Thanks
That helped clear it up for me :).

You are confusing the specific case of the x86 PC architecture with the
general concepts here.
The OAL in Windows CE is the general equivalent to the BIOS in the desktop
systems. Since the PC architecture already has the BIOS for initialization
and the PC Architecture defines a very rigid fixed set of hardware
attached to the CPU (timers interrupt controllers, etc...) The OAL for a
PC is fairly generic and re-usable across most, if not all PC systems.
However, on RISC based CPUs (that are usually System On Chip (SoC)
devices) the story is completely different. They have no BIOS and have no
standardized architecture to rely on so they require custom OAL
development for each CPU and due to other technical issues usually for
each device design using a particular CPU as well.
