I feel bad about apparently, opening the issue of patents and proprietary information in my response to Niklas on this mailing list. I don't see that Niklas and this group of interested individuals should be discouraged from pursuing the goal of producing free and open-source software.
You shouldn't feel bad about that Ron, I think it's great that the issue was brought up. Atleast I haven't been discouraged at all, rather gained some important knowledge. Such as that a) I should _never_ sign any NDA and that b) it might be alright to disassemble other BIOSs to gain knowledge on how to perform a certain task, as long as you never take any code from the disassembled BIOS.
(However I don't have the intention to disassemble any BIOS; it just seems safer to never have touched any commercial BIOS at all.)
So far, I am not aware of any successful legal claim that was taken against an open-source developer, who originated their code on their own, without copying other people's code.
Neither have I, and I surely wouldn't want to the first one either! =)
Many times you may NOT want to reinvent the wheel. Sometimes you HAVE TO. Maybe we should look at developing BIOS specifications of our own, avoiding legacy design problems that plague most existing software and reaching beyond just compatibility with current commercial BIOS.
I can assure you that GNUBIOS will be anything _but_ a IBM-PC compatible, legacy BIOS. GNUBIOS will be built in three stages. In the first stage, it will be a 32-bit protectedmode BIOS able to boot Linux and other OSs through the Multiboot standard (no real fancy features though). In the second stage a BIOS Runtime Interface will be added and the possible to boot from more devices etc. In the last stage, a full Open Firmware implementation will be made (Open Boot standard, IEEE 1275). Most of the BIOS will be rewritten to Forth in this stage (everything but the chipset setup so that the FCode interpreter can run).
For those that doesn't immidiately see all the cool benefits of Open Firmware; wait and see! It will rock immensely.
