Still would not install. Same half install process to black screen that you experienced.Tried all of 128 sticks and various combinations thereof (BW originally had 512 MB).Still would not install. Knowing that OS X.3 is extemely picky about RAM. Finally went and pulled a clean 512 stick from my DA (133 Mhz RAM no less), and the install went fine. Shut down, re-installed the four 128 sticks of 100 Mhz, the SCSI card,PCI USB,PCI ATI and everything has worked great for the past two years. Just my experience. Maybe it will help. Wade Perry
