Running Boot Camp on a Mac Pro? If so, then you've probably noticed the sluggish drive performance when booted into Windows XP.
Terrabit came up with a solution that uses something called "slipstreaming" that creates a modified Windows XP install CD-ROM with the needed drivers to speed Mac Pro disk I/O from under 4 MB/s to over 60 MB/s. Fortunately, only Mac Pro models are affected by this issue.
I have a simplified version of this technique (with lots of screen shots) on my web site if you need additional details.
