Win98/ME...) should set S-ATA and P-ATA to Legacy Mode
• Maximum 4 ATA devices to connect under Combined mode or
Non-Combined mode
a Non-Combined Mode: S-ATA devices only - Maximum of 2 devices
b Non-Combined Mode: P-ATA devices only - Maximum of 4 devices
c Combined Mode: S-ATA devices and P-ATA devices - 2 devices each
(Maximum of 4 devices)
2 Native Mode
• System BIOS will search all available IRQs for HDD use
• New OSs that support Native Mode (Windows® XP
Professional, Windows® 2000) can set S-ATA and P-ATA to
Native Mode
• Comprehend both Legacy and/or Native Modes
