If the device is not a CD-ROM, 112or the table of contents cannot be examined, the filesystem will be 113started at sector 0. This option can be used to override the behaviour. 114Note that 115.Ar startsector 116is measured in CD-ROM blocks, with 2048 bytes each. This is the same 117as for example the 118.Cm info 119command of 120.Xr cdcontrol 1 121is printing. 122It is possible to mount an arbitrary session of a multi-session CD by specifying 123the correct 124.Ar startsector 125here. 126.It Fl v 127Be verbose about the starting sector decisions made. 128.El 129.Sh EXAMPLES 130The following command can be used to mount a Kodak Photo-CD: 131.Pp 132.Dl "mount_cd9660 -o rw -v -s 0 /dev/cd0c /cdrom" 133.Sh SEE ALSO 134.Xr cdcontrol 1 , 135.Xr mount 2 , 136.Xr unmount 2 , 137.Xr fstab 5 , 138.Xr mount 8 139.Sh BUGS 140POSIX device node mapping is currently not supported. 141.Pp 142Version numbers are not stripped if Rockridge extensions are in use. 143In this case, accessing files that don't have Rockridge names without 144version numbers gets the one with the lowest version number and not 145the one with the highest. 146.Pp 147There is no ECMA support. 148.Sh HISTORY 149The 150.Nm 151utility first appeared in 152.Bx 4.4 . 153
