We have the problem.
In first, we have loaded the driver (F6) from the USB Key. Driver have been Loaded. Partition created, but with 'E:' letter (C: are used by usb key).
By reboot whithout USB key initialy and restart install, C: are assigned to Partition (whith F6, Insert USB Key, .....)
But during the windows install, windows need the driver from the "A: Disquette" !!
I am trying by using Bootable CD whith emulation of A: Drive, and lauch Win Install from a second CD Drive.
The best solutions are a Win2003 SBS CD whith raid Driver ! (HP, we need your help !)
