Subject: RK06/7 boot block bug (+fix) Index: sys/mdec/hkuboot.s 2.11BSD Description: The RK06/7 boot block enters an endless loop on the first I/O request. Repeat-By: Either attempt to boot a RK06/7 disc (sorry 'bout that Paul) or by inspection of the code. Fix: Apply the patch below. There was a 1 character typo, the wrong register was being used in the test for i/o completion. _---------------------------------------------------------------------- *** hkuboot.s.old Wed Apr 24 13:08:11 1991 --- hkuboot.s Thu Dec 12 15:52:05 1991 *************** *** 249,255 **** mov $WC,-(r3) / word count mov $iocom,-(r3) 1: ! tstb (r1) bge 1b / wait for iocom to complete mov (sp)+,r1 rts pc --- 249,255 ---- mov $WC,-(r3) / word count mov $iocom,-(r3) 1: ! tstb (r3) bge 1b / wait for iocom to complete mov (sp)+,r1 rts pc
