JIDA16 and JIDA32

JIDA16 (JUMPtec® Intelligent Device Architecture) is a BIOS interface which allows programs running in Real Mode
operating systems (i.e. MS DOS) to call certain functions implemented in the BIOS. These functions can be used to get
module information, make settings and access the I2C Bus and the Watchdog unit. JIDA16 functions are INT 15h BIOS calls
which are only available in 16 Bit Real Mode operating systems.

For 32bit operating systems (i.e. WindowsXP, Windows 7, Windows CE, VxWorks, Linux) a different JIDA implementation
called JIDA32 is implemented. The same common driver for all JIDA32 capable modules talks to the JIDA32 part in the
BIOS, which is hardware dependent to interact with the hardware.
