I never got cable select to work with my rev 1 B&W G3. I used a 40-wire cable and jumpered the drive as master on the fast channel. That worked with several of the IDE drives I tried. No slave drive. Still, it was limited to one <128GB drive, and I eventually bought a PCI IDE/SATA controller card. The final fix was picking up a rev 2 G3 for $15 and combining the best parts from both to make one Mac. The other problem I have with my B&W is flaky FireWire transfers over about 100 MB. I can copy single files OK, but backing up a drive to an external FW drive never worked. It's running Tiger 10.4.11.
