remove SONY VGN-B88GP keyboard and install sound driver

I was looking to the VGN-B88GP manual. I finally find the manual on a website. But the driver on SONY's website is not working for this model ( is there a desktop model of this notebook).

anyway back in 2005, I put a copy of drivers from CD on the D: drive. this comes handy today.

to remove the keyboard, un-do the screw at the back of the enclosure, then at the front of the keyboard, there are 3 retractable tab between those F-keys. use jewel tools gently push and prick open the keyboard from the enclosure.
