Title: Command or utility to disable an FPU?
Post by: Ral-Clan on March 01, 2011, 03:15:36 AM

Hi, with AmigaDOS's "CPU" command one has a nice convenient way to disable caches on one's CPU.

But is there a way to disable an FPU through software?  I.e. a command or a small utility that will shut of an FPU?

Thanks!

Nope.

On Blizzard boards you can, by holding down the "2" key on reset, but it's pretty useless as it also disables the CPU and the extra ram... :(

Curious though, why would you want to just shut down the FPU ???

Benchmarking perhaps?
