Blizzard 030 Mk4....show me your 68882!

[NovaCoder]

I'm going crazy (maybe), I've now got a 68882 FPU installed in my Blizzard 030 Mk4 for my 1200.  Although SysInfo reports that the FPU is installed no 'FPU intensive' games or demos that I've tried so far seem to be able to 'see' it :-?  

I've tried TFX and Alien Breed 3D along with a couple of AGA demos which reported that the FPU not present?

I thought it was just a plug-and-play type thing, anyone got any ideas?

Do you have all the appropriate "setcpu" type commands in your startup sequence to enable all features of your accelerator? Im not familliar with the "blizzard" line, but it seems to be quite common with other brands of accelerators to have commands that turn on & off features that you do/don't want. These commands are usually executed very early in the s:startup-sequence...

Nope I've got nothing in my startup-sequence...maybe this is my problem?

Blizzard has autoconfig(TM), it doesn't require "set" command here.

Does C:CPU command see the FPU? If so, then it's working fine. However, don't expect any speed boost, most of the time the FPU is in fact slower than the fixed point math done via CPU.

Thanks I'll the 'C:CPU' command tonight.  It's a bit strange because SysInfo can see the FPU but the AGA demo said 'FPU: None'?

 But did you perform the speed test? If it returns a value in MFLOPS, your FPU should be ok. Double check it with SysSpeed and AIBB.

What does it return the reading as if you don't have an FPU?

Are you sure that AB3D utilizes the FPU?

No, not sure about AB3D (just a guess) but I know that TFX does as it uses a seperate exe.  I'll try that FPU demo that was suggest in this thread and see if it runs.

Thanks for all your help guys  :-D
