Abstract
A computer-readable media for transmitting data from a computer system comprising a processor, a bus with at least a first address for which no device is available and an element connected between the processor and the bus is provided. Computer-readable code for sending a message from the controller to the first address where no device is available, wherein the sending of the message prepares the element connected between the processor and the bus is provided.
Claims18
A method of exchanging data between a device and a bridge comprising a processor, a controller controllably connected to the processor, a buffer memory controller connected to the processor and the controller, and a bus connected between the controller and the device, wherein the bus has a first address which is the address of the device and a second address where no device is available and wherein the controller is able to automatically process commands in a first format and the device is able to process commands in a second format different than the first format, the method comprising:
- sending a manual command in the second format from the controller over the bus to the first address wherein the controller ignores the manual command and the device receives the command;
- converting the command into a converted command in the first format;
- and
- automatically sending the converted command from the controller over the bus to the second address wherein the controller uses the automatically sent converted command to prepare for an automatic data transfer and wherein the device ignores the converted command sent to the second address.
