PEX 8112 supports forward and reverse bridges as defined by the PCI to PCI / PCI-X Bridge Specification 10.In forward mode, the bridge allows legacy PCI chips and adapters to be used with the new PCI processor system. Reverse bridge operation allows traditional PCI processors and chipsets to configure and control advanced PCI switches and endpoints.In contrast, the PEX 8112 not only allows downstream PCI systems to be fully configured from the PCI bus, but also handles limited PCI root functions for reverse interrupt and management events.specification:Chipset: PXE8112Compliant with PCI Specification Version 23PCI 32-bit card for PCI x1, x4, x8 or x16PCI 1 port (1 virtual ), 25GbpsCompliant with PCI Specification Version 10Combination low profile PCI 32-bit host cardSupport PCI slot 33V / 1A, 33Vaux / 100mA, 5V / 5A and 12V / 500mPlug and playapplication:Windows Server 2000 / NT / XP / Vista / Win 7, LinuxAvailable PCI slotsColour:GreenMaterial:metalSize:131 x39mmPackage Contents:1 x conversion cardOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
