I guess if it's 96% used, you definitely don't have room for a 65536 (256x256) byte LUT to avoid multiplying...

Here's a detail view of how DOSBox, for example, handles 640x350 upscaled to 1600x1200: dosbox_640x350_1600x1200_detail.png I'm not really sure what this type of scaling is called. But it seems to involve shading a little around the edges of the pixels so that they appear perfectly even to the eye …
Re: Override mount directory within a program
Posted on 2025-03-03, 23:17
In the documentation (Yes, I actually read it) it strongly advised against using "mount c c:\" for safety reasons. Yes, because it gives the DOS programs access to your entire drive. But that's exactly what you're trying to do anyway, by escaping the sandbox imposed by only being able to access …
Re: Override mount directory within a program
Posted on 2025-03-03, 22:29
I'm struggling to understand what you're actually trying to do. From your opening post, why not just use "mount c c:\" if you don't want extra path translation steps?
Re: Which New HDDs R Still Made as 512e(or 512n),thus Usable as Spare/Upgrade Parts for Legacy PCs & Legacy OSs.

A drive has to be one or the other, it can't support both sector sizes.

You can put an MBR partition table on any 512b sector disk, it just limits the partitions to being within the first 2TB. But typically what is done is one of the MBR partitions points to a GPT that has all the "proper" partitions.
Re: Boxedwine not running question
Posted on 2025-02-23, 12:20
What really puzzled me was how long the emulator just twiddled its thumbs before throwing that error. It was either being very, very slow or it was doing something it really shouldn't have been doing. Not sure how Boxedwine in particular is handling page permissions for generated code (i.e. if it's …
Re: XTMax - Software Defined 8-bit ISA expansion card using a Teensy 4.1
Posted on 2025-02-23, 07:51
The battery only keeps the RTC part of the Teensy running, not the entire thing. It's not particularly well-tuned for low current though - batteries last roughly 4 months. So an external RTC will last a lot longer.

Re: Change Cpu cycles based on game?
Posted on 2025-02-23, 03:10
You are not running the config commands from a batch file. You are passing them to DOSBox.exe as individual arguments. That is not going to work.

If the output signal mode is HDMI rather than DVI (and I can understand why it wouldn't be - HDMI is more complex for little benefit if there's no audio) you could signal the output pixels as double-width. So 960x1440 pixels (which @70Hz would use a pixel clock of ~96MHz) would end up being rendered …

That's not how you're meant to pass executable commands as parameters. You're passing one command there, "PLAY.BAT".
Re: Problems adding a CD-ROM drive to a Compaq Deskpro 386/25M
Posted on 2025-02-22, 03:05
The point is to not have the new CR2032 wasting precious current fighting the internal resistance of the old dead battery, especially when the RTC is being powered by the PC.

Posted on 2025-02-22, 02:28
Note that you do not need to grind out the negative trace, it is connected directly to ground and any GND point will do... What you should do is cut the exposed positive trace and connect the new battery to the lower half - otherwise you're trying to charge the old battery from the new one.
Re: Forcing 4:3 with VGA240

If the card was connected to the monitor digitally (using DVI or HDMI), the monitor would probably scale the active picture to fit the screen (hiding the blanking area). But it's also likely to get stretched horizontally because the digital transmission methods have a minimum dotclock speed and use …

If there's no HDD connected to the AWE32's IDE then there's no point making the XTIDE aware of it. Worst case it's going to foul things up if the AWE32 is PnP and doesn't get initialized before the ROM starts, because then its IDE won't be available...
