OpenBIOS to replace outdated laptop bios

Hi folks,

I found this project looking for ways to add 48bit LBA support to an x86 
laptop. The laptop was manufactured ~2005 give or take to the best I can 
tell. Anyway, it will not recognize more than 137GB of a hard drive (tested 
with a brand new 250GB WD drive). The company that produced the laptop says 
they will not provide anymore bios updates for it and they also said they 
will not release any information or specifications regarding the motherboard 
so that leaves me with very few options for attempting to address this 
problem. The bios installed on it now is Phoenix 4.0 release 6 and it has no 
serial numbers or anything that I've been able to find to help identify the 
manufacturer of the motherboard, in fact, I'm starting to think the board 
was built by the company who sold the laptop. Based on my research, the 
laptop comes from a company called clevo who resells to companies that 
rebrand the computers. With that said, I'm wondering if the OpenBIOS project 
can help me to address the problem I've described.

Thanks for any information,
J.P.

Open-Bios on a compaq R4000?

Hello,
I have a compaq R4125CA with an AMD 3800+ CPU on socket 939.  I would
like to put in an AMD 4000 X2, but unfortuantely there is no bios
support to activate the second core.  I have read of other people
putting a dual core processor in this same model and having it operate
with just one core. Does anyone know what the possability of getting
open-bios running on this system would be and activating the second
core that way? Also, would it be possible to write a hook or patch the
existing compaq bios to activate the second core?  Maybe some code
executed pre OS boot, like in the boot loader?  I'm not sure how
involved it would be to activate the second core, if tables must be
set or just registers set, etc?  I've been toying with this notion for
awhile and have recieved some discouraging comments of the laptops
ability to handle the heat dissipation, but I think it can handle it
witha  few updates to the thermal module and some high quality thermal
paste.  I'm not too concerned about battery life.
Thanks,
Spencer
