Something I am missing, and I have no idea right now how to correct this. I have a 10.4.11 Xserve with two drives, cloned nightly. On the first drive I installed 10.5.4 from a DVD (keeping the clone damned safe of course) When I rebooted of course it goes to the screen and asks for the serial number, which I have, but the keyboard will not work. The mouse does however. I downloaded the 10.5.8 combo updater to the cloned drive, but the installer bounces once and quits. I SUSPECT, but am not sure, it won't run from 10.4.11, and the server needs 10.5.8 to work correctly. The server is the last G5 model. My next plan of attack is to boot in target disk mode and install 10.5.8 combo update from a laptop to see if that fixes it. If THAT fails I have little recourse but to do either put it on a different server which will require me to do an incredibly tedious transfer of library software (Alexandria), or stick with 10.4.11 and forgo the nifty new features of the software. I can also try headless ARD using blank password and serial number. I was wondering if anyone had any insight as to why the KB refuses to work when the mouse does.
