128MB RAM tutorials do seem to be getting a little hard come by now days..
However i do RAM upgrades, but i'm based in the UK, i have a very good price range and i am willing to do upgrades world wide, please of course do remember RAM upgrades aren't available on 1.6 boxes. If anyone is interested please do PM me. Or get me email from my website in my sig.
To the guy above, if your getting error 07 once plugging in a new DVD-ROM drive, and you don't with an old one, your DVD-ROM drive PCB is faulty. Its blocking the IDE channel so the hard drive times out giving error 07 because it can't comunicate with it. Solution: replace the DVD-ROM drive PCB or the DVD-ROM drive for a whole new one.
