Okay, I got a honest question...:)

Please correct me if I am wrong...

Is this Windows XP SP1 bootdisk is for those peeps don't have bootable Windows XP CDs? :huh:
Or else, the they have got bootable CDs but the BIOS doesn't support booting from CDs...but then that kinda BIOS means a hell old one...which is not suitable to fit with XP :unsure:

Have I lost the whole point or what...? :(
Because I wanna know how to use it and to know its advantage...

Thanks in advance. :)
