Ok, well I recently bought a toshiba satellite P105 S9337. What im trying to do is downgrade from vista to XPpro, reason behind it is that with vista installed every PC game I play have hiccups every fews secs, making my framerates from perfect to horrible. Anyways. Seeing how this laptop has SATA HDD, I needed to put the drivers in a Floppy to support it. So when i start Installing XP i press f6 to add devices, and select the devices from the floppy for xp. Problem is after doing to that the screen stays blue and after a few mins I get this message "File cpqarray.sys cause an unexpected error (12544) at line 3514 in d:\xpclient\base\boot\setup\setup.c So if anyone can help me i would appreciate it.
