The preferred LLF utility is the one shipped with controller's BIOS - try something like "g=cc00:5" in DEBUG. Also, double check stuff like jumper settings and termination.

WD1006V-MM2 is MFM, not RLL. You can use an RLL drive with an MFM controller, but with limited capacity - 17 sectors/track, instead of 26.

I sincerely want to know who was the target audience of 2D acceleration on 16bit windows. Anybody who needed more than 640 x 480 x 16, especially on the ISA bus. High resolution and/or high color + slow bus = even the basic GUI operations like drawing windows and moving them around being painful. …

I also don't like other modern rubbish stuff, like PCI slots I don't consider Conventional PCI modern - there's no such slots in current machines. that's the thing - it is modern, and yet much of it dates back nearly 20 years and most of it was established 15 years ago in 2000 we definitely would …

I think it's because there may be neighboring tracks from an alternative format that align within the dead space where the had cannot reach. Maybe this is completely wrong, especially if the head is the same, even if the layout is different. That's how I always imagined it. If the head can't reach …

In the action genre, the first games with SVGA modes were Witchaven and Quake (1995..96), with SVGA still being optional. 1994 Transport Tycoon mandatory SVGA. I wonder if I can find something popular released even earlier. There is 1993 super-vga Harrier https://www.mobygames.com/game/18480/super- …

MEM isn't precise. Try the following code: uses dos; var r: registers; begin r.ax := $4300; intr($2f, r); if r.al = $80 then writeln('XMS installed') else writeln('No XMS'); end.

Try: mem/d/p Normally, you should see "XMSXXXX0 Installed Device=HIMEM". With DOS=NOAUTO, it shouldn't be there. Edit: also, with DOS=NOAUTO, entering "win" should fail - "HIMEM.SYS is missing."

OS/2 1.x versions were released in 1987..90, so the contemporary Windowses would be primarily 2.x (1987..89) - no protection there, right?

Nice to see that in OS/2 1.x protection mechanisms are already working - bad Windows app doesn't crash the entire system. No protection in contemporary Windows versions...

Afaik, all/most 256KB SVGA models were expandable to 512KB. It were the cheap PCB designs that caused the limitation of the time. There were SVGA chips that only supported 256 KB, eg. Acumos AVGA1 (1991), later on rebranded to CL-GD5401. On the other hand, according to the datesheet, PVGA1A (1988, …

Funnily, there's one VBE mode in 256c that can be used by low-end VGAs: 640x400 @70 Hz in 256c - VESA VBE 1.0 mode 100h The requirement for that mode is still twice the memory bandwith of standard VGA, which was not available on 80's VGA clones. This mode is targeted to early 90s Super-VGA cards …

Oh yeah, PC gaming was mostly stuck in 320x200x256 well into the SVGA era... Doom, Doom II, Heretic, Hexen (1993..95) - all 320x200x256 only.
