Subject: Re: Boot from ISO image: what "root" device?
To: Mark Glassberg <

sorry, but this solution does not seems to be useful.. (i tried it with no results)
an iso image is not a initrd.gz file!
for what i've learned by now, the right way should be the "loopback" command but i cant find any way to use it properly
the only way i can get the sintax of this program commands seems to be reverse engineering by the source code...
:-(
any suggestion?

I'm a newbie at this. From what little I've read and tried, however, it seems
to me that the isofrom boot prompt only works after the iso has booted. I can
offer no guaranty but, if you have enough ram, try booting the iso image as the
initrd.
Good luck,
Mark
