hi just a quick check as Panther is failing to install on my Cube, how are everyone's master / slave settings? This HD is master and the DVDROM is slave. Apple sent me to look at KBase where it says OS X will only install from a Master but I dont know this [ and he was just reading from a webpage ]. It boots, greys, the gear spins but then hits a blue screen and stops. Booting into Verbose Mode comes up with SAM multimedia error messages, if anyone is up to speed on geek I post them, possible a RS232 error but those didnot ring bells with Apple. Similarly unable to install in Single User mode. Just preliminary as I must try the CD in another Mac [ it copies fine, the Cube passes the hardware test and there is only new good Kingston RAM in it. Full install CD. Thanks, John [ still in the M experince of Mac OS&M X ]
