We have A/UX version 2.0 running on a CI with 8 megs and EtherPort II ethernet card with version 1.1 driver. All fine. After experimenting with network subnetting I can't restart the machine. I have tried to restore the configuration files for domainname and netaddr. According to boot messages the network configuration seems ok again. During boot process everything seems fine; all commands in /etc/rc are executed without errors. After this the mouse hangs, garbage is displayed in menubar. I have the A/UX console up during boot, but the garbage described above doen't appear in console window. I have also tried to boot the machine with launch -sv (verbose option), but then the machine restarts instead of halting. Is there any way to start vi before launch command (I have noticed the ed command but doesn't know the ed commands) so that I can edit files? Is there any way to boot the machine in single-user mode? Any help appreciated. +------------------------------------------------------------------------------ | ANDERS ULFHEDEN | USENET: ULFIS@NADA.KTH.SE | ROYAL INSTITUTE OF TECHNOLOGY | STOCKHOLM, SWEDEN -- +------------------------------------------------------------------------------ | Anders Ulfheden | USENET: ulfis@nada.kth.se | Royal Institute of Technology

Look in the manual A/UX Text Editing Tools. It should be no problem because you will only need a few commands like print, substitute, write and quit or so. Do you use a color screen witb your Mac? If so, you should change the monitoir control panel to black and white in order to read the "garbage" in your menubar. To boot in single user mode, you also have to use the ed editor from the Startup application. change the line is:2:initdefault to is:s:initdefault, that is not multiuser (2) but singleuser (s). This should be reversed later. Another idea is to use the autorecovery partition each time before you implement some critical changes for saving a copy of the old file. Use eupdate and eu for this. Make your changes, reboot and if your system then refuses to boot, use the esch utility to resote the old state. So far, Kurt-- Kurt Rindle rindle@informatik.uni.ulm.de
