Title: Amiga 2630: how do I engage the FPU on startup?
Post by: barney on July 17, 2009, 06:26:41 AM

I remember being able to do this in the past, but I have forgotton how.  Does anybody remember how to engage the Amiga 2630 Accelerator FPU on Bootup?  I have it in stalled in my Amiga 2000.  Thanks.

I thought it was always ON and all you had to do was run any program that was written to take advantage of it.

The FPU is always on, unless you switch back to 68000 mode (hold down right mouse button on startup for the menu).

Do you mean the CPU command?

I thought their was a specific file you had to put somewhere to make it start on boot up.  I could be wrong but when I run sysinfo, it leads me to believe that the FPU isn't on or functioning.  Note: I am aware of the 6800/68030 option on start up.  That isn't what I was referring to.  Thanks.

Aren't you confusing FPU with MMU? The MMU is the only one that can have the "Not in use" state in SysInfo.

If it is not showing up in Sysinfo, it could be dead.  Not "ON" is not part of the equation as far as I know.

Run ShowConfig from the Tools directory. What does it say?
