Add network and storage drivers manually
Move any drivers that are currently stored in the drivers directory to a different source or device to prevent conflict. When switching from a lower version of WinPE KBE to a higher version or conversely, remove any drivers that were downloaded from the Driver Feed because the drivers are similar. Also, to avoid slow deployments, remove drivers for devices that are no longer in your environment.The driver files from a manufacturer's site generally consist of .inf, .sys, and .cat files. There might be dependent files that the .inf file requires to load the drivers.
1. Access the drivers share directory of your appliance from the UNC (Universal Naming Convention) path \\<appliance>\drivers, where <appliance> is either the IP address or the DNS name of the appliance.
2.
3. Add the driver files to the folder that corresponds to the process to which you want to make the drivers available. For example, add the KBE_driver_pack/kbe_windows_x86 directory in to the corresponding kbe_windows_x86 directory on the appliance. Also, copy the contents of the KBE_driver_pack/kbe_windows_x64 directory in to the corresponding kbe_windows_x64 directory on the appliance.
