ok guys,
here's the thing that method worked but it apparently was not the method I'm suppose to be using. Apparently you have to make the image look like a floppy disk. The method I'm suppose to be using is this:
and as is expected, it doesn't work
I get an error message saying, "loop0 was not found in /etc/ftsab or in /etc/mtab", when I try executing the forth command.
hey, i just found this forum...how cool.
question:
does anybody know code or know where i can get the code to get a certain image URL from user? say user input URL from shell prompt when run the program. What is the code to take that URL open internet and download the image.
thanks alot. (2 Replies)
Hi,
I have a windows emulator that I am wanting to try out, but my Windows 3.1 files are split up over 6 .DSK images, and I need to convert them to an .IMG that I can actually mount on my system (so that the emulator can see it).
Is there a way to do this?
thanks.

LOSETUP(8) System Administration LOSETUP(8)NAME
losetup - set up and control loop devices
SYNOPSIS
Get info:
losetup loopdev
losetup -l [-a]
losetup -j file [-o offset]
Delete loop:
losetup -d loopdev...
Delete all used loop devices:
losetup -D
Print name of first unused loop device:
losetup -f
Setup loop device:
losetup [-o offset] [--sizelimit size]
[-p pfd] [-rP] {-f[--show]|loopdev} file
Resize loop device:
losetup -c loopdev
DESCRIPTION
losetup is used to associate loop devices with regular files or block devices, to detach loop devices and to query the status of a loop
device. If only the loopdev argument is given, the status of the corresponding loop device is shown.
Note that the old output format (e.g. losetup -a) with comma delimited strings is deprecated in favour of the --list output format (e.g.
losetup -a -l).
OPTIONS
+The size and offset arguments may be followed by the multiplicative +suffixes KiB=1024, MiB=1024*1024, and so on for GiB, TiB, PiB, EiB,
ZiB and YiB +(the "iB" is optional, e.g. "K" has the same meaning as "KiB") or the suffixes +KB=1000, MB=1000*1000, and so on for GB, TB,
PB, EB, ZB and YB.
-a, --all
show status of all loop devices. Note that not all information are accessible for non-root users. See also --list. The old output
format (as printed without --list) is deprecated.
-c, --set-capacity loopdev
force loop driver to reread size of the file associated with the specified loop device
-d, --detach loopdev...
detach the file or device associated with the specified loop device(s)
-D, --detach-all
detach all associated loop devices
-f, --find
find the first unused loop device. If a file argument is present, use this device. Otherwise, print its name
-h, --help
print help
-j, --associated file
show status of all loop devices associated with given file
-l, --list
if a loop device or the -a option is specified, print default columns for either the specified loop device or all loop devices,
default is to print info about all devices.
-o, --offset offset
the data start is moved offset bytes into the specified file or device
-O, --output columns
specify which columns are to be printed for the --list output
--sizelimit size
the data end is set to no more than size bytes after the data start
-P, --partscan
force kernel to scan partition table on newly created loop device
-r, --read-only
setup read-only loop device
--show print device name if the -f option and a file argument are present.
-v, --verbose
verbose mode
ENCRYPTION
Cryptoloop is no longer supported in favor of dm-crypt. For more details see cryptsetup(8).
RETURN VALUE
losetup returns 0 on success, nonzero on failure. When losetup displays the status of a loop device, it returns 1 if the device is not con-
figured and 2 if an error occurred which prevented from determining the status of the device.
FILES
/dev/loop[0..N]
loop block devices
/dev/loop-cotrol
loop control device
EXAMPLE
The following commands can be used as an example of using the loop device.
# dd if=/dev/zero of=~/file.img bs=1MiB count=10
# losetup --find --show ~/file.img
/dev/loop0
# mkfs -t ext2 /dev/loop0
# mount /dev/loop0 /mnt
...
# umount /dev/loop0
# losetup --detach /dev/loop0
