(6)Cylinder High Field (exp)

The contents of this field indicates high-order 8 bits of the disk-access start cylinder address.

At the end of a command, the contents of this field are updated to the current cylinder number. The high-order 8 bits of the cylinder address are set to the Cylinder High Register.

Under the LBA mode, this field indicates LBA bits 23 to 16. Under the LBA mode of the EXT system command, LBA bits 47 to 40 are set in the Cylinder High Field, and LBA bits 23 to 16 are set in the Cylinder High Field (exp).

(7)Device/Head Field

The contents of this field indicate the device and the head number.

When executing INITIALIZE DEVICE PARAMETERS command, the contents of this field defines “the number of heads minus 1” (a maximum head No.).
