ventoy_geom kernel mod is used to boot FreeBSD and other Unix distros.
|
||||
This kernel mod need to build inside a FreeBSD system.
|
||||
|
||||
use VM to install a FreeBSD (e.g. 9.X/10.X/11.X/....), need to install source code.
|
||||
copy these files for example: Unix/ventoy_unix_src/FreeBSD/geom_ventoy_src/10.x/sys to /sys directory.
|
||||
cd /sys/modules/geom/geom_ventoy/
|
||||
make
|
||||
make install
|
||||
|
||||
Other distros are similar.
