8042 EMULATION

Now, there are many PC designs with a special

feature for OS/2 optimization. It is intended to speed up

the protected mode switching operation which is done by
the slow speed keyboard controller in the original PC

design. However, this feature often causes compatibility
problem because they use different hardware logic

design to bypass the keyboard controller. Thus, the BIOS
is needed to be modified to take advantage of it. An

application without modification may cause problem.

In HIPPO II, there are some logic designs in the

chipset to emulate the keyboard controller. An

application can work in the usual way to send commands
to keyboard controller, but these commands are in fact

interpreted by the chipset. The protected mode
switching operation is much faster. There will be no

potential problem since modification of software is not
needed.
