[ltp] Re: What to take care of when buying a Lenovo?

[Jeffrey Franc-Law]

My experience with x60, using the 945GM chipset (t7200 core 2 duo at 
2ghz) does NOT see all 4GB of RAM.  Bios shows all 4GB but 64bit linux 
does NOT.  It appears to see just over 3GB.  In my perusal of the 
internet, I have not seen anyone who go this to work.  Interestingly, I 
spoke to someone who had a Mac, it he say it was commen knowledge to Mac 
users that this chipset takes only 3gb RAM.

ciao,
