remark
* 1. PCIEX1_1 Bandwidth sharing with USB 3.1 Gen 2 front ports (U31G2_E1). The default is off.
PCIEX1_2 share bandwidth with SATA6G_7.
* 2. When using a 28-channel CPU, SATA6G_5 &SATA6G_6 share bandwidth with PCIEX16_3.
* 3. When using an M.2 SATA device, the M.2_1 slot shares bandwidth with the SATA_2 interface. Adjust the BIOS settings to use the SATA device.
