This is related to a Compaq/HP patent for CS whereby the device characteristics of the attached drives may be more easily determined, and the motherboard chip thereby may be more easily set as to speed, etcetera. This procedure requires a cable which is set up for CS so that the host adapter may determine if a 40-wire/40-pin cable is attached, or if an 80-wire/40-pin cable is attached, and if the latter, then the speed of each drive may be interrogated by sending a special reset sequence to each of the attached drives. > When I get the new drive, how do I set it to be the slave to the > Quantum?

By convention, the optical drive is always master and the Zip, or a hard drive which is installed in place of the Zip, is always slave. Also by convention, the lower drive of the two-drive carrier is always master (although it need not be, if a second drive is also present) while the upper drive of the carrier is slave. On the two-drive carrier and the HD bus, you may freely interchange master and slave as long as two drives are always present. Typically, I initialize new HDs in the Zip bay of the optical bus (I have NO Zips on any of my machines). Therefore, this HD is always slave. After testing is complete, I may then move it to the two-drive carrier, also as slave, but I could just as easily move it to the two- high carrier as master, retaining the slave which may already be there. (This allows for a lot of flexibility when CCC-ing backup or duplicate drives.) Most of my remaining G4s ... and I have about a half-dozen of them ... use a 160 GB master and a 500 GB slave, on the two-high carrier. The 160 GB drive has 10.3.9, 10.3.9 Server. 10.4.11 and 10.5.6 in the under 131,072 MB area, with about 25 GB left over as "scratch" (usually used for temporary storage for Toast). The 500 GB drive is a pure data drive and is generally partitioned as 131,072 MB and about 338 GB. With the availability of the LBA48 Property script for all G4s (and possibly for the B&W and Yikes! as well) I could operate the drives without the hard 131,072 partitioning, but old habits die hard. Incidentally, I just yesterday acquired a QS 2001 to which had been applied a firmware update which gave that machine permanent large drive capability without using the LBA48 Property scripts. I tested this fact by executing a reset-nvram in O.F., and after the reboot the 200 GB drive was still seen as 200 GB and not as 128 GB. For non-QS machines, the LBA48 Property scripts remain an option. http://groups.google.com/group/hq-a <+> A home for the Hackintosh community.
