I need to boot an OpenServer 5.0.5 server but I don't have emergency boot disks for it. There are some boot disks of other servers.

Can I use these disks, changing defbootstr ?. How ?.

The fact is that administrator can't login as root and it seems to be a corrupted auth system issue. Other user can login.

We need to mount root partition to check shadow and other auth files, before reinstall.

Thanks.
