Hi everybody-

I am attempting to experiment with DOSFS from Lewin Edwards. The
chosen platform for my experiements is Windows. I'm running into a
stumbling block that I'm sure has an easy solution:

When compiling for testing using the HOSTVER macro defined, how does
one create the initial image file with which the test program uses for
mass storage? There is a small hint that a utility exists under
Windows that will create that file but that's the extent of the
suggestion.

Here's a cut from the readme file:

"The demo suite includes an emulation
module that reads/writes a disk image file (#define HOSTVER pulls
in hostemu.h which wraps the prototypes for these functions).
There are various tools for UNIX, DOS, Windows et al, to create
images from storage media; my preferred utility is dd."

Mr Edwards is clearly anti-MS so I have some doubt a the Windows
question directed to him will invite a happy response. Can anyone
answer my question?

Thanks, JJS

It might not be possible to get a "real" image of a card within
Windows, depending on what device you are using to read the card. You
really want something that will give you int 13h (physical) access, so
you can get to the MBR. Drivers for many USB readers only give you int
25/26h access (logical) so you will only be able to dump a "big floppy"
image. While such an image WILL work with DOSFS (simply give the
starting sector as 0 when you mount it, and don't parse the MBR since
it isn't there), it's not a realistic view at what your appliance is
going to see. If you have a PCMCIA adapter for your flash media, that
will most likely allow you to read the card properly.

You can use something like an old copy of Norton Disk Edit. You can
also use the program AXE to read the card

I use 'dd' in Win32 (mostly Win2k); just use a 'cygwin1.dll' to match
the 'dd.exe' that was compiled for it or use a native 'dd.exe' of
which there are many available out there. You will need to use
device names like /dev/fd0 for the A: drive and //./PhysicalDrive0
for the first hard drive on the first bus (may be scsi or ide or sata
or whatever depending on your configuration), and so on.

You ought to be able to build DOSFS under cygwin as well. Please
also deja-google this newgroup for my other posts regarding Lewin's
DOSFS in re patches and bugs.

Yes, I'm sure.

Just in case you missed it, I was quoting the OP. My one contribution was
the smiley - I did indeed have a chuckle at the OP's wording .
