| FS_INSTALL (0xF001) |
This mode installs a new file system. name must be 'U:\' and arg should point to a fs_descr? structure as follows: struct fs_descr { FILESYS *file_system; WORD dev_no; LONG flags; LONG reserved[4]; }; If this call is successful, a pointer to a kerinfo? structure is returned, otherwise the return value is NULL. The file system itself is not accessible until this call is made and it is mounted with FS_MOUNT. |
| FS_MOUNT (0xF002) |
This mode mounts an instance of an installed file system. name should be in the format 'U:\???' where '???' is the name which the file system will be accessed by. arg should point to the fs_descr? structure as above. If the file system is mounted correctly, the dev_no field will be updated to reflect the instance number of the mount (file systems may be mounted multiple times). |
| FS_UNMOUNT (0xF003) |
This mode unmounts an instance of a file system. name is the name of the file system in the form 'U:\???' where '???' is the name of the file system instance. arg should point to the file system fs_descr? structure. |
| FS_UNINSTALL (0xF004) |
This mode uninstalls a file system identified by the fs_descr? structure passed in arg. A file system can only be sucessfully uninstalled after all instances of it have been unmounted. name should be 'U:\'. |

| DEV_INSTALL (0xDE02) | This command attempts to install a device driver. name should be in the format 'U:\DEV\???' where '???' is the name of the device to install. arg is a pointer to a dev_descr? structure as follows: struct dev_descr { /* Pointer to a device driver structure */ DEVDRV *driver; /* Placed in aux field of file cookies */ WORD dinfo; /* 0 or O_TTY (0x2000) for TTY */ WORD flags; /* If O_TTY is set, points to tty struct */ struct tty *tty; /* Reserved for future expansion */ LONG reserved[4]; } If the device is successfully installed, Dcntl() will return a pointer to a kerinfo? structure which contains information about the kernel. On failure, Dcntl() will return NULL. See the section on loadable file systems? for more information. |
| DEV_NEWTTY (0xDE00) | This command identifies a BIOS terminal device whose name is name (in the form 'U:\DEV\DEVNAME' and whose device number is arg. This call simply makes the MiNT kernel aware of the device. It should have been previously installed by Bconmap()?. Any attempt to access the device prior to installing it with the BIOS will result in an EUNDEV (-15) unknown device error. If the device is installed, Dcntl() returns a 0 or positive value. A negative return code signifies failure. |
| DEV_NEWBIOS (0xDE01) | This command is the same as DEV_NEWTTY except that it is designed for devices which must have their data transmitted raw (SCSI devices, for example). |
