Dima and list, I misstated, Dima is correct, and thanks to him, I discovered a few things I had not seen before. In order to verify what Dima was saying, I first tried to delete the good kernel (so I could make sure it was booting kernel.old), but the 'permission' on kernel would not allow me to do this. I built a new kernel and tried to boot the old one using the method I described below and it failed. HOWEVER, I was able to use the boot floppy to get back into the system: >>>boot dva0 [no flags] # mount /dev/da0a / # swapon /dev/da0b # cd /usr/src/sys/alpha/conf # ifconfig de0 192.168.1.19 # ftp to the P2 'put' my kernel configuration, vi it, 'get' it, compile a new kernel, and boot it. So, there is a way, to get back one's system and, in conclusion, adding boot.conf, at this time, may not be a good idea. My apologies if I created some confusion and another THANKS to Dima for pointing this out. curtis wrote: > > Hi Dima, > > (smile) not necessarily 'screwed' - One can: > > boot dka0 -file kernel.old > > and enter (^D) control D at the prompt to get back the previous kernel > > allowing one to telnet to back to the 'target' machine and make correct- > ions as necessary. > > In my case, before I build a new kernel, I copy the 'working kernel' to > another file name - (smile) just in case my new kerenl breaks something > and can boot it, using the above method. > > good luck and have fun, curtis > > Dima Ruban wrote: > > > > curtis writes: > > > I found that putting boot.conf in /boot (on the Multia) will speed up > > > the hard disk boot process and eliminates having to press enter or wait > > > for a countdown.
