in your 1st post you said you are new to Solaris I'm assuming here that you have OpenSolaris installed, If that's the case have you tried to run the Device Driver Utility?
In your 2nd post you asked about the whereabouts of the drivers, you can look in the following:- 32bit /kernel/drv 64bit /kernel/drv/amd64 -- This message posted from opensolaris.org
