Restrictions
EAD(PCI)BE, EAD(LPCI)BE has restrictions on the types of PCs and boards that can be used.
Be sure to check the following restrictions before use.
< Restrictions of PC>
- EAD(PCI)BE, EAD(LPCI)BE use the PCI-to-PCI Bridge to extend the bus.
The PCI boards plugged in PCI slots in the EAD(PCI)BE, EAD(LPCI)BE are recognized if the
PCI-to-PCI bridge is recognized by the BIOS in the PC used. Ask the PC vendor for whether the
BIOS recognizes the PCI-to-PCI bridge.
< Restrictions on transfer rate >
When the expansion chassis accommodates a board that performs high-speed transfer such as bus
mastering, the overall transfer rate may be lower than that of PCI bus slots in the main unit of a desktop
PC.
This is caused by bus extension by the PCI-to-PCI Bridge.
The transfer rate may vary with the system configuration and the type of the PC.
< Restrictions of PCI board>
None of the following types of boards can be used in any expansion slot in the expansion chassis.
- Video display board (VGA board)
- Board to connect a PCI bus expansion chassis
- Board explicitly stated not to be used with the PCI-to-PCI Bridge
- Some boards, even PCI-compliant ones, may not work depending on their specifications
