For the truly dedicated disk case, you can select `No' at the
compatibility prompt. In that case, all BIOS geometry considerations
will no longer be in effect and you can safely ignore any
``The detected geometry is invalid'' warning messages you may later
see. It is also not necessary in this case to set a slice bootable
or install an MBR boot manager as both things are then irrelevant.

to the Master Boot Record) and extend to the very last sector of the
disk medium. Needless to say, such a disk cannot have any sort of a
boot manager, `disk manager', or anything else that has to interact with
the BIOS. This option is therefore only considered safe for SCSI disks
and most IDE disks and is primarily intended for people who are going to
set up a dedicated FreeBSD server or workstation, not a typical `home PC'.
