Huh. I knew that trick worked on the virtual TOD clock, but didn't know it would work on the real one. The VM initialization code for setting the time/date always seems to trigger the need for the HW console entry to enable writing to the real TOD clock. Learn something new every day, I guess. Do you need TODENABLE in the directory entry -- obviously anyone shouldn't be able to do this. I would like to see that code... -- db
