	Without getting into too much analysis... 4 chips (assuming 256k =
1Mb). 16 / 4 = 4Mb. 24 / 4 = 6Mb. It is more likely the chips are 128k
or 64k chips. This would make the numbers sound better. Check the card
for jumpers. Your manual should tell you what to do. 

	As to not booting into Prodos... If it is ProDOS 8 then chances are it
is a problem with your floppy...
