I'm sure it'll be like Win2K and XP, some are written by Microsoft, like Standard VGA, IDE, mouse and stuff, but most will be written by the vendors. I don't see the big deal with this. Vendors didn't seem to have a problem writing drivers for Windows 95 when it came out, as apposed to the 16 bit drivers they had for Windows 3.1. So it shouldn't be a big deal going from 32 to 64 bits.
And another thing, XP 64 will almost certainly be XP Server, not Pro or Home (especially not home).<P ID="edit"><FONT SIZE=-1><EM>Edited by lucol on 10/02/01 03:34 PM.</EM></FONT></P>
