RE: Writing multiple CD volumes for the AS/400? -- MIDRANGE-L

Brad,

I just inserted a CD/RW into our new 820 box.  It currently has
about 200MB of PC stuff on it.  Using OPSNAV I was able to access
the disc via OPT01.

Unfortunately, the only thing visible was Adaptec's UDF Reader
directory with two files (udfrinst.exe and autorun.inf) :-(
