hmmm, nope, not really... the basic issue is that the amiga has auto config'd everything before you've even got to the early startup screen... your best option is to manually set the hawk to tell the amiga it is a 4Mb board. with the following jumper configs (stolen from Zetro's post on a similar subject on EAB)
to configure the board for 8MB
LK1 = open, close, close
LK2 = close, close, open
LK3 = open, close, close
to configure the board for 4MB
LK1 = close, close, open
LK2 = close, close, open
LK3 = open, close, close
to configure the board for 2MB
LK1 = open, close, close
LK2 = open, close, close
LK3 = close, close, open
to configure the board for 1MB
LK1 = close, close, open
LK2 = open, close, close
LK3 = close, close, open
i guess where it says "open" is where you want to put a jumper. and hopefully, it'll ignore the upper 4Mb where the pcmcia lives.
hope this helps :-)
