Centos Broadcom wireless & VGA installation on Laptop
 

I am very new to Linux. I installed Centos 5 in my pc, a laptop HP 6720s. It’s having intel Core 2 Duo Processor and 1 GB ram. Everything in Linux works fine except two things.
1.When I start the X windows , it’s not fit in the screen, The two sides of the screen is cropped. I try to play with the resolution but there is only one value 1024 x 768

My VGA card is Intel mobile GME 965/GLE 960(From lspci), I think the driver is not properly installed.

2. I was not able to install my Wireless Which is Broadcom BCM94311MCG wlan-mini-PCI


Please Send me the links to download these drivers and step by step instruction to install these(as I am not familiar with linux)
