You can enable the Intel
®
VT in the BIOS Setup. The default setting is disabled.
Note: If the setup options are changed to enable or disable the Virtualization Technology setting
in the processor, the user must perform an AC power cycle before the changes take effect.
The Intel
®
IOH 5500 chipset on the Intel
®
Server Board S5500BC supports Intel
®
VT-d2 features
as outlined:
Builds on the first generation of Intel
®
VT-d features

PCI and PCI Express* Interfaces
The Intel
®
ICH10R provides a 33MHz, 3.3 V PCI interface implementation. All PCI signals are 5
V tolerant except PME#. The Intel
®
Server Board S5500BC provides one slot for legacy PCI
devices. This 5-V keyed slot can support Universal or legacy 5-V keyed PCI 32-bit / 33MHz add-
in cards.
