... E and L jumpers have to be set.

Maybe if they are not, the Warp tests all memory for errors?

So with the auto boot switched off does it still take 8 minutes to show the Rom screen?

Have you tried another CPU board?

If you're in the UK I can lend you a 030 CPU board for testing

Using another cpu board was discussed earlier in the thread. That is the next logical step . Thanks for the offer but I am in Michigan.

Thanks for the picture,
I see nothing wrong with the jumpers other than "D" should be removed to have no wait state ram(if its 60ns ram,remove it).
this would no affect anything.

Are the Amiga motherboard jumpers set to EXT?

even if boot delays were set and luns scanning on it still wouldnt take that much time.
I am using the warpengine in a A4000 with scsi card reader and full device and lun scans and it is still pretty quick.

Its a perplexing problem you have there.

On your photo you appear to have the SCSI cable inserted mid run of the cable.

Is anything fitted on each end of the cable currently?

I show here the scsi ribbon set up, connecting on card, CD and back plate scsi connector.
I also try booting with cable completely disconnected.

Also show jumper connection on MB for Mechy.

If you've got a SCSI device on each end of the cable you need to remove the termination on the WarpEngine.

I believe I removed them now. Are they the three pins aligned in a row next to scsi cable connection?

This is my 3rd attempt at replying to this lol

As far as I can see they should be the ones.

Have you got a copy of the manual?

Yes checked manual. Thats it. No change.
I’m thinking scsi problems aren’t it.
This hobby is fun.

It certainly is with my 4000D as well.

It's been it bits for a year and I'm now just putting it back together after sorting out a few things.

I've installed 3.2 but it seems very slow so I'm going to try it with 3.9 again.

Everything looks ok settings wise.
Here is the warp engine manual: http://amiga.resource.cx/manual/WarpEngine.pdf

Someone mentioned you have the middle of the cable connected to the scsi card? this is not recommended,but since you had scsi completely disconnected with no change its likely not the problem.
