FreeBSD boot menu is missing

[Peter Steele]

I have a procedure for converting a FreeBSD box to use a mirrored slice
for the OS. Everything working fine except that after I've made the
conversion I am no longer getting the normal boot menu, the one that
counts down 10 seconds waiting for the user to pick on option. 

 

I see a single line showing that the BTX 1.01 loader has been launched,
but from there the system simply boots directly with no menu being
displayed. I'm obviously missing a step when using gmirror to convert a
system over to use mirroring but I'm not sure what. My basic approach is
to install the OS onto the first drive, setting it to use the standard
boot manager, and then setup the second drive using gmirror and copy the
file systems over to the mirror. I then set boot.config to boot off this
drive and it comes up fine, there just isn't any boot menu. 

 

Any advice on how to solve this would be appreciated. Thanks.
