English Amiga Board - View Single Post - Auto-setting chipset to "original" on AGA startup

If your code is running on the bootblock then AGA is already disabled (more precisely it has not been enabled yet).
Your target doesn't run SetPatch, does it ? Does it have a startup-sequence at all anyway ?
And have you checked that it works fine if setting the chipset in the bootmenu ?

Perhaps you need to add this line to your startup, especially if it kills the OS :

Code:

 clr.w $dff1fc
