This is an absolute must for my GM45, and I've been patching it back in ever since it was dropped. I had meant to follow up after having contacted the original patch author - who claimed the patch was derived from an internally documented errata or some such - and the requirements were contrary to the GM45 publicly released documentation. The one vital testing step I still wasn't able to take is actually hooking up the S-Video output of this laptop and making sure the patch did not stop it detecting a connected TV. I don't actually own a TV, but could get access to one.. if I had an S-Video cable I could do the test! --=20 Peter Clifton Electrical Engineering Division, Engineering Department, University of Cambridge, 9, JJ Thomson Avenue, Cambridge CB3 0FA Tel: +44 (0)7729 980173 - (No signal in the lab!)
