Floppy and CD-ROM drives
|
||||
========================
|
||||
|
||||
The *Floppy and CD-ROM drives* page contains settings related to the emulated machine's base removable devices.
|
||||
|
||||
Floppy drives
|
||||
-------------
|
||||
|
||||
Up to four floppy disk drives can be attached to the emulated system, although not all BIOSes provide support for more than two drives. The following options apply to the selected drive:
|
||||
|
||||
* **Type:** Type of floppy drive to emulate. Some drive types have special properties:
|
||||
|
||||
* **5.25" 1.2M PS/2** and **3.5" 1.44M PS/2:** IBM PS/2 drives, which have inverted polarity on the Density Select pin.
|
||||
* **5.25" 1.2M 300/360 RPM** and **3.5" 1.44M 300/360 RPM**: "3-mode" drives, which are capable of reading 360K 5.25" or PC-98 3.5" disks. BIOS support for 3-mode floppy drives is required.
|
||||
* **3.5" 1.44M PC-98:** NEC PC-98 drives, which are 3-mode and have inverted polarity on the Density Select pin.
|
||||
|
||||
* **Turbo timings:** Run the drive mechanism as fast as possible. This decreases access time and makes some incorrectly-dumped floppies readable, but may cause issues some operating systems and applications.
|
||||
* **Check BPB:** When disabled, 86Box will skip checking the `DOS BIOS Parameter Block <https://en.wikipedia.org/wiki/BIOS_parameter_block>`_ when determining the physical media format for a floppy image on this drive. See :ref:`usage/diskimages:Floppy disk detection` for more details.
|
||||
|
||||
.. note:: Disabling "Check BPB" may be required in order to access UNIX/Linux installation floppies or other raw stream disks, as outlined on the page linked above.
|
||||
|
||||
Floppy disk images can be inserted and removed through the status bar or the *Media* menu.
|
||||
|
||||
CD-ROM drives
|
||||
-------------
|
||||
|
||||
Up to four CD-ROM / DVD-ROM optical disc drives can be attached to the emulated system. The following options apply to the selected drive:
|
||||
|
||||
* **Bus:** bus to attach the drive to. ATAPI (IDE) and SCSI are supported.
|
||||
* **Channel**/**ID:** where to attach the drive on the selected bus. See :ref:`settings/hdd:Adding a new disk` for more information on IDE channels.
|
||||
* **Speed:** maximum transfer speed for the drive. Up to 72x is supported.
|
||||
|
||||
CD-ROM / DVD-ROM disc images can be inserted and removed through the status bar or the *Media* menu.

Other removable devices
|
||||
=======================
|
||||
|
||||
The *Other removable devices* page contains settings related to the emulated machine's additional removable devices.
|
||||
|
||||
MO / ZIP drives
|
||||
---------------
|
||||
|
||||
Up to four Magneto-Optical and four Iomega ZIP disk drives can be attached to the emulated system. The following options apply to the selected drive:
|
||||
|
||||
* **Bus:** bus to attach the drive to. ATAPI (IDE) and SCSI are supported.
|
||||
* **Channel**/**ID:** where to attach the drive on the selected bus. See :ref:`settings/hdd:Adding a new disk` for more information on IDE channels.
|
||||
* **Type** (MO only): drive model to identify as. A list of real drive models is provided.
|
||||
* **ZIP 250** (ZIP only): enable the drive to read and write 250 MB ZIP disks.
|
||||
|
||||
MO / ZIP disk images can be inserted and removed through the status bar or the *Media* menu.

Floppy disk detection
|
||||
---------------------
|
||||
|
||||
86Box detects the physical media format (sides, tracks per side, sectors per track, bytes per sector) of a floppy disk image through the following methods:
|
||||
|
||||
1. Data stored in the file header, except for Raw and DiskDupe formats where there is none.
|
||||
2. Data stored in the `DOS BIOS Parameter Block <https://en.wikipedia.org/wiki/BIOS_parameter_block>`_.
|
||||
3. If all else fails, a guess is made based on the file size.
|
||||
|
||||
The BIOS Parameter Block detection may result in incorrect behavior on *raw stream* (non-DOS) floppy disks. Installation floppies for UNIX and Linux are common examples of *raw stream* disks. Disabling the :ref:`settings/floppycdrom:Check BPB` option is strongly recommended for accessing these, as the inaccurate BPB detection may result in read errors, data corruption and other issues.
|
||||
|
||||
.. note:: When using a raw image of a raw stream floppy with the Check BPB option disabled, make sure the image file has the right size for its media type, otherwise incorrect behavior may still occur.
