Attached are the two iPXE scripts I use to load/install FreeDOS onto an
iSCSI target/volume. As you can see, they still contain a bit of
commented variations, but that is mostly because I started with this
experiment before sanhook existed, and sanbooting ISOs from HTTP wasn't
possible. Now it's mostly a matter of sanhooking the install volume as
0x80 and fdfullcd.iso as 0x81 and you're good to go.

fdfullcd.iso you can get from the FreeDOS website.

I use a Nexenta/Solaris COMSTAR iSCSI target, but AFAIK it should work
with any iSCSI target that works reliably with iPXE.

I have not tried to enable any kind of networking in my FreeDOS yet, but
from what I understand, there is supposed to be a network driver
available that is able to use the underlying UNDI.

Don't forget the "dhcp" command at start, I usually don't have it in
there, as I run all of my scripts through pxe-dispatcher,
https://github.com/robinsmidsrod/pxe-dispatcher.

If you use COMSTAR you might also be interested in this,
https://github.com/robinsmidsrod/comstar-soho-helper, to simplify
creation of iSCSI targets in a home environment.
