Mac OSX/Win XP Blue Screen of Death
I, too, have been experiencing the blue screen within about 45 seconds of switching from OSX to Win XP. Like dj2xl, a friend suspected Broadcom/Bluetooth being the culprit. The default driver file is applebt.sys
V2.0 (dated Oct-2007). However, there is a
V2.1 driver (dated Apr-2008) at
http://www.broadcom.com/products/bluetooth_update.php.
After installing the new driver, my Win XP environment crashed again this morning!
After it rebooted, and before the blue screen appeared again, I quickly shutdown Windows [Note: Shutdown, not Restart nor revert to OSX].
After restarting in directly into Win XP, I waited for the inevitable to happen, but it didn't - no blue screen! I performed a search for the applebt.sys file to see if there were any other older versions lurking in some dark corner. The result showed four occurrences of the file; two V2.0 and two V2.1. I replaced the V2.0 files with the V2.1 file, then switched back to OSX in order to test the updated driver.
With OSX up and running, I restarted Win XP and didn't encounter any blue screen!
My faith in using my Bluetooth devices in Win XP has been restored.
