Boot sequence

Hi
Can any one give a boot sequence.Is there any small BIOS stubb gets executed before the control is passed to MLO.
OR is there a hardwired logic implemented to follow boot sequence starting from MLO.

Thanks in Advance

Tilak,

Take a look at http://elinux.org/BeagleBoard#BootRom.

The OMAP has a hardwired internal boot ROM that normally tries to boot
from NAND Flash, USB, Serial, or MMC in that order. If you hold down
the USER button while resetting, the order is USB, Serial, MMC, NAND.
