automate creation of hard disk image

[David N. Welton]

Hi, I have a disk image I am creating in a file, hd.img.

I've been attempting, so far without success, to automate the 
installation of grub to this disk.  It's not a complex setup - just a HD 
image for use with bochs (and eventually on the target system), but 
things don't seem to be working.  Having looked around with google, I 
found commands such as device (hd0) /home/davidw/hd.img that were 
supposed to do the mapping, but it gets the geometry all wrong.  I tried 
correcting it with geometry, but that didn't help either.

Any suggestions would be most welcome.

Thankyou,
Dave
