Thank you...

Somebody can help me to understand the last 3 lines in the [AD4] driver,
and the last 2 lines in the [C2] driver.
I am to make a BartPE CD, and want to try to understand how the DriverPack works,
because I want to build a BartPE with Windows Xp-SP2, and another one with
Windows 2003 Server-Sp2, and I am interested in particular at the 2 following MassStorage drivers,
and I dont now if the 2 drivers works fine in BartPE with XP and Win 2003 Server.

1-If I put a driver for Win XP in a BartPE with Win 2003 Server what happens?

2-How can I now if a driver in 'DriverPack' is for Win XP, or Win2003Server?

3-what it means the lines:       ms_1_isBusExtender=false   
                ms_1_exc_disableIfOS="w2k"
                ms_1_exc_replaceIfOS="wxp,w2k3"

            and

                ms_1_exc_skipIfOS="w2k".

Thanks
