INTERFACE COMMANDS

InitializationCommands

Identify Drive

Allows the host to receive parameter information from the drive.

When the command is received, the drive:

1.Sets BSY,

2.Stores the required parameter information in the sector buffer,

3.Sets the DRQ bit and

4.Generates an interrupt.

The host may then read the information out of the sector buffer. Parameter words in the buffer follow. Note that all reserved bits or words should be zeroes.
