• ACPI support

• Direct Media Interface (DMI) support

• PXE and WOL support for on-board NICs

• Memory mirroring support

• SETUP access through <F2> key at end of POST

• USB 2.0 (USB boot code is 1.1 compliant)

• F1/F2 error logging in CMOS

• Virtual KVM, CD, and floppy support

• UEFI 2.1 support

• Power management support, including DBS, Power Inventory, and multiple power profiles

• Intel TXT (5600 series)

• Intel AESNI (5600 series)

The R610 BIOS does not support the following:

• BIOS language localization

• BIOS recovery after bad flash (can be recovered from iDRAC6 Express)

9.2 Supported ACPI States

The Advanced Configuration and Power Interface is a standard interface for enabling the operating

system to direct configuration and power management.

The Intel Xeon processor 5500 and 5600 series supports the following C-States: C0, C1, C1E, C3, and

C6. The R610 supports all of the available C-States.

9.3 I

C (Inter-Integrated Circuit)

C is a simple bi-directional two-wire bus for efficient inter-integrated circuit control. All I

C-bus

compatible devices incorporate an on-chip interface which allows them to communicate directly with

each other via the I

C bus. This design concept solves the many interfacing problems encountered

when designing digital control circuits. These I

C devices perform communication functions between

intelligent control devices (e.g., microcontrollers), general-purpose circuits (e.g., LCD drivers,

remote I/O ports, memories) and application-oriented circuits.
