Yep, possibly. In case you have DOS installed on the hard drive, you can also use GRUB4DOS [1] - just put gentleos.elf on C:\, run grub.exe, then `kernel /gentleos.elf`. You may fi…

Thanks, so glad people like the code! I keep looking for ways to make it simpler and more obvious. > - noticed krn_main() ends with `while (1);` [1]. I would've expected a "schedul…

The only AI-generated artifact is the cyberpunk wallpaper from the last photo, I'll admit that :) Btw. the QEMU screenshots are still in the repo in https://github.com/luke8086/gen…

All the photos are real, though it took me *lots* of time to get them somewhat right. The display on T1800 is indeed "challenging". What helped was: - Letting it warm for a while -…

Oh sorry, a quick google check told me PS/1 had 286. 386SX itself should be supported, the monochrome Toshiba on the photo has 386SX/20 with 10MB RAM.

Even on 2MB, you should be able to at least see GRUB, which would tell you that it can't load the kernel. Does it go blank before that? This could mean an issue with either GRUB or…

Thank you so much! Somehow I haven't heard about Uxn before, but it seems very cool and I'll definitely look into it.

In this context, 32-bit means the minimal requirement. You can absolutely run even the 16-bit version on a 64-bit PC, provided it has BIOS/legacy-boot mode. It only won't work on m…

Good catch, the yellow and blue colors are totally inspired by BeOS :D I'm even adjusting the default VGA palette to get the right tints in 16-color mode.

For PS/1 you'll need the 16-bit version from https://github.com/luke8086/gentleos . A floppy image is provided in releases. Note you only need to copy the first 64KB, the rest is j…

Hello HN, I've been working on a simple OS for tinkering and running bare metal apps on vintage PCs. Since I couldn't quite decide whether to target pure 16-bit, or slightly more c…

Bootloader developers used to be particularly fond of Forth. For example, for many years the FreeBSD's 3rd-stage loader used FICL (Forth Inspired Command Language) for scripting [1…

This was also my first thought, but looks like it's already designed to be toolkit-agnostic, like NetSurf. So it should be easy to port to fltk or anything else. $ ls -1 fixgui_\*.…

Yeah, you're right, sorry for the confusion! I've just rewritten this part to make it more clear.

On the other hand, note it only shows 133MB of total mem, rather than 160MB that is installed. I believe the missing 27MB is used by the kernel (the kernel file itself is 23MB) and…

Yeah, I suspect so! To be honest, I wouldn't notice this issue at all, if it wasn't for FreeBSD which refused to boot right off the bat. It has a more advanced bootloader though, s…

Interesting, I never noticed that 80x24 resolution. Apparently it's been inherited from VT100. Now 80x25 was the standard text mode of IBM PC, which I'm much more familiar with. I …

Actually one of the reasons for writing the app was to reduce my compulsive browsing of social media. A feature like this would go in the opposite direction :) But if you really wa…

Eh, to do it properly, 40 cols and less would require adjusting the whole layout and I just want to keep the code simple. I'm also not sure if the code would be fast enough to run …

To be precise, it only assumed 80x25 terminals with 16 colors, which I think fits into some definitions of retro, but I see your point :) I've just added support for ascii & monoch…

Sure, that's how I use it. In every message you can see its URL in the Content-Location header. You can press 'o' to select it and open in a browser, and you can select the browser…
