Sorry! I was rushed and I forgot some things!

I'm CCing the list on this..

Distribution: RedHat 7.3
DosEMU Ver (as reported by RPM) 1.1.1-3
DOS ver: Caldera Dr-Dos 7.03
Program: FastEcho 1.46 (I'd not be surprised if no one has heard of it).
EMS/XMS/DPMI define: 8192KB
CPU defined: 80586
PCI: On

Anything else that would be of value? I'll name it off if requested.
