It's for the Setpatch command in sys:s/startup-sequence.
Look for the line
SetPatch SKIPROMUPDATES "scsi.device" QUIET
and change it to
SetPatch NOCACHE SKIPROMUPDATES "scsi.device" QUIET
But I don't think this is really what you want. Try booting you Amiga with the "2" key held down. This disables the 060 entirely. (Unless like me, it doesn't work, probably due to my keyboard adaptor and Windows Keyboard)
