Hi thank's for the reply's that's what i thought the A500+ and the A600 are very similar in memory it's like i said i can transfer adf's two the A500+ but not the A600 unless the A600 users more memory to boot the workbench disk i really dont know,i just thought there was something wrong with the A600's memory
No, you're just using too much of it already. If you're booting the two amiga's off the same bootdisk then the difference could be due to extra hardware in the 600 using more memory.
Either the IDE or the PCMCIA slot drivers could be using ram, even though they haven't got anything plugged into them. Also having extra floppy disk drives uses more ram.
