This paragraph describes the register interfaces to the APM BIOS functions.

Functions are accessed through INT 15h.  The carry flag is set and an error code

is placed in the AH register when an error condition is detected.  The carry flag

is reset to zero upon return from successful calls.  The contents of the AH regisĆ

ter depend on the particular call.
This interface has a convention for identifying a device class and units within

that class to allow for direct control of devices.  For example, all disk devices are

a class and the units are the physical unit numbers.  The device ID parameter is

passed in a wordĆlength register (BX), where BH is the device class and BL is the

device unit.
