Holy crap... BTW I have some other compat. issues with USB legacy emu so I still use and prefer PS/2 KB and mouse (using PS/2 - USB adapter) so I have disabled it for most of time...

I think you can (some programms reprogram it speed for own purposes so disabling should be ok), if I remember there may be some issues with flopy drive and of course after you finis you should restore system time from CMOS RTC to keep it in sync.

BTW on what project are you doing? What HW do you RT control?
