Name: PI7C21P100 PCI to PCI Bridge

Chip used on Intel quad-port PCI-X NIC. Found specs at http://www.pericom.com/pdf/datasheets/PI7C21P100.pdf and http://www.pericom.com/pdf/datasheets/PI7C21P100B.pdf. Both specs use 01a7, should it be listed as PI7C21P100(B)?

The "classic" PCI is limited to 32-bit transfers and up to 33 MHz. All faster devices conform to the PCI-X specification.
