Well you gonna need the SW for it ...... :-o
First I would advice searchin the HD for anything that looks like a PC (the icon
for the SW should stick out, just to long since I used the 2088 to remeber what it
looked). You may also look for anything mentioning "Janus".
Once you found it, just start it, and it should atleast open a 640x200 (CGA) window
on your WB, even if nothing is configured (assuming you don't have any GFX-card
in the ISA-slots that is). This should give you a standard PC-BIOS, and try to boot
from floppy (maybe even from a (hidden) hardfile/partition on the Amiga-HD.
If you can't find any SW, google for "Janus", or try
here ....
