G4/001 extension set

I want to optimze my extensions for PTLE. How do I know which extensions are necessary for the Mac OS to run smoothly with LE and which ones I can turn off in Extensions Manager? I've been experimenting but would like some feedback.

Howzit tb... recently someone posted this link... It has a description of most of the common extensions and what they are used for... it helped me create an extension set for PT that only takes up 29mb... try it... //NW

We test and support all of our software for compatibility with the Mac OS Base+Digi extension set. Therefore, you need not disable any additional extensions that are part of the Mac OS Base set. As a matter of fact, many of the system extensions serve multiple functions. Therefore, you may cause yourself unnecessary grief if you start disabling beyond the Mac OS Base set. Brent

Don't you have your internet software enabled? Will PT will stream online for you? I am sure I read this, but I cannot find what publication it is in. . .JT

I also used that logic post with great results except now on startup i get a message saying usb extended keyboard driver missing. Everything works fine and all usb extensions are on. But I'm sick of the message. Any clue?
