Yaaay! It worked 😀 Thank you vstrakh! The bugs creeped in because I was experimenting with different notations — the vasm's "std" syntax is different from the MOT one I used for other projects and had a hard time switching. All is starting to make sense now. Thank you again for helping!

Yeah, looking at this now it seems this is not the expected DOS exe or com format. I'm still feeling like I'm missing something obvious, as I find it hard to believe that I was able to assemble code with vasm for all kinds architectures including Amigas, Z80, several flavors of Apple, etc. but …

Thank you. This would make sense as the "message" I'm getting displayed seems to be a random string of chars picked from a different segment of memory... If that's the case, do you happen to know how to link for .com? vlink help doesn't seem to mention this.

Probably a long shot but maybe someone here knows. I'm trying to cross-compile assembly code from a modern machine, using http://sun.hasenbraten.de/vasm/ compiler and http://sun.hasenbraten.de/vlink/ linker, to 8088 XT. I am able to compile basic code (to display a string) on MS-DOS using MASM, but …

I don't have one around. Maybe I'll grab one next week but it doesn't seem this would help; to me it looks like the floppy controller doesn't even try to communicate with Gotek... (normally you would see an attempt at reading a sector on the Gotek display, but I don't see that happening).

Ok so you are using Sergey's Floppy controller, but you cannot get into it's BIOS thru F2, correct ? What address is the floppy BIOS set at (sw2/3 thru 2/7) ? C8000 would be where I would start. Yes, Sergey's Floppy controller, and yes, I can get to the controller's BIOS by pressing F2. The floppy …

Hmm never heard of ARC Turbo BIOS , do you have a link so I can read about it ? What floppy controller are you using ? The floppy controller is ISA Floppy and Serial controller version 1.0 by Sergey Kiselev. I know nothing about the BIOS and don't have links... here are 2 photos of when it boots if …

Hey all, I just bought Maya 44 PCI sound card compulsively for EUR30 and before the package arrives, I've started to wonder: how good is it for retro machines? I can see the manufacturer has provided drivers for anything Windows 2000+ (not 98 though). Is there a way to make it work under DOS? Any …

Looks quite close to this one maybe? Some chip positioning is off, but I think that's the closest at stason.org... https://stason.org/TULARC/pc/motherboards/S/S … B-SYM-486C.html

Nice. Looks like a perfect build from the Windows 98 epoch — well done. Most of my machines are DOS only, but I need to build myself one with similar specs to have a Win 98 machine handy.

85-early 90s when Amiga competed with PCs, and Demoscene flourished. Then late 90s when Richard Stallman traveled the world, homebrew devs were reverse engineering Windows drivers to support hardware in Linux, and there was real hope for Linux to win the Desktop. Excitement was in the air. Ever …

AWE64 does support OPL3, but it is not via the original Yamaha's OPL chip, but via CQM chip. People say it sounds different. On AWE32 from what I know it is mixed, some have the original Yamaha chip, some CQM.

I loved the HD sound too, it felt at home... until I started researching DOS-era sound cards when I needed undisturbed silence. That's when I switched to Flash. With almost no fan sound (Pentium 90 doesn't need one, and the PSU ones tend to be very quiet), I am starting to understand the different …
