The only clue I have is that when booting up, before WB loads, a message flashes saying something like 'could not create graphics board context'.


I've had all sorts of trouble (mostly me being a dumb user) with my A2000/PII machine.

However, the above is one problem that DID go away once I upgraded my PSU to a 300w ATX unit. :)

Before doing that, I replaced with a different A2000 PSU & the problem only sometimes presented itself, but once the much better ATX unit was installed....never again :D

Hang on a second!

How much memory does your '060 have set to autoconfig? (Check your jumper settings)

I know others have touched on this, but for example, if you have more than 6mb set to autoconfig on any other devices, your PII won't work...ever.

Obviously the figures vary depending on graphics card memory, so a graphics card with 4mb on board can only allow another 4mb of autoconfig memory from another device/devices, like processor card, HDD controller, etc.

This would be about the ONLY thing I figured out myself with regards to the Picasso...LOL :D

know where I can get one of these power supplies (anything on eBay is the stock PS's).

Use a PC ATX unit like I did. Cheap & easy :)

Check Stedy's guide for a how-to: http://www.ianstedman.co.uk/Amiga/amiga_hacks/Amiga_Power_supplies/body_amiga_power_supplies.html#Fitting_a_new_PSU_to_an_A2000

Make sure to test the PSU with a multimeter though. First one I tried didn't work & I freaked about killing the A2000. The PSU was just dead! LOL :D

Yep, the memory on the accelerator has nothing to do with ZorroII memory space.


Really? When autoconfig jumpers are set on my PPS '040, it seems to allocate to Z2? Autoconfig none & software controls the lot.

I took a look but couldn't make much sense, other than changing the jumper on the motherboard - I'm guessing I'd be doing wire stripping? If I don't solder the wires then wouldn't I need some kind of wiring connector???


"A new connector is an TBD 14 way connector."

If you are unable/unwilling to do the job yourself, you can always buy a good quality adaptor cable:
