The BIOS starts goes through the post and hardware configuration and what not and then attempts to find a boot device. Depending on the boot priority if there is no floppy or CD the BIOS will look at cylinder 0, head 0, sector 1 of HD one. The BIOS will pass control over to the OS. Now my question is, is there suppose to be some distinct instruction at cylinder 0, head 0, sector 1 like a jump or can the OS's code just start there?
