>No, it's an Apple Mac using an Intel prcessor (and some glue chips).

define the term "PC". PCs are just intel chips with a bios (glue 
chip, as you call it) that interfaces to whatever hardware is on the 
motherboard (an extremely wide range, excluding apple's design). if 
the apple PC isn't a PC, then neither is anything else.

>XP does not require USB to be present to install.

i didn't say it did. i said that there was a standard for hardware 
compatibility (ie bios support) which now probably includes USB. this 
is absolutely necessary when your PC doesn't have serial key/mouse 
ports.

and for those who point out that apple only supports the latest XP 
installers blah blah, it's because apple looked forwards and 
implemented the EFI stuff so that vista would work.

ok so this *really* is my last post on this issue.
