Features ! One System PCI Slot, SYS, compatible with the PCI session of PICMG slot. ! Three onboard PCI Slots namely PCI1, PCI2, and PC3. " PCI1 is compatible with PCI#1 of PICMG (IDSEL=AD31) " PCI2 is compatible with PCI#2 of PICMG (IDSEL=AD30) " PCI3 is compatible with PCI#3 of PICMG (IDSEL=AD29) ! Supports ACPI function that enables the operating system to control the amount of power given to each device attached to the system. With ACPI, the operating system can turn OFF peripheral devices when they're not in use. Specifications are subject to change without notice. III.
