Asus Media Bus

It was developed to provide a cost-efficient solution to a complete multimedia system.

Using Media Bus cards for building a system reduced slot requirements and compatibility problems.

[1] Expansion cards supporting this interface were only manufactured by Asus for a very limited time.

While similar to PCI-X in appearance, the extension contains 4 additional pins (2 on each side) for a total of 68.

The divider between the PCI slot and Media Bus extension is too wide to support a properly-keyed PCI-X card.
