-The CPi-C/G/J/S panel PCs can boot from a USB drive.  Therefore, it is possible to boot from a ComfilePi OS installed on a USB drive, and from there, flash the SD Card/eMMC/NVME drive locally.  This method is **//much//** faster than writing the OS image to the ComfilePi over a USB cable.

   - Copy the OS image you wish to write to the ComfilePi's boot device to a directory on the USB drive using one of the following methods:
