How to also Mount hdimage file at /
I made a mkfatimage16 file which works fine with
dosemu. I have a need to let Windows (samba) to
mount the same via the network.
I can use mtools to see the file as drive m:
but I need to mount it under /dosc so that windows can also write to it.
When the hdimage was a real dos partition mounted on /dosc, I could use dosemu and windows would also see myhost://dosc
Does anyone know how I can mount the hdimage (now a file) also as /dosc. Also tried using the loop device: mount filname /mnt -t msdos -o loop, but it complains about the file's format.
Thanks

By looking at hdimage file created by mkfatimage16m I noticed that the boot sector was at offset 0x2280, rather than at 0, if it was a device /dev/hda1. So I truncated the hdimage file by cutting off the first 8832 bytes and redid the mount command above and it worked!
However, dosemu will not work if $_hdimage is set to the truncated image. So I need a way to specify the file starting at offset 0x2280, while leaving it intact... But I do not know how to specify a file starting at a byte offset...

According to "man losetup", maybe "losetup -o" but I've never tried it myself.

Great discovery. It did work!
----------------------------------------------------------------
losetup -d /dev/loop3 <detach and clear loop3>
losetup -o 8832 /dev/loop3 /hdimage-32MB.mdos <attach to loop3 @off=8832>
mount /dev/loop3 /dosc -t msdos <voila!, done deal!>
----------------------------------------------------------------
Then export the drive's /dosc with smb.conf and MS-Access can read/write to a file that dosemu is using inside of a partition inside a Linux file in a networked embedded linux appliance.
Great capability for dosemu, since starting with Windows 2K/sp4 and also to a lesser extent XP/sp1 Dos mapped drives are no longer allowed in the Windows network. Samba2 and 3 still work fine!
Gracias,
