Does anyone have any idea what I should do next? BTW this all worked
with the old version of vnconfig, before it had a -t option...

% vnconfig -t floppy3 -v -c /dev/vnd0a ramdisk-12G.fs
vnconfig: /dev/rvnd0a: Device not configured
% ls -l /dev/*vnd0a
crw-r-----  1 root  operator   41,   0 Jul  2 13:01 /dev/rvnd0a
brw-r-----  1 root  operator   14,   0 Jul  2 13:01 /dev/vnd0a
% grep -i vnd /usr/src/sys/arch/i386/conf/QUARTZ
pseudo-device   vnd     4               # paging to files

Cheers,

 Patrick
