Hi!

This morning, I installed this update :

NVIDIA Corporation driver update for NVIDIA nForce4 Serial ATA
Controller

Installation date: ?2007-?06-?19 07:59

Installation status: Successful

Update type: Optional

This driver was provided by NVIDIA Corporation for support of NVIDIA
nForce4 Serial ATA Controller

When I click on http://winqual.microsoft.com/support/?driverid=2007
I'm always redirected here
http://windowshelp.microsoft.com/Win...366261033.mspx
And, for any driverid number, it is the same thing.
I understand that this is the definition of the word "driver" and it is not
what I want.
I want to know the problem corrected by the update.

Do you know what is going on?
Do you know how to obatin the information concerning the driverid (what ever
the number)?

Merci beaucoup!
