No, they would prosecute some college student in Sweden for breaking the law. Phoenix was **VERY** careful in how they reverse-engineered IBM's BIOS. There were two teams. Team one disassembled the IBM code and wrote a detailed english-language description of what IBM did: This function when called this way does this. No code was contained in this description. Team two had **NEVER** (not once, not ever) in any way disassembled any BIOS code ever, had never seen IBM's code ever, etc. They took that english-language description and wrote their own code. Even if there were parts of the code that were exactly identical, it wouldn't have mattered, because they came up with them on their own. That's why it's called "clean room" development. The guys that have never seen the code they're trying to copy are in a clean room: free from suspicion. *That* is perfectly legal. But once having seen copyrighted code, you **cannot** write code that does the same thing without opening the possiblity of lawsuit. I'm not saying that they'd win, but there is the possibility of a lawsuit. And if **any** similarity was found (even if it were coincidental), you would lose. >> This is very true.

Even if they hadn't, they would still have been in the wrong. If I'm an engine designer for Ford and leave to start my own engine-designing company, Ford would have every right to go over my designs with a fine-tooth comb. And if something even coincidentally looked the same, I would be in big trouble. That doesn't mean that I couldn't leave Ford and start my company. Look at Lee Iacocca (sp?), or John DeLorean. But it opens the *possibility* of attacks. > Niklaus would be taking a bigger risk if he signed Intel's >NDA. Right now, he has no legal obligation to protect anyone's >secrets.

But no one could stop you >from selling cola drink (you couldn't *call* it "Coca-Cola", of >course), or posting the formula on the web. Yes they could. If I were given the text of a book from a disgruntled publishing employee, and I put it on my website, could I be prosecuted? Not until I was told of the copyright violation. But once I was told, that's it. I am open to prosecution. And, if I were found publishing a manuscript that was given to me, and it was found that the manuscript was not owned by the person who gave it to me (just as if I were given the secret Coke formula by an unauthorized person), I would be in big trouble. Ignorance of the law is no excuse: it's still illegal. So, all of the actions that you describe are quite illegal. Duplication of copyrighted material is a crime. Period. And once you've seen copyrighted material, copying that material (even if it's by rewriting it yourself from your understanding of that material) in any way opens you up to possible prosecution as well.

Re: [OpenBIOS] (was) Intel holding back information: Maybe we should move on...

As much as I hate to say it, this is probably the best way to go. This will put the OpenBIOS into a totally PC-BIOS-uncompatible track. That makes OpenBIOS just about useless to me personally in the short-term (an OS/2 and WinNT user), but it assures a path that won't get OpenBIOS in trouble with the law...

You got it. If you **EVER** in your entire LIFE disassemble a BIOS, you are then unable to program a similar BIOS without being open to a legal challenge. Even if your BIOS bears no resemblance to the one you disassembled, because you *did* disassemble it, the makers of the BIOS you disassembled can say to you, "But you saw our code and did it yourself. That's illegal." And they'd be right. Tim Massey - To unsubscribe: send mail to majordomo(a)freiburg.linux.de with 'unsubscribe openbios' in the body of the message

Now here's the catch: how do you prove a negative, that the clean room group did not indeed disassemble a BIOS, did not sneak a look at that other mailing list, etc? If you're going to do a clean room technique, you need that strictly enforced. That means being able to control **EVERY** last action of both the clean and dirty room people. The information generated by the dirty room group and the actions of the clean room group need to be strictly controlled. You need to say that there is **ABSOLUTELY** no way that the clean room people could have gotten information from the dirty room group. That means monitoring all means of communication. In our day and age, on an OpenSource project, that is not going to happen. A single e-mail from the dirty group to the clean group ruins the entire effort. We don't exactly have the resources to sequester the two groups, now do we? Compaq and Phoenix did. >The first group could make no comments about the work in progress of the >second group as that could be intrepreted as providing "guidance." The >second group >could not ask if the function was really necessary as that would be >intrepreted as asking for "guidance." > >If we are to take this route, then perhaps it is best we split soon to >avoid the process of legal "contamination." Again, it just can't happen. There are too many ways for the arrangement to be broken, and even if every member of each team did in no way break the barrier, how could it be **PROVED** that they didn't? Again, proving a negative. You need a *tremendous* amount of evidence to do this...

With these, pages couldn't be ripped out, moved, changed, etc. The problem is, what prevents me from e-mailing what I remember to the other side? Nothing. In addition to proving what actually happened (the clean room procedures), you need to prove that what didn't happen didn't happen. Without extremely tight control (a level that is impossible for a distributed group like us), it can't be done. >True enough, but the split can't be based merely on people's preferences. >Coders have to be free from any prior knowledge of BIOS source code.

What OpenBIOS should contain

by s.jacobson＠xtra.co.nz

Hello all, I see it's been busy, even if not on track ;). The basic requirements that I would have from a BIOS are as follows: 1) The ability to chainload to another bootloader ( the most basic function ), after enough hardware setup (a little RAM testing etc). The state of the processor on hand over should be a runtime option (ie protected or real mode). No dabling with V86 mode. There really isn't any need, and it gets ugly quickly. 2) A nice simple (though powerful) built in bootloader. Something like grub mainly 'cause it's got a command line which is REALLY USEFUL when you've got a system you couldn't boot otherwise. 3) The ability to boot from many media (network, cd, floppy, ide etc). Network booting would be nice but the network card support may be a bit cumbersome. 4) Some cool utilities like a nice format for common filesystem types (FAT, VFAT, ext2 etc). I think we should look to Linux for the filesystem drivers. Sam. - To Unsubscribe: send mail to majordomo(a)freiburg.linux.de with "unsubscribe openbios" in the body of the message
