Andrew,
You do need 64-bit drivers and they do exist. The 64-bit version of XP
reportedly can't use 32-bit drivers, even through some emulation mode.
Now just like when NT first came out, you're not going to find drivers
for Joe's brand sound card and I would bet that most drivers aren't as
stable and mature as the 32-bit versions, but the big names are
supported; ATI, nVidia, probably creative labs and the bigger integrated
chipsets for sound.
For example go to ATI's driver page, windows XP professional x64 is now
listed as a selection. The workstation I bought back in November or so
is now available with Windows XP Professional x64 preinstalled so I know
everything I have is available with a 64-bit driver.
Windows XP Professional x64 is a real 64-bit system top to bottom. If
you do this in your code (pass a pointer as a 32-bit integer and then
cast it back to a pointer), it's a bad thing now. It was always a bad
thing stylewise, but it worked, now it won't work.
void myfunction (my32bitinttype x)
{
((myobject*)x)->DoSomeWork();
}
It can run 32-bit apps through the WoW (Windows on Windows) layer, much
like you could run 16-bit apps on the 32-bit windows. Funny enough, I
understand you can no longer run 16-bit apps on x64 windows which sadly
may even break some older 32-bit apps that used 16-bit installers.
