Fast CPU reset.
Fast CPU reset. A 0 to 1 transition activates a CPU reset. Detected in the 4041 for redirection to SMI.
7:1
IDE Controller Primary Address.
When the fast IDE is enabled at this address, 1F0 (byte, word, or double word access) activates the
internal IDE state machine. 1F0:1F7 generate IDECS0#. 3F6:3F7 generate IDECS1#. The data is
redirected to the IDE buffers.
IDE Controller Secondary Address.
When the fast IDE is enabled at this address, 170 (byte, word, or double word access) activates the
internal IDE state machine. 170:177 generate IDECS0#. 376:377 generate IDECS1#. The data is
redirected to the IDE buffers.
IDE Controller Third Address.
