Described is a personal computer system that includes a first housing coupled to a second housing with a multi-conductor cable. The first housing includes an IDE direct access storage device having an opening for receiving a removable storage medium. The second housing is separate from the first housing and includes a microprocessor coupled to a local bus and an expansion bus, a first IDE controller, a non-volatile storage device coupled to the local bus and a power supply. The cable is coupled to the first and second housings for electrically connecting devices in the first housing to devices in the second housing. The second housing has a first interface coupled to the expansion bus, the first IDE controller and the cable. The first housing includes a second interface coupled to the cable and the IDE device. The first interface is operative to (1) determine when a bus cycle initiated by a device in the second housing is directed to the IDE device in the first housing and (2) transfer data from the IDE controller to the IDE device via the cable and the second interface when a bus cycle is directed to the IDE device.

Local bus IDE architecture for a split computer system

Disclosed is a method for transferring data between at least one direct access storage device in a media console and devices in a system unit. The system unit is separate from the media console and includes a microprocessor coupled to a local bus and an expansion bus. An electrical connector having one end coupled to the media console and another end coupled to the system unit is used for electrically connecting device(s) in the console to devices in the system unit. The method includes the steps of monitoring the expansion bus with a first interface in the system unit to determine when a bus cycle initiated by a device in the system unit is directed to the direct access storage device and transferring data from the expansion bus to the direct access storage device via the electrical connector and a second interface in the console when a bus cycle is directed to the direct access storage device.

Method for interfacing a media console and a system unit

Disclosed is a personal computer system that includes a media console coupled to a system unit with a multi-conductor cable. The media console includes a direct access storage device having an opening for receiving a removable storage medium. The system unit is separate from the console and includes a microprocessor coupled to a local bus and an expansion bus, a non-volatile storage device coupled to the local bus and a power supply for supplying power to the system. The cable has one end coupled to the console and another end coupled to the system unit for electrically connecting devices in the console to devices in the system unit. The system unit has a first interface coupled to the expansion bus and the cable, and the console has a second interface coupled to the cable and the direct access storage device in the console. The first interface is operative to (1) determine when a bus cycle initiated by a device in the system unit is directed to the direct access storage device in the console and (2) transfer data from the expansion bus to the direct access storage device via the cable and the second interface when a bus cycle is directed to the direct access storage device.
