It seems the Kernel clear 0x0--4k.
Of course after itself take the MP TABLE.

Maybe need to update the kernel.

Eric,
Under 4G RAM  linusbios_tables occupy 0x500-0xae0, cmos_util can find
option_table even after rebooting.
Under 6G RAM linuxbios_tables occupy 0x500-0xaf4, cmos_util can find
option_table after power on but can not find it after rebooting.

The only difference should be that rebooting don't execute auto.c again.

Any advise.

Regards

Yingahi Lu

Ron,

I have verfied that if I disable the XIP... in old config tool, the image
produced will make the option table not accessiable after reboot too.

yuck. I always thought it left that page alone, since it's page zero 
anyway.

Well, that explains a thing or two.

I really need a working PIRQ (don't ask) so I'm going to take a stab at 
generating one from the linuxbios tables, unless somebody else has 
done/wants to do it.

I don't know if it is helpful to what you need or not, but there is code 
in the stpc section that builds a PIRQ table: 
(freebios/src/mainboard/stpc/consumer2/mainboard.c).  This uses the 0x0f 
router code which is a way around linux if it does not know about the 
router in your north/south bridge.  There are comments in the code.

That's what I love about this list. Everytime I ask a question it gets
answered in a work-saving way. Steve, I'll take a look at your stuff, and
thanks.

I am much relieved ...
