Use the BB1 rom update. Check the devs folder for a slightly smaller version of Amiga OS Rom update renamed -BB1 and use it instead. The BB2 update has issues with some hardware configurations and is not *ABSOLUTELY* necessary. I believe there's even a disclaimer before you install the thing about such incompatibilities. For example, I have an MBX1230 accelerator that gives a purple screen as soon as the bb2 rom update is loaded if any ram's installed. Doesn't seem to be anything I can do about it on that machine but roll back.
Also, check into the developer version of whdload. You can enter some global variables that you may want to tinker with. Maybe you'll get more mileage out of those and be able to keep the rom update.
