3640 and WarpEngine in 3000

[wheels]

I've rencently tried a 3640 rev. 3.1 and a WarpEngine in my 3000 rev 9 with no luck. I get no boot screen or colors just black. No disk access or click.

The 3000 works fine with native processor. The board has no battery and 8 meg of Zips 2 meg chip.

Any ideas? I've run out of variables.

I used to use the A3640v3.1 in my A3000.  I think I had to do the INT hack that you'll find on Aminet (you have to solder a small wire from a pin on the accelerator slot to another chip).  This made my machine work even with Ramsey4/DMAC2 combo though I did eventually upgrade to Rev 11 Superbuster for better Zorro III (though I've read it's necessary sometimes to upgrade to Ramsey7/Dmac4 for the 3640 to work).  Before you spend any money though, make sure first off that the jumpers on the motherboard are set properly to use the external clock on the A3640.  There is an Amigaguide document on Aminet that explains all this I believe.  You might also consider cutting a square hole in the drive tray on the right side of the computer and placing a fan on the A3640 heatsink because it runs hot and you wouldn't want to melt a trace in you A3000.

Read this first before cutting and hacking. Using the A3640 in an A3000

Then find a Warp Engine for the A3000.  This unit fits a bit better in the 3000 but you still might have to drill/cut the chassis for a fan.  
There's also a slightly different model for the A4000.

Hope this helps.

Thanks for the notes.

Any other ideas? I have the Int wire on and the case open so no worries about heat. This machine does not boot at all. No sign of any activity. Could both of the boards be bad? Its possible.

I have all the jumpers set as well.

Hello,

I'm really rusty, but a couple more ideas.  Check the Rom revision of the machine.  I don't think a Softboot Machine will work with an accelerator.  You may need 2.04 or higher roms.

Also you may need static column ram in at least the first bank ?  Just some ideas.  Also check jumpers are set for an external clock source.

Have you installed the 68040.library?

I would assume you have the backplane daughterboard installed while testing this, right?  My 3000 won't boot without it.

I just installed a vers. 3.1 A3640 into my A3000D that worked fine in my A4000D. I set the recommended jumpers per the above link and went to boot. I got the guru meditation screen because the SCSI drives installed softkicked 3.1 ROMS. So I removed the HDD and booted into WB2.1 via DF0 since this A3000D has 2.04 ROMS. All checked well with the 68040 processor recognition in SysInfo, but I noticed the FPU and the MMU were disabled. The speed check was marginally slower then the stated speed for a 040 A4000, but I was sure the disabled FPU and MMU caused that. Does anyone know how Enable those features on the A3640? I have checked and the chip is in fact a 68040RC25.

Hi,

the WarpEngine should work with Kickstart-ROMs 3.1.
The clockjumpers should be set like for the onboard 030.
So you can switch between 040 and 030.
It's the only board I know to do this for the A3000.  :-o
If Autoboot is anabled, the WarpEngine waits a long time for scsi devices.
If you need the manual look at http://www.amiga-hardware.com .

I'm assuming you do have the jumper set for external
CPU. You will get what you are describing if not all
the jumpers are set correctly.
I had this same problem on my A3k when I first installed
a 3640 card. I later moved up to the WarpEnging 040 @40mhz.
I really like the WarpEngine.
Also if you are sure the jumpers are right, you can try
spraying some contact cleaner in the card slot.
I had this problem on my A2000, the slot was dirty and
sometimes the card would work and sometimes it wouldn't.
Assuming the card is good then if the machine runs
without the card it should run with it (with jumpers
set correctly).
