Mirrored DIMM pairs must be the same size to allow selection of single-board mirrored memory or dual-board mirrored memory. Pairing different size DIMMs results in the following caution: Current memory configuration does not support Online Spare. USB Control The USB Control menu determines how USB ports and embedded devices operate at startup: • When USB Enabled is selected, all USB ports and embedded devices are enabled. • When USB Disabled is selected, all USB ports and embedded devices are disabled. • When Legacy USB Disabled is selected, all USB ports are enabled under a USB-aware OS, but USB is not supported during POST or RBSU. Legacy USB Disabled also disables iLO 2 virtual devices. RBSU menu (HP ProLiant G6 and earlier servers or server blades) 109

The Advanced ECC Support (maximum memory) setting disables additional resiliency and provides
the largest memory capacity to the OS.
The Online Spare with Advanced ECC Support setting requires a single group of spare modules and
provides automatic failover of degraded modules in the system while it is running.
The Mirrored Memory with Advanced ECC Support option provides protection against uncorrectable
memory errors that would otherwise result in system failure.
DIMM banks A and B are mirrored by
DIMM banks C and D on the same memory board. The failed memory can be replaced while the
system is running.
Mirrored DIMM pairs must be the same size to allow selection of single-board mirrored memory or
dual-board mirrored memory. Pairing different size DIMMs results in the following caution:
Current memory configuration does not support Online Spare.
USB Control
The USB Control menu determines how USB ports and embedded devices operate at startup:
When USB Enabled is selected, all USB ports and embedded devices are enabled.
When USB Disabled is selected, all USB ports and embedded devices are disabled.
When Legacy USB Disabled is selected, all USB ports are enabled under a USB-aware OS, but USB
is not supported during POST or RBSU. Legacy USB Disabled also disables iLO 2 virtual devices.
