Fresh install of WB 3.1 on 4000D limited to 16 colors?

Greetings fellow Amigans -

I'm restoring a A4000D and running into a strange problem. The ScreenMode tool will not let me choose a color pallet greater than 16 in the PAL High-Res mode. On my A1200, I can go all the way to 256. and I copied the PAL monitor defintion from there to this machine to no effect. The system is a Rev B motherboard, A3640 rev 3.1, Colanto 3.X ROMs, and I used the Colanto Workbench 3.1 ADF images from Amiga Forever 7 via a GOTEK running FlashFloppy for the install. I have also installed BetterWB 3.1. This is the same process I used for my A1200 (but those Colanto WB disks may have been from Amiga Forever 6) and that worked. Any ideas of what I have done wrong/need to correct?

If you are using a standard Workbench the problem could be Hardware

Maybe wrong ROM's. Type "SetPatch" in a shell and see if it activates AGA or is already activated.

If ROM is correct: damage caused by leaking battery can cause SetPatch not to detect AGA (sometimes without causing any other problems).

Thanks for the info everyone, I'll be sure to try all of these as soon as I'm in front of the machine again at the end of the week. I wasn't expecting responses so soon!

Thanks again for the input everyone. SetPatch does state that AGA was already activated. It's possible the problem was my Workbench disks were read only during install, and I have found that can cause issues. I'll look into a complete re-install and see what that does. Thanks again for all the info thus far!

You should *never* write-enable your Workbench disks. There is nothing which needs to write to the disks during installation. If it tries to write to the Install disk, then you chose the wrong destination.

HDToolbox might want to save its drive definitions to the disk it was run from. Just drag it to RAM disk and run it from there. Or change "drive definitions" to "ram:drive definitions" before you leave the "change drive type" screen.
