I am fairly sure that DOS software to write CDs and the even earlier

challenge.

Adaptec EasySCSI will provide a set of ASPI drivers...

Getting the network card to behave on the embedded box and then using
network shares might be the least difficult way out. The external PC
can run a modern OS that handles the backup process.

One of the old TCP/IP application stacks for DOS with FTP would probably
be an option. (assuming once loaded there is enough ram left to run the
CNC software ;-) Ah the joys of DOS emm/xms/umb management.

This is what makes virtualisation the winner. If ever there was a case
of a "Solution looking for a problem to solve.", virtualisation is that
"Solution" and Andrew's problem is that very problem virtualisation was
looking to solve. :-)

The only slight gottcha would be if the DOS code needs to bang the
hardware in a particularly unorthodox way, or the code timing is
particularly critical.


Oracle's VirtualBox can be installed on either windows or unix hosts
(free for personal use - I suspect Andrew might have to pay a licence fee
in this commercial usage case though) and although it can benefit from
Intel's VT-x processor feature, it isn't reliant upon its presence which
might be an important consideration in this case.

It also got Day of the Tentacle running nicely on a modern PC ;-)
