- OK, so they are trying to protect this as a "trade secret". If

- Or, unless someone discovers the secret and blabs.

- One can discover the trade secret without disassembling the BIOS.
- [disassembling the BIOS is probably legal, too, since this comes
- under the fair use provisions of the Copyright laws; I've never
- yet seen a shrink-wrap license wrapped around a VGA board which
- would put additional limits on fair use like software licenses.]
-
- One can put an emulator into a PC (or just a logic analyzer will do),
- run the BIOS, and see what I/O's are going out to the board to set the
- clocks.
-
- The Diamond 24X is likely to be fairly ubiquitous in the cheap clones
- (I think Zeos ships it, for example), and these are, of course,
- exactly the type of people who'll be wanting XFree386. I think
- Computer City is selling them for $175.
