Compatibility woes / deprecation (Miscellaneous)

Yes it is (almost), for good or bad. The only reason for Itanium 2's lacking support is that it was faster in software anyways, so they decided to scrap the hardware compatibility aspect.

I know, but the OS does do some things itself, so speeding itself up doesn't hurt.

AMD does claim much improved (30%?) single thread speedups.

Can't know, just have to wait and see.

I think the README.TXT still incorrectly mentions the EMX port as if still available, but the FTP /snapshots/ shows an empty i386-emx/ dir for both v22 and v23. I'm not surprised, esp. since EMX isn't actively maintained, AFAICT.

I can't force and am not trying to, obviously. I just don't understand the rationale for dropping everything that was acceptable before.

It's just frustrating: invest all your time and energy into this ... oh wait, we've moved onto something else. Try again!

DPMI is a standard, MS was very important to its creation. It was published by a 12-member committee. Ignoring all the real-world reasons why they can't, I'm wondering, why wouldn't they want to be more compatible by running more apps?? "Yikes, 2K3 broke something, let's fix it before the next version. Oh what, we didn't fix it? Bah, we're rich, what do we care?" And yet the majority of the world is no better. All their anti-MS b.s. and yet they do the same damn thing, spit on the little guy. It's all politics instead of "hey, how do I get my app to run best?" Medicine that nobody can afford is a "big crap", not very useful to anybody.

BTW, DOSEMU claims to work (non-gfx) on NetBSD and "maybe FreeBSD", ever tried? Or would that make *BSD less appealing?

2k3 kernel = Vista pre-SP1 (NT 6.0)
2k7 kernel = Vista SP1 (NT 6.0.0001)
? = Windows 7 (NT 6.1)

Progress doesn't have to kill everything that came before it. We are not praying mantises.

Just as nobody is obliged to keep diplomatic relations with foreign countries?
