AMIGA 500 - 3x RESET BOOT DRIVE SELECTOR (SWITCHLESS BOOTER)


One of these files can be progammed into pic16f628 or pic16f628a

"Primary internal" boots from internal drive when you turn on your Amiga.

"Primary external" boots from external drive when you turn on your Amiga.

After 3 resets Df:0 <> Df:1 drives switches. (Reset Keys: CTRL and the two Amiga keys together)  

Instead of 3 resets, you can press comtinuolusly reset buttons for about 4 second.

When you are booting from external drive, you need to Turn On internal drive (DF:1) from software, like "X-COPY - Drives On" command. This is not a bug, it happens the same when you are using switched old style boot drive selector.

Thank you.
