Since the "IBM compatible" method to exit protected mode requires a hardware reset (ala 80286), this can be a time consuming operation. Switching back and forth from real and protected mode can indeed cause very slow keyboard response when operating in non-dedicated fileserver mode which is why, for example, the ZDS Z-386/20/25 is Novell certified for non- dedicated mode only when the OS is patched to take advantage of a specific hardware dependent fast reset feature. This patch is available from Novell's NetWire or the ZDS bulletin board --- see your dealer to see if something similar is available for your system. Pat Crean
