I am trying to boot PC-BSD 9.1 by iso loopbacking

[Lorenzo Grifi]

I wish I could know
what version of grub is
the one with drivemap --mem.
I think that with chainloading
PC-BSD will not give error
such as boot-drive is missing.
I saw that drivemap --mem$isofile
is even possible at last.
This is more or less
the try that I made:



        loopback hd1 (hd0,1)/boot-isos/PCBSD9.1-x86-DVD.iso
        drivemap -s (hd0) (hd1)
        chainload (hd0)+1



But it does not work
because "drivemap -s" doesn't support loopback.
So do you know-about "drivemap --mem"?
