script to update NC7781 driver DL server

[CA1150488]

i have tryed to update my proliants driver with those command:
cpqsetup.exe /s /force
i have 2 lan adapter configured
and this update has updated only one adapter to the 7.40
furthermore all the configuration has been lost and the server needs a reboot.
i have manually re-updated the old driver (named compaq) that was linking the same dll than the 7.40 ..
and now it is ok .

is there a way to update the driver without loosing the configuration and updating the twice adapters at the same time ? i would preffer without using insight ..
