yaboot architecture

[Raghu]

Hello All, 
Thanks for the explanations on "yaboot", what I
understand here is that 'yaboot' dosent have most of
the platform specfic code to execute from "poweron"
state and instead dependes on OpenFirmware to do it. 

OpenFirmware does the platform initializations ( SDRAM
init, Stack setup, North Bridge - South Bridge
initializations, PCI, IDE controller setup etc ) and
gives control to 'yaboot'

In turn this 'yaboot' code will read the Master Boot
Record from Hard Driver or CD Driver and boot Linux
OS.
I am not sure if my understanding is still correct.

Warm Regards,
Raghu.
