Most people don't have that much. Granted, that's changing these days, but still, it's not that common or necessary or even beneficial is few OSes / apps support or need such. (Read this for some brief tidbits about CWSDPMI and the latest unofficial r6 "test".)

> SP9: re-allow fullscreen VGA

The new driver model is what is preventing this. As has been discussed before, you maybe could use old XP driver, but it disables Aero and stops some apps from running (Vista's chess game), so it's not that great a solution.

> SP12: re-allow sector access to HD via INT $21
> SP13: re-allow sector access to HD via INT $13

Most people don't want direct access available.

> SP14: re-allow exact timing

Probably due to multitasking.

> SP15: re-implement VCPI

Incompatible and not as good as DPMI. Many programs won't run under VCPI (which is just a superset of EMS, no?). Plus, it requires ring 0 access, which many people dislike (due to stability issues??).

> SP17: re-allow true RM

Impossible for multitasking and only allows 1 MB of memory anyways (unless you count the unreal mode hack??).

> SP18: re-allow unreal mode

Heh. AFAIK, only Intel, AMD, and Via/Centaur (says Lucho) support this, not some (early?) Cyrix (at least according to that dude on FASM's forum).

> SP19: re-increase XMS version from 2 to 3

It was v3 in Win98, dunno why it isn't now (XP, Vista). But as you know, less DOS compatibility, more stability. It's a tradeoff (but I dunno if that is mutually exclusive or not).

> SP20: reduce boot time from 1...30 min to < 2 seconds

Both XP and Vista boot fast, but Vista is more accessible immediately (unlike XP). And there's also ReadyBoost. But I'm not sure they recommend rebooting a lot. I think they expect us to sleep/hibernate and wake up instead. (See ACPI.)

> SP21: reduce size from cca 10 GiB to less than 1 MiB

Impossible.

> SP22: make it as incompatible with virii as DOS is

Vista's UAC is supposed to help. And virus scanners are ubiquitous (but yeah, viruses really really suck).
