You can select from the following two modes: Combined Mode and En- hanced Mode.
Combined Mode:
In this mode, system BIOS assigns the traditional IRQ 14 and IRQ 15 for the use of HDD. Up to 4 ATA devices are supported by this mode.
Within the Combined Mode, the following three modes are supported:
*Combined Mode: SATA devices and PATA: with the support of 2 devices
each (total: 4 devices maximum). (For IDE/SATA configurations, please refer to the table below.)

Enhanced Mode:
In this mode, system BIOS will automatically search for all available IRQs for the use of HDD. For newer Operating Systems that support the Enhanced Mode, such as Windows XP, Windows 2000, and Windows 2003, you can set SATA and PATA to the Enhanced Mode. (*The newer Operating Systems can accommodate both Enhanced Mode and Combined Mode and support up to 6 ATA devices.)
(*Please refer to the "Advanced Chipset Control" under the "Advanced" Setup in the BIOS for the selection of Combined Mode or Enhanced Mode,).
