use of HDD. Up to 4 ATA devices are supported by this mode.
Within the Combined Mode, the following three modes are supported:
*Non-Combined Mode: Parallel ATA only:with the maximum of 4 devices
supported;
*Non-Combined Mode: Serial ATA only:with the maximum of 2 devices
supported;
*Combined Mode: SATA devices and PATA: with the support of 2 devices
each (total: 4 devices maximum). (For IDE/SATA configurations, please refer

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.)
