You actually have one of those mythical DEB upgrades in your M24? Wow.

Also colors are weird in dos programs... does cga need some modes set in config.sys in dos 5? Nothing should be necessary in config.sys. The M24 is compatible with CGA at the register-level. What exactly do you mean with weird? One limitation is that the M24 does not support the undocumented cyan/ …
Re: Looking for a VGA card that can drive an MDA monitor - what are my options?
Posted on 2025-05-15, 08:52
I have such a set-up, with an ATI VGA Wonder-16 hooked up to an IBM 5151 monitor. It allows for all EGA modes on this monochrome monitor, including the color modes, shown in greyscale. It even pulls off 16 shades of grey on that monitor, through the use of pulse-width modulation (PWM) techniques. …
Re: FastDoom. A new Doom port for DOS, optimized to be as fast as possible for 386/486 personal computers!
Posted on 2025-05-14, 22:45
Fastdoom is written is for 32bit processors, it doesn't really make sense to have 16-bit binaries compile from the same codebase. It would just be a total mess. I thought it's mainly written in C, not 32-bit specific assembly. Even if something (particularly a protected mode DOS game) is written in …

i guess i have to give up on solving this. i've been trying to engage with the developer starting back in march 2024, but i guess he's lost interest and has abandoned the project at this point. in any case, attached are my compiled usbddos and usbddosp binaries (current to commit 54345d0) for …

EDIT / Slightly OffTopic: Development has slowed down a bit lately, as I'm currently focused on other side projects, this time unrelated to retro hardware or programming. In fact, I'm now doing endurance racing in a '97 Civic 😄 Quite a change of pace, in more ways than one. :sweat_smile: Have fun, …

That was way back in 2009 or so, when Medvedev was still president (long before he went off the deep end), and when Russia was still on relatively friendly terms with the west. I have the feeling that this government funding initiative didn't really end up going anywhere. It's no secret that many …

FWIW this is my card, as you can see it's really minimal, the game port is a dummy and the passive components to make it work are not fitted. The "enhanced minimal" version : it has longer traces, it runs with Netware and is "Year 2004 ComplanI" :) https://www.olx.kz/d/obyavlenie/zvukovaya-karta …

Only the 14 and 16.257Mhz clocks are standard. You may have other crystals on a SuperEGA card, but they're not guaranteed to be there. Yes, I agree. By the way, there were also CGA video cards that worked with TVs and monitors with PAL/SECAM frequencies. That is, with a line scan frequency of 15625 …
Re: Tiny Vortex86-based DOS gaming PC - weeCee

Are you telling me I could inject the Trio32/64 Video ROM (it's dumped and can be currently used on the MAME project for the ct486 driver) onto the Vortex86 DX BIOS (using AMI MMTOOL) and it's graphics chip would work as a Trio32/64? I *believe* scroll routines are part of the VIDEO ROM. That would …

Any idea if there is a better video ROM for the VOLARI Z29S graphics chip that the Vortex86 DX has? I know the video ROM can be replaced by dumping the SOM BIOS with BIOSMP.EXE and the video ROM can be swapped using AMI MMTOOL, but I need to know if there is a video ROM better suited for DOS VGA …
Re: Linux kernal going to drop i486 support

Here is a cool blog post by the developer of i486SX_soft_FPU, a project to restore FPU emulation for 486SX CPUs on NetBSD 10.x. @Jo22 NetBSD is probably the way to go for a lot of hardware that even newer versions of the Linux kernel don't support anymore. And NetBSD does have a Linux compatibility …

If Linux becomes an OS that targets modern hardware all the time, then what's the purpose of it? 😟 Then it's nolonger useful to the hardware hacker who wants to get a 35 year old webcam going. Or likes to use Linux for testing purposes, for all sorts of hardware, no matter the age. @Jo22 There's …

Can any of you maybe try this tool on Supreme Commander? I remember reading somewhere that this game would sometimes crash on 32-bit Windows, even though it was a 32-bit game. Apparently this was because the game was quite memory-heavy for its time, and it would sometimes run into the 2GB …
Re: React OS now with Voodoo5 support
Posted on 2025-05-07, 12:37
Iirc, it was license incompatibility. It's GPLv2. Is it just because the Paragon NTFS driver sources might have the GPLv2 variant without the "or later" clause? Is that really it? I find it doubtful that ReactOS doesn't already have other sources ported from other projects that also are licensed …
Re: React OS now with Voodoo5 support

NTFS support always had been non-trivial, it's not ReactOS' fault. DOS, Linux and Mac OS X used to have read-only support for a long time. The Fuse drivers are sorta stable, but delayed writing isn't being recommended (data corruption etc). Fuse drivers for NTFS do exist since for 20 years or so. …

Had no luck getting W98 working with the SATA controller in AHCI mode (it works with the original BIOS). It does boot from the SSD with the controller in legacy mode, but I'm still unable to make any other port besides SATA #1 work. Have you tried the Windows 9x AHCI driver by the late Rudolph R. …

It is smooth and had no issues in Final Reality, but is missing half of the textures in 3Dmark 99. I havent played SGL capable games on it yet, but it came with an Evaluation CD that has about 10 …

When did they quit making vortex CPUs? (Those are just a 486) The Vortex86DX and later models support the CMPXCHG8B instruction, which is basically what makes a CPU "Pentium class". Quoting the Phoronix article : The kernel patches would remove support for CPUs lacking TSC and CX8/CMPXCHG8B …
