[Barry Nelson]

Here is the information for type "typ" and density "dns".

TYP
specifies the device type (all types). 
Bit 0 
0 = 5-inch floppy diskette 
Bit 5 
0 = Non-Color Computer format 
1 = Color Computer format 
Bit 6 
0 = Standard NitrOS-9 format 
1 = Non-standard format 
Bit 7 
0 = Floppy diskette 
1 = Hard disk 
DNS
specifies the density capabilities (floppy diskette only). 
Bit 0 
0 = Single-bit density (FM) 
1 = Double-bit density (MFM) 
Bit 1 
0 = Single-track density (5-inch, 48 tracks per inch) 
1 = Double-track density (5-inch, 96 tracks per inch)
