how do i make my pc boot from IDE and not from SATA hdd

[stracing]

this morning i tired to start my computer up, it will go through the win xp loading screen. normally it will switch to the login screen, but this time the screen goes black. last night everything was running fine. i tried boot in safe mode, still nothing. it freezes after trying to load 'giveio.sys'. now i am clueless as to what to do next. i doubt i will get much help without someone taking a physical look at it, but i'm just hoping someone knows.

now to the topic. as the subject says, how do i boot from IDE instead of my SATA hard disk? i've tried my BIOS settings but no matter what, it always chooses the SATA hd. I want to get my stuff off just incase its causing the problem described above. and then completely format my drive etc.
