My friend have a problem with his Mac?

Installing Mac OS X Tiger on Power Mac G3 B&W?

• I have fairly recently bought a Power Mac G3 B&W revision-B running at 350 with 1GB of RAM. I had it running 10.2 flawlessly besides the speed issues (its an old computer...). so i was tired of that and thought of attempting to run a little more modern version of the OS. I hate to admit, it is not a clean copy of Tiger, its a copy of the original that a friend sent me. I am not too interested in buying a new copy seeing as it is out of date and not available through apple any longer. I'd also like to mention modifications i've made to the system: -I upgraded the original CD player that came with the thing (it was old and obviously wouldn't run the Tiger DVD) -I upgraded the RAM from the original Apple 64MB stick + an extra 256MB with 4 sticks of 256 for a total of 1GB. -I overclocked the original 350mhz processor to 450mhz using the voltage jumper modification. -I added a 30GB or so hard drive to run 10.2 on as I felt the included 6GB drive was pushing it. So returning to the problem! I attempted to install Tiger from my copied install DVD. (yes i'm sure its the install DVD and not an upgrade DVD, i'd also like more advice than "get a legit copy".) I started with a reformatted drive (Mac OS Extended and Journaled). So when I booted from the DVD everything seemed fine at first. The first page I was shown was the language select. I then get the "preparing install" bar with the sideways barbershop kind of effect, showing that something is happening but not like a percentage bar or anything. after 30 seconds to a minute I get an error popup reading "Because of a problem, installing Mac OS X could not be completed" and am told to check the installation log. when setting the log to "errors only" the first error i am given is "child exited with status 10", then "Launching the installer crash log viewer". everything after that follows the phrase "crashdump[94]" I am rather stuck on what to do as I have never had this kind of problem on any mac i've updated. For possible solutions, i am rather pressed for cash so options that don't include spending any money, (ie: professional help, buying a fresh copy of osx, or buying a new computer) would be much appreciated. I'm sorry for this epically long post and props if you made it this far. All and any positive questions comments and suggestions are welcome. Also if anyone is advanced enough to diagnose the problem if i were to send them a copy of the installation log, please feel free to ask as i can post it on here. Thanks in advance.

• Answer:

  When you say "revision B", do you mean Rev. 2? The CMD chip on Rev. 1 logic boards is PCI646U2 and on Rev. 2 logic boards is 646U2-402. The CMD chip is near the left rear of the motherboard as you face the open case. You should also be able to identify a Rev. 2 system at a glance because it has a drive cage for three (possibly four) hard drives. A Rev. 1 system has space to mount only one hard drive properly attached to the case. If this is a Rev 1 system, you may or may not succeed in using it consistently with OS X. The Rev 2 system is quite stable and has a better ATA controller. You will probably have to restore the hardware to the original configuration. For that, you would need to use the original processor with no over-clocking, the original RAM (and no additional RAM), the original optical drive, and remove any PCI cards other than the original video card. Even though you may have already installed OS X on this computer in the past, you should install the firmware update at the first link below. To install the firmware update, your computer must be started in OS 9.2.2 or earlier. After you install OS X, you may try reinstalling non-Apple hardware to see if it works well. Often removing the non-Apple hardware facilitates installation of OS X, and then after the installation, the computer will run well with non-Apple hardware installed. The second and third links below are related to different types of Apple SCSI cards. Don't worry about the Ultra2 LVD update until after you get OS X installed. For the Ultra-Wide update, you would need to run the updater to enable installing OS X on a drive connected to the SCSI card. In either case, the updater only runs in OS 9.2.2 or earlier.
