Well I could write this tedious story of all my considerations :-) But then everybody would go for the 'kill'-button. My reasons for using the AHA kernels is that they worked for me. In contrast to the BT kernels. AND I can not find any info in the release notes of GAMMA which tell me that the BT-kernels work with a 445S. Which is a very troubled card :-( I do admit it is in the same row of BusLogic cards, and that could suggest something. :-) If I switch the 2-10 switch the damnedd board doesn't even passes it's bios boot. :-( Maybe I shouldn't touch the switch :-) => >Whether or not the 3.37 => >eprom fixes the >16MB DMA problem is, however, still an open question => >for ANY of the operating systems.

They even faxed to Taiwan on this topic. Is there any way of finding out if problems are really due to this feature?
