### Floppy Directory
|
|
|
|
Put floppy images in this directory. Valid image formats are flat sector images
|
|
of the type created by WinImage, dd or other such utilities, typically with \*.img
|
|
or \*.ima extensions. Compressed \*.imz images are not supported.
|
|
|
|
MartyPC will adjust the floppy drive size within the capabilities of the currently
|
|
emulated machine, based on the size of the image loaded. Thus if you load a 720KB
|
|
floppy image, the drive becomes a 720KB floppy drive. There is no need to configure
|
|
this setting.
|
|
|
|
However, if emulating a IBM PC or XT, note that certain floppy sizes will not work
|
|
as the machine/BIOS does not know how to handle a disk of that size.
|
|
|
|
Floppy images must be one of these exact file sizes:
|
|
|
|
|bytes|type| |
|
|
|----|----|-------|
|
|
|163,840 | 160KB floppy, single-sided | Rare, only used by the earliest PCs.|
|
|
|184,320 | 180KB floppy, single-sided | Rare, only used by the earliest PCs.|
|
|
|327,680 | 320KB floppy, double-sided | Somewhat rare. |
|
|
|368,640 | 360KB floppy, double-sided | Extremely common. |
|
|
|737,280 | 720KB floppy, double-sided | Extremely common. |
|
|
|1,228,800 | 1.2MB floppy, double-sided | Extremely common. |
|
|
|
|
The exception is anything smaller than 163,840 bytes will be loaded as that size,
|
|
padded with 0s.
|
|
This is a convenience feature for development of boot sector software or loading
|
|
of boot sector demos and games.
