Jumping to LinuxBIOS

Hi,
Do I need to initialize the PAM (Programmable Attribute Map Register)?
Actually this register is used to do some memory mapping functionality.
When I was browsing the source code tree (in 440gx also) I found that in
all the Northbridge raminit.inc , we are setting this register to
default values (i.e., 0x00)
That means we are not worrying about the PAM during the RAM
initialization. Is my assumption is correct?
Thanks,
Siva
