Definition What is the the INF driver ,,, what is the benfit of it ?? thank you

Hi, I understand that you are unable to install Windows XP audio driver for your Compaq Presario 772TU Notebook.
This model was built with Conexant Audio and Modem Chip. For that, you may first need to install Microsoft UAA driver and then, install appropriate drivers.

Download and install UAA drivers from here:

ftp://ftp.hp.com/pub/softpaq/sp33501-34000/sp33867.exe

Conexant High Definition Audio Drivers here

ftp://ftp.hp.com/pub/softpaq/sp34001-34500/sp34200.exe

This will create a swsetup folder in c drive ("C:\swsetup\sp34200")
Installing Audio drivers may result in an error. But continue with the following steps to get the audio driver installed correctly.
Open the Device Manager:
1. Click on Start and select Run. Now type devmgmt.msc and press enter.
2. Right click on "Audio device on High Definition Audio Bus" and click Update driver.
3. Select "Install from a list or specific location"
4. Click Next. Then select "Don't search, I will choose the driver to install"
5. Click Next and then select "Sound, video and game controller" from the list.
6. Click Next and then click Have Disk.
7. Click Browse C:\swsetup\sp34200 folder and select the .inf (wis30b2a) file and click open and Continue with the onscreen instructions.

Similarly install Modem Drivers:
Download and install Conexant HDAUDIO Soft Data Fax Modem with SmartCP from here:

ftp://ftp.hp.com/pub/softpaq/sp33501-34000/sp33890.exe

1.Right click on "Modem device on High Definition Audio Bus" and click Update driver.
2. Select "Install from a list or specific location"
3. Click Next. Then select "Don't search, I will choose the driver to install"
4. Click Next and then select "Modem" from the list.
5. Click Next and then click Have Disk.
6. Click Browse C:\swsetup\sp33890 folder and select the .inf (wis30b2b) file and click open and Continue with the onscreen instructions.
