ABSTRACT:
A computer system is described in which a table created in memory includes drive description data for one or more IDE devices included in the system. A command intercept circuit is described which intercepts device-identification commands and reroutes the device-identification operation to memory. The command intercept circuit includes an address decode circuit which asserts a first control signal upon decoding an address corresponding with the one or more IDE devices. A command decode circuit responds to the asserted first control signal to decode data and asserts a second control signal when the decoded data corresponds with a device-identification command. An address generator responds to the asserted second control signal to generate a memory address where the drive description data table is stored.
