Managing Images¶
For cbm-shell
to be able to access the contents of an image it
must be associated with a drive number. That is done by attaching the
image:
(cbm) attach mydisk.d64
Attached mydisk.d64 to 0
Up to ten images may be attached at any one time.
To prevent modifications to an image it may be attached read-only
(cbm) attach --read-only mydisk.d64
When an image is no longer required it may be detached:
(cbm) detach 0
Detached D64Image(mydisk.d64)
The list of currently attached images can be displayed using the
images
command:
(cbm) images
0 RW D64Image(mydisk.d64)
Creating New Images¶
New disk images should be created using the format
command:
(cbm) format EXAMPLE E1 example.d64
Creating empty disk image as example.d64, EXAMPLE:E1, type d64
The type of image created can be specified using the --type
argument
(cbm) format --type d81 EXAMPLE E2 example.d81
Creating empty disk image as example.d81, EXAMPLE:E2, type d81
A new tape image can be created by attaching a non-existent file.
Subdirectories¶
Images from 1581 drives (.d81) may contain nested filesystems called subdirectories. These may be attached after the parent image has been attached by using the drive number and entry name:
(cbm) attach 0:SUBDIR
Attached ImagePath(0:b'SUBDIR') to 1
The subdirectory can then be addressed in the same way as an image, including attaching any nested subdirectories.
