USB 3.0
To support universal serial bus (USB) 3.0 in operating systems, set the extensible host controller interface (xHCI) XHCI
Hand-off option to enabled. Access this setting from the BIOS setup screen, select the Advanced tab, then select USB
Configuration.
If the BIOS must support USB 2.0 devices—legacy USB devices—leave Legacy USB Support set to enabled, shown below.
Because the box is connected using the universal asynchronous receiver-transmitter (UART) console, traditional keyboard or
mouse are not connected to the USB ports.

PXE and HTTP boot support
VEP4600 allows the platform to boot an operating system using Preboot Execution Environment (PXE) boot. To enable PXE
boot, set the Network Stack option to enabled. Access this setting from the BIOS setup screen, select the Adanced tab,
then select Network Stack.
The BIOS also supports hypertext transfer protocol (HTTP) boot. Use both HTTP and PXE boot over IPv4 or IPv6.
