cathobie; - apologize to both for mixing up the monikers-
Glad you got it working.
On the difference of drivers between demo/actual install: I can not really advise other than the demo runs out of ram, and the install from disk- someone else chime in, is not the driver from "demo" a vesa driver ? ... I presume there is a greater range of drivers available on the install.
Then again, with internet connectivity on the demo, are drivers found and installed in the ram environment ?
still learning, even after all these years ==> BDQ
