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 :-)

A500, A600, A1200x3, A2000, A3000, A4000 & a CD32.
and probably just like the rest of you, crates full of related "treasure" for the above XD

heh, that would be cool. a "super early startup" screen, where the amiga goes "here is a list of what i found, please tick what you don't want me to use"
