones you will have the same situation as with USB adapters. Same with the SB- …

Well, I should have omitted the word 'the' - I was referring to copy protection in general, not in SQ6. Are you able to write a real or virtual CD that it will run off? If you have the files from SQ Collection, and they're still in the original directory structure, it should be easy.
