M.2 Sockets
The M.2 socket is the Next Generation Form Factor (NGFF) which is designed to support
multiple modules and make the M.2 more suitable in application for solid-state storage. The
board preserves space for the M.2 M key socket (22mm x 42mm, 22mm x 60 mm, and 22mm
x 80mm).
Mini PCIe
The Mini PCIe sockets allow for two full-size Mini PCIe modules. Mini PCIe 1 supports PCIe or
USB signals, while Mini PCIe 2 supports PCIe, SATA, or USB signals.
BIOS Setting
Configure PCIe root ports in the Advanced menu (“PCI Express Configuration” submenu) of the
BIOS. Refer to chapter 3 for more information.
Jumper Setting
Select the signal of Mini PCIe 2 via jumper settings as previously instructed in this chapter.
