I thought XP was supposed to be NT based?

Perhaps something to do with the compatibility modes? I don't know, I'm not a programmer.

I'm really hoping Paul, or Peter will stop by and give us a real explanation for the differences.
I'm reluctant to upgrade, while so many people are having driver problems, when I just got mine sorted out.
By the way, my ATTO raid card won't work with XP, or dual processor Tiger boards. I feel like one of Peter's boy toys right now.
I bought it for forward compatibility, and it won't work with the only server quality boards I want it to work with.

For example, one of the things you could do with old drivers is when you're requesting memory, you can flag it as "Must Succeed", which means if the driver doesn't get the memory it asked for, it'll bluescreen the OS.
This makes life simple for driver writers, (as they don't have to bother with error handling) but under stress (usually low memory situations) it could cause a otherwise perfectly working OS to bomb just because a coder couldn't be arsed checking a flag.
This, clearly, wouldn't do.
So, now, if you flag a memory grab as "Must Succeed" Windows will bluescreen immediatly, therefore making the driver inoperable and forcing the driver writer to clean their code up.
There's loads of stuff like this, which basically make life worse for driver writers but much more pleasant for everyone else.
Does this help?

I noticed when I asked in ARS the guys posted notes saying what you describe, and, that with smaller heap blocks, 16k for SP, and 32 K for 2000, some of the drivers for 2k don't fit in the XP system heap block sizes now.
Also, it appears that drivers now use protected memory on startup, with XP? That's a really big deal, if true.

Really intrested to see how much of a boost 64 bit, and Itaniums produce.
