SATA Emulation Mode

The SATA emulation mode can be set in F10 Setup at

Storage > Storage Options > SATA Emula-

tion

. Default is AHCI.

The SATA emulation mode is set to AHCI by default. This differs from previous HP Compaq dc7xxx Busi-

ness PCs, which had a default SATA emulation mode of IDE (legacy).

While the eSATA port works in IDE mode, hot-plug functionality is not available. The SATA emulation

mode must be set to AHCI or RAID for hot-plug support. In addition, a hot-plug capable AHCI driver must

also be loaded in the operating system (see

“Software Drivers” on page 5

) for hot-plug support.

Note, that in IDE or AHCI mode, the system BIOS controls the hard drives so the Removable Media Boot

setting applies. In RAID mode, the RAID option ROM controls the hard drives so the Removable Media

Boot setting does not apply.
