OK, so I'm a novice so I'll recap what I did.  Starting with FreeDOS
boot floppy and copied debug.com and debug98.com to the FreeDOS
directory on it.  Booted from the floppy, selected option 2 (safe=20
mode, no drivers loaded).  Typed debug and then:

=2D A
2890:0100 mov AX, E801
2890:0103 int 15
2890:0105 int 3
2890:0106
=2D t
AX=3DE801 BX=3D0000 CX=3D0000 DX=3D0000 SP=3DFFFE BP=3D0000 SI=3D0000 DI=3D=
0000
DS=3D2890 ES=3D2890 SS=3D2890 CS=3D2890 IP=3D0103 NV UP DI PL NZ NA PO NC
2890:0103 CD15      INT      15
=2D

Does that look correct ?  I presume it was just <enter> to leave
the 'A' mode to go back to the command mode ?

cheers,
Chris
