This is an example of a DosDriver for CD0 using the Subway & ASIMCFS Ver 3.6

/* ASIMCDFS MountList For CD0 using Subway */

Device = usbscsi.device
Unit = 0
Buffers = 192
BufMemType = 5
Mask = 0xffffffe
Flags = 0
FileSystem = L:ASIMCDFS
DosType = 0x662dabac
GlobVec = -1
Mount = 1
Reserved = 0
LowCyl = 0
HighCyl = 999
Surfaces = 1
BlocksPerTrack = 32
Priority = 10
StackSize = 5000
#

Not sure which version of ASIMCDFS you have but it should be similar to the this version unless it has been updated to allow you to use the tooltypes of the CD0.info icon file.

In which case you’d need to put the following tooltypes into the CD0.info file…

DEVICE = usbscsi.device
UNIT = 0

The above are just as an example if your going to call the device CD0 and using ver 3.6 of ASIMCDFS and using it as unit 0… 🙂
