Note*1 Support PCIe bifurcation for RAID on CPU function.

*2 The PCIEX16_3 shares bandwidth wih M.2_3. When M.2_3 runs x4 mode, PCIEX16_3 will be disabled. When M.2_3 and PCIEX16_3 are both occupied, M.2_3 runs x2 mode, PCIEX16_3 runs X1 mode.

*3 The PCIEX1 shares bandwidth with M.2_1. When M.2_1 runs x4 mode, PCIEX1 will be disabled.

*4 M.2_1 shares bandwidth with PCIEX1. When PCIEX1 is occuppied, M.2_1 runs x2 or SATA mode (when M.2_1 runs SATA mode, SATA6G_2 will be disabled).

*5 M.2_2 shares bandwidth with SATA6G_56. When M.2_2 runs x4 mode, SATA_56 will be disabled. M.2_2 runs x2 mode by default.

*6 M.2_3 shares bandwidth with PCIEX16_3. When PCIEX16_3 runs x4 mode, M.2_3 will be disabled. When M.2_3 and PCIEX16_3 are both occoppied, M.2_3 runs x2 mode, PCIEX16_3 runs X1 mode.
