68060 shows up as 68040

[bytebandit]

I recently acquired an apollo 1260 and when I use sysinfo or the cpuinfo command it shows up as a 68040. The cpu jumper is set to 060 but the clk jumper is set to 040. If I change the clk jumper to 060 the amiga won't boot. Can anyone tell me why this is? I thought perhaps it was to do with the speed of the memory? Still strange it shows up as 040 though? Does anyone have any ideas?

BTW, The benchmarks on SysInfo 3.24 are: Mips 38.88, MFlops 27.89.

thnx.
