Then you need to get the final release, since beta4 had bugs in the RMCB locking code. You also need to do some checking to see if the interrupt you are using is free, since the primary interrupt PIC may sometimes be revectored to the 0x80 area! Checking to see if int 0x80 and 0x81 have the same seg:off is a good check.
