I have posted a few questions, and I have found the answers...first, some copies of jaguar won't install properly on the ibooks...it's a retail version too...but when I try to install onto a ibook 12.1" it gets a funny small screen as soon as it gets to the blue splash OSX screen (I had bought this ibook with no system cd's)...so I bought yet another ibook, a 700 so I could get the ibook install disks and use them for my ibook 800....the osx version is 10.2.1 and it installed no problems at all (then updated to 10.2.8_)...I then installed OS9 (software restore) and no problems...so the phantom monitor that I was having was resulting in the wrong version of OSX and OS9....I needed the original disks...what I thought was a hardware problem (phantom monitor) was a software issue...the retail version of Jag exibitied the exact same result on the ibook 700 so I knew if was the software for sure...just in case anyone else has the same problem out there...you need the original disks...Mark as far as the fan noise...the ibook 700 has the exact same sound and it's not there all the time so it must be normal! we hope!...cheers, mark
