UEFI replaces the basic input/output system (BIOS) and defines a standard
interface between the operating system, platform firmware, and external devices.
UEFI-compliant servers are capable of booting UEFI-compliant operating
systems, BIOS-based operating systems, and BIOS-based adapters as well as
UEFI-compliant adapters.
Note: This server does not support DOS.
The Integrated Management Module (IMM) combines service processor
functions, video controller, and (when IMM Premium is installed) remote presence
function in a single chip. The IMM provides advanced service-processor control,
monitoring, and alerting function. If an environmental condition exceeds a
threshold or if a system component fails, the IMM lights LEDs to help you
diagnose the problem, records the error in the event log, and alerts you to the
problem. IMM Premium provides a virtual presence capability for remote server
management capabilities. The IMM provides remote server management through
industry-standard interfaces:
– Intelligent Platform Management Interface (IPMI) version 2.0
– Simple Network Management Protocol (SNMP) version 3
– Common Information Model (CIM)
