DOS ain't dead - MSDOS 4.0

MSDOS 4.0 (Announce)

posted by usotsuki, 30.04.2024, 17:41

When I heard about this, my jaw hit the floor. It's actually ALMOST close enough to my targets to completely obviate it. (And almost all of it Just Worked®™© to roll it the first time. I had trouble with select, xmaem and xma2ems but I don't give a damn about those.) 2.11 was a long way to go but this is 4.0 - outside the kernel and shell there wasn't really that much evolution up until 6.2.

I've started to try to get it migrated off the Microsoft tools, but they did use a lot of MASM-specific stuff that WASM doesn't grok. My goal is to have an ironed-out source tree I can cross-build (no need for DOSBOX) or roll native.
