How to create particular .img format files using disk-analyse?

[z80micro-mc]

FlashFloppy uses an img.cfg configuration file to define the format of a .img disk file.

How do I get disk-analyse to create such image files?

I want to convert a .IMD file into a .IMG file for use on FlashFloppy.

FlashFloppy img-cfg record of interest:

3.5/ 5.25" 2x1sDD 166+166kb

[RM-SEQ-2x1SDD::363520]
cyls = 40
heads = 2
gap = auto
rpm = 300
file-layout = sequential
tracks = 0
h = 0
secs = 16
bps = 128
mode = fm
rate = 125
id = 1
tracks = 1-39
h = 0
secs = 9
bps = 512
mode = mfm
rate = 250
id = 1

This is a 40Track mixed density (FM 16 x 128 byte sectors on track0, MFM 9x 512 byte sectors tracks 1-39)

Thanks

Peter
