Thanks, got it
I have a GVP running now... What ROM version do I need in a GVP Impact-Series-II A500-HD+? I have no problem with autobooting a 980MB partition on a 2GB card in A500-68040 mode, but the speed is slow. (Less than half than the speed if I switch into 68000 mode!! See the Speed Comparison thread here.)
Or should I burn some version of Binddrivers?
