This is what I was talking about re: "hacking" your IDE cable. You can convert a M/S cable to a CS one by cutting the #28 wire between the drives so only the first one can "see" the ground.
Interesting information on converting M/S cable to a C/S cable. With this in mind, wonder if it might be possible to use one Star-Tech bridge in conjunction with an ADP-06 bridge in a Quicksilver… with the Star-Tech set on Cable Select… and then considering the positions occupied on the cable by the drives on that ribbon cable, as Cable Select works? Would it be absolutely necessary to have two Star-Tech (or Addonics) bridges???
Here’s a bit of fun…
Beginning with an 867 MHz Quicksilver and an OWC 120GB SSD (partitioned in 3 equal partitions of 37.26GB each) with an ADP-06 attached on the last socket of the stock M/S Quicksilver ribbon cable…
First partition comprised of already installed OS 9.2.2 (with DieHard’s Instant DAW present.) Other two partitions empty / blank.
Attempted to install OS 10.4 on the second partition (A). It went through the entire installation process up to the point that the machine rebooted and normally the Setup Assistant would appear after restart. Nope. Spinning, spinning and spinning until the old gray circle with a slash through-it appears. FAILURE.
Next, successfully installed Jaguar OS 10.2 on the second partition (B) without a hitch. After installation and reboot, Setup Assistant appeared and was completed. Full boot. Stable.
Back to Partition A now… and another installation of Jaguar 10.2 over the previous attempted 10.4 installation. Upon boot of 10.2 install CD - no installation allowed on Partition A without erasure/format of Partition A first. Afterwards, installation proceeded just like Partition B - successfully. THEN rebooted and inserted OS 10.4 installation disk. 10.4 disk asked if I’d like to “upgrade” and from there installation was a success on Partition A. Rebooted and the Setup Assistant appeared… and OS 10.4 successfully was installed and booted.
So, if you don’t want to snip the #28 wire of your Quicksilver HD ribbon cable, Or if you can get by with a multi-partitioned HD and not have to buy one or two Star-Tech or Addonics bridges… you can do the install as outlined above (except for maybe the number of partitions and overall size of the SSD or other SATA drive). YOU CAN install /upgrade via the original ribbon cable over an earlier version of OS X.
Of course, always nice to have two drives on that main cable, if you want. BUT dual boot on a single HD with two partitions IS possible. (You don’t need a third partition for OS 10.2.)
