Key: SC = Sector Count Register
SN = Sector Number Register
Y indicates that the register contains a valid parameter for this command; for the
Drive/Head Register, that the drive uses both the drive and head parameters.
D indicates that only the drive parameter is valid, not the head parameter.
D* indicates that the host addresses the parameter to Drive 0, but both drives
execute the command.
Where a parameter is blank, the command does not require the contents of the register.
CY = Cylinder Register
DH = Drive/Head Register
