Re:HowTo make bootable file image from /dev/hda1

Hello,

<Has anybody made a successful boot image from a fat16
<partition for use with dosemu 1.99
<
<I have the partition mounted as /dosc but that drive
<is going away, so need to virtualize to a file image.
<
<Tried
 <dd if=/dev/hda1 of=/hdimage etc...
 <mkfatimage16 -k32768 -f hdimage -b /dosc /dosc
<
<tried dd of the mbr to a separate file in combination
<with the above and none work???

I had the same idea and it seems it does not work for the dd-command.
What work is following:

1. Create a hda image with 
dd if=/dev/hda2 of=hda2.img 
(my DOS is on hda2).
Than I have created a mount point /mnt/dosimage (with mkdir)
After this I have mounted the image as loop device with 
 mount /LIBDIR/hda2.img  /mnt/dosimage -t msdos -o loop=/dev/loop0
Now it's possible to lredir the image on the /mnt/dosimage directory (in the 
autoexec.bat) and  use the programs in this drive, but unfortunately, I had 
no success to start this image.

By the way, but not helpfull for you, it is possible to boot  from a bootable 
floppy image created with 
dd if=/dev/fd0 of=floppy.img
Then in dosemu.conf 
$_vbootfloppy=floppy.img and it works at least if the floppy was 1,44 MB. With 
720 kB floppys I hadn't success.
