			Fixed problems
			--------------

This version solve the "Clipper" problem;
"POL_LITE.EXE" use INT 15 function 86h "wait time" to test system timer (cause by IRQ0).
Because Phoenix Bios 4.0 release 4.04 has a bug about INT 15h function 86h wait event,
cause wait time is shorter than desired one.
