Same here. I upgraded from RELENG_3_0_0_RELEASE (the cd 3.0 release) to a cvsup done on 1/1/1999. It works, but see below. (I've worked in large commercial software projects, and your accomplishments here make me somewhat embarrassed to have been paid so well. I know that for some of you this is "just a hobby" you love to do.) Carlos C. Tapang http://www.genericwindows.com >I just completed an upgrade from a 9/1998 -current to 1/2/1999 elf >-current.

There's no way to tell that what you really have in /boot are the elf capable boot blocks. Test it first on a floppy. In my case, I disklabeled a floppy and pointed boot.config to 1:da(0,a)kernel because my elf kernel is in my SCSI drive. > >5. reboot > >6. build a new kernel and install it > cd /sys/compile/<kernel name> > make clean > make KERNFORMAT=elf depend > make KERNFORMAT=elf > mv kernel kernel.elf > install -c -m 555 -o root -g wheel -fschg kernel.elf / My kernel would not fit in a floppy, so I could not test this first using a floppy.
