Use Deployment Solution for Dell Servers 2.0 SP1 to add Arbitrary Drivers to Scripted OS Install
Deployment Solution for Dell Servers version 2.0 SP1 has a feature that allows you to integrate any arbitrary driver into a scripted OS install. Using this mechanism is compatible with driver auto detection as well.
Step 1: Download a driver from the Dell Web site for your server. Save it locally to your computer.
Step 2: Go to Tools->Dell Tools->Configuration utility. Go to the OS Deployment Tab, and press "ADD".
You'll notice a section "Add a driver from another source". If the driver you are adding is a mass storage driver, change the "driver type" to "mass storage". Otherwise, leave it as "plug and play".
Note: Only mass storage drivers are "auto-detected" meaning they will only be copied if the server requires it. Plug and Play drivers will be copied down to the server regardless of whether it needs it or not.
Click on "Add from Other Source", browse to the necessary file (inf file in the case of plug and play, txtsetup.oem in the case of mass storage drivers).
You're done, now feel free to deploy machines.
