DellPowerEdge R610 Technical Guide 349 BIOS9.1 OverviewThe R610 BIOS is based on the Dell BIOS core and supports the following features: Intel® Xeon® 5500 and 5600 processor series 2S support Simultaneous Multi-Threading (SMT) support Processor Turbo Mode support PCI 2.3 compliant Plug and Play 1.0a compliant MP (Multiprocessor) 1.4 compliant Ability to boot from hard drive, optical drive, iSCSI drive, USB key, and SD card ACPI support Direct Media Interface (DMI) support PXE and WOL support for on-board NICs Memory mirroring support SETUP access through 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 StatesThe Advanced Configuration and Power Interface is a standard interface for enabling the operatingsystem to direct configuration and power management.The Intel Xeon processor 5500 and 5600 series supports the following C-States: C0, C1, C1E, C3, andC6. The R610 supports all of the available C-States.9.3 I2C (Inter-Integrated Circuit)I2C is a simple bi-directional two-wire bus for efficient inter-integrated circuit control. All I2C-buscompatible devices incorporate an on-chip interface which allows them to communicate directly witheach other via the I2C bus. This design concept solves the many interfacing problems encounteredwhen designing digital control circuits. These I2C devices perform communication functions betweenintelligent control devices (e.g., microcontrollers), general-purpose circuits (e.g., LCD drivers,remote I/O ports, memories) and application-oriented circuits.
