I should have said to pull the mobo cache. It has little benefit compared with the G3s backside cache, and may be doing you harm.

You do know that the FPM Ram controller will have to add wait states because the FSB is running that fast. I had my 9600's running their buses at 54MHz, the CPU was running faster but the system seemed slower overall because the RAM wasnt accessible as often.

Your Sonnet G3/500 is driving the TNT mobo in the 7600 at 50 MHz. This is the limit of what a TNT can do. At this speed, TNTs can be very picky about RAM and L2 cache. This along with your various PCI cards is likely making your system unstable under OS X.
The SCSI CD ought to be fine if it's original. If it were me, I'd strip down the system to its essentials, install on that, then gradually refit the extra hardware testing each time for stability. I'd use XPF 2.2.5 for this Jag install.
You haven't listed your drives. TNTs with OS X are picky about internal SCSI as well.
I have five such TNT mobos. All are capable of running OS X. Each has its own personal limitations about the combination of RAM/interleave/L2/bus-speed/SCSI it is happy with. Get them wrong and the symptom is intermittent freezing and similar instabilities, as you have described. Get them right and the machines run 24/7 for months.
Obviously, don't commit critical work or data to this machine until you've beaten it into good behaviour.

Dear List:
After several unsuccessful attempts at trying to install OS X (v 10.2) on my Power Mac 7600, I decided to try
disabling the L2/L3 cache option and then clicked INSTALL. The installation started, paused a few times and then
after much tense waiting the GUI finally appeared and Jaguar was on its way to installing on my 7600.
I checked the installation this morning and I noticed a few odd things. I tried running the Software Updater, but it
refused to install the necessary components. A message stated that there was a problem installing the software. I
downloaded the 10.2.6 Combo Update, but when I tried to install this software the installer unexpectedly quit. When
I tried to launch iTunes, it unexpectedly quit. On the other hand, when I launched Internet Explorer, it successfully
launched and allowed me to browse without incident. I have also noticed on several boots that the system hangs at
the OS X splash screen or a dark greyish background with a white message window appears asking me to restart the
computer.
Inside my 7600 I have the following components installed:
1. SIIG Altra ATA controller card.
2. ATI VRRagePro graphics card.
3. 256MB OWC RAM.
4. Sonnet G3 500 upgrade card.
There is also my old CD-RW attached (which used to reside inside my G4 466 until I swapped it out for a Pioneer
Superdrive) to the ATA controller which I used to install OS X on the 7600 since I was unable to use the stock SCSI
CD-ROM in the 7600.
Can anyone here offer any insight about what to do at this point?
Roland :)
