- smfd, floppy, floptical - driver for SCSI floppy and floptical disk
- drives

- This driver supports 5 1/4" floppy drives in 3 standard formats when used
- with the freestanding SCSI floppy drive. The standard single and double
- density dual sided 3 1/2" drive and the 3 1/2" 20.1MB floptical drive is
- also supported.
-
- The driver also supports a large range of special formats by use of the
- SSSSMMMMFFFFDDDDSSSSEEEETTTTMMMMOOOODDDDEEEE ioctl (defined along with the associated structure in
- /_u_s_r/_i_n_c_l_u_d_e/_s_y_s/_s_m_f_d._h).
-
- Most of the ioctls for the ddddkkkksssscccc also apply to this driver, with the
- exception of the bad block handling. The volume header ioctl DDDDIIIIOOOOCCCCGGGGEEEETTTTVVVVHHHH
- is supported by creating the structure based on the current driver
- parameters. The DDDDIIIIOOOOCCCCGGGGEEEETTTTVVVVHHHH ioctl is not supported. Individual tracks may
- be formatted using the DDDDIIIIOOOOCCCCFFFFMMMMTTTTTTTTRRRRKKKK ioctl and the fmt_map_info structure
- defined in /_u_s_r/_i_n_c_l_u_d_e/_s_y_s/_d_v_h._h. The SSSSMMMMFFFFDDDDMMMMEEEEDDDDIIIIAAAA ioctl is used to get the
- status of the floppy and the SSSSMMMMFFFFDDDDEEEEJJJJEEEECCCCTTTT ioctl is used to eject the floppy
- on a drive with the software eject mechanism.
-
- The standard devices (and suffixes) are the standard PC formats of 360KB
- (.48), 720KB (.96), 1.2 MB (.96hi) on the regular 5 1/4" device, and the
- standard 720 KB (.3.5), and 1.44MB (.3.5hi). The .3.5.20m suffix is for
- the 20.1MB 3 1/2" floptical drives and disks only.
-
- The special files are named according to the convention discussed in
- _i_n_t_r_o(7M), with the exception of ....ttttyyyyppppeeee, instead of ssss####:
-
- ////ddddeeeevvvv////{{{{rrrr}}}}ddddsssskkkk////ffffddddssss<<<<ccccoooonnnnttttrrrroooolllllllleeeerrrr----####>>>>dddd<<<<ddddrrrriiiivvvveeee----####>>>>{{{{....ttttyyyyppppeeee}}}}
-
-
- These devices can be used as filesystems, as backup devices, and for data
- interchange with other systems.
-
- Ordinarily, the devices may be opened by more than one process at a time,
- as long as all are opened at the same density. Attempts to open at a
- different density than which it is already open will fail.
-
- To manually access a disk, use mmmmoooouuuunnnntttt((((1111mmmm)))). mmmmeeeeddddiiiiaaaadddd((((1111mmmm)))) can also be
- configured to automatically mount a disk. New disks must be formatted;
- see mmmmkkkkffffpppp((((1111mmmm)))).

- The following errors are returned by this driver; other errors can also
- be returned by higher levels of the operating system.
-
- EAGAIN The drive returned an error indicating it was not ready (media
- ejected, and so on).
-
- EIO Some physical I/O error has occurred.
-
- ENXIO Device number doesn't correspond to a valid device.
-

- In previous releases, the flag OOOO____EEEEXXXXCCCCLLLL had special meaning to this driver
- when used on open; it is now ignored. For true exclusive use access, the
- _d_s(7m) driver should be used, with the OOOO____EEEEXXXXCCCCLLLL flag passed on open, where
- it will either complete the open with no other opens allowed, or will
- fail if the device is already open by any driver.
-
- An open will now succeed if there is no media in the floppy drive.
