Hi, I've got a problem with bought A4000 desktop and I expect to find someone competent here which would help me to fix it.
OK, so the problem is that system doesn't recognize AGA chipset. Here are some facts:
1. In Early Startup Control there is no option called "Best Available". Only "Original" and "Enhanced".
2. When the system boots I can only choose OCS modes e.g. Lores 32 colors and Hires 16 colors.
3. Interesting fact: when the system boots with "Cache Disabled" in Boot Menu the computer starts with distorted graphics but the ECS modes are available now.
4. Replacing ROMs didn't solve the problem.
Is there someone which can guess what's faulty in this A4000? Is it possible that it's something with processor board?
Silly question, but are you sure your Workbench installation is okay? Workbench 3.0 or above is required for AGA screen modes. So for instance, 2.1 Workbench is not capable of AGA screen modes even with an AGA capable Setpatch such as the one that came with 3.0/3.1.
If you haven't already checked, do a COLD boot from a 3.0 or 3.1 Workbench floppy and load the Screenmode prefs program from the Extras3.0/3.1 disk and verify the problem. You've more than likely already done this, but just wanted to double check. :rolleyes:
