Item Type: Adapter Card Chipset: PXE8112 Compliant with PCI specification version 2.3 Compliant with PCI Express specification version 1.0 Support PCI slot 3.3V/1A, 3.3Vaux/100mA, 5V/5A and 12V/500m. PCI Express 1 channel port (1 virtual channel), 2.5Gbps. 1、The chipset PXE8112 is compliant with the PCI specification version 2.3. PCI 32-bit card for PCI Express x1, x4, x8 or x16. 2、Compliant with PCI Express specification version 1.0. PCI Express 1 channel port (1 virtual channel), 2.5Gbps. 3、No drivers are required, plug and play. Support PCI slot 3.3V/1A, 3.3Vaux/100mA, 5V/5A and 12V/500m. 4、The PEX 8112 supports forward and reverse switching as defined by PCI to PCI Express / PCI-X Bridge Specification 1.0. 5、In forward mode, the riser card allows legacy PCI chips and adapters to be used with new PCI Express processor systems. The reverse transfer operation allows legacy PCI processors and chipsets to configure and control advanced PCI Express switches and endpoints. 6、The PEX 8112 not only allows full configuration of downstream PCI Express systems from the PCI bus, but also handles limited PCI Express root functions for reverse interrupt and power management events.
