Command: program 27C400 (512KB)
Slot? 0-3
Size? 1=128KB? 2=256KB? 5=512KB
Byte swap? y/n
slot 0, filesize 262144, byteswap 1
Erase, done
Address=000000,07ffff
Send binary

Took 5.267s

OK

On Amigas ROM images used for emulators will need byte swapping.

4. Use

Power on the A500 and it will boot to Kickstart v1.3 you just programmed.

Press and hold Control+Amiga+Amiga for two seconds & release. System will restart to Kickstart v3.1

Press and hold Control+Amiga+Amiga for three seconds & release. System will restart to Kickstart v1.3 again.

>2.5s	Switch to ROM slot 0 (zero) Tap reset to increment ROM number e.g. 3s + tap + tap => slot 2
>5s	Cancel switch (stay on same ROM)

Autosave will save ROM slot/bank for next boot after 10s.
