* I'm currently [Feb 2001] talking to Adaptec about this redistribution
* issue. Stay tuned...
* If Adaptec could allow redistribution of the firmware (even in binary
* format), life would become a lot easier. Unfortunately, I've lost my

* occur. If anybody from Adaptec reads this and can help with this matter,
