This article details the process for configuring your Douro's ACP-1103 tablet to run exclusively from a USB system drive instead of its internal drive.
Use this article after creating a bootable system drive.
Determining your model tablet
You can determine which model your tablet is by whether the USB port next to its power button is USB 2.0 (black) or 3.0 (blue). The ACP-1104 has one USB 3.0 port, the ACP-1103's are all USB 2.0.
This guide applies only to the ACP-1103 tablet. For the ACP-1104, please instead reimage its internal drive.
Entering the BIOS
Power off the Douro with a single press and release of the power button at the top of the tablet.
Insert the flashed USB drive into one of the USB ports on the top of the Douro's tablet and connect a USB keyboard to one of the tablet's other ports.
Press the tablet's power button, then repeatedly hit the DEL key on the keyboard until the tablet boots into the BIOS settings screen.
