Disk drive emulation has the fallback order
- true drive emulation (TDE)
- disk image emulation
- file system access, or
- raw /dev/fd0 device access, or
- real IEC device access via OpenCBM.
In detail:
- Drive #. model must not be None. (None = no drive. Stop.)
- If TDE is enabled, this is used. No image attached = empty drive.
- These options are relevant:
- Drive sound emulation
- Drive #. model / * (must not be None)
- Drive #. options / Read only access
- Drive #. expansion / *
- Drive #. 40-track image support / *
- Drive #. idle method / *
- Note that if TDE is enabled, and you want to use disk files, then Enable Virtual devices should be disabled, otherwise there are buggy side-effects (see Bug #580). Unfortunately, to use a printer, this option should be enabled...
- Otherwise (if no TDE)...
- Enable Virtual devices must be enabled (otherwise there is no drive. Stop.).
- If a disk image is attached to the drive, this disk image is used, regardless of the selection in Drive #. device type.
- These options are relevant:
- Drive #. options / Read only access
- Drive #. 40-track image support / *
- and this action:
- Attach disk image / Unit #....
- Otherwise...
- Drive #. device type = None -> no drive. Stop.
- Otherwise... (no disk image is attached)
- Drive #. device type = File system access -> directory is accessed
- sets resource FileSystemDevice8 to ATTACH_DEVICE_FS
- These options are relevant:
- Drive #. options / Read only access
- Drive #. options / File system directory...
- Drive #. options / Convert P00 file names
- Drive #. options / Create P00 files on save
- Drive #. options / Hide non-P00 files
- Otherwise...
- Drive #. device type = Raw device access -> use a real host OS floppy drive
- sets resource FileSystemDevice8 to ATTACH_DEVICE_RAW
- These options are relevant:
- RAW block device name...
- Otherwise...
- Drive #. device type = Real device access -> access device via OpenCBM
- sets resource FileSystemDevice8 to ATTACH_DEVICE_REAL
- These options are relevant:
- Drive #. options / Enable IEC device
- It sets resource IECDevice8
- Having these 2 things for IEC devices seems unneeded?
- What happens if one of the options is selected but not the other?
