Panther 10.3 on 7500

[Kris Tilford]

I used 3.0a8 to 'upgrade' from an archive reinstalled 10.2.6 to 10.3.1 
on a 7500, XLR8 G4/400, 544 MB, Radeon 7000, SCSI bus drives. No 
problems at all, except that the upgrade was very slow because I didn't 
use the enable L2 / L3 cache check box in XPF 3. I'd already been using 
PowerLogix Cache Control 2.1b4 and didn't want any conflict on the 
restart. It appears I should have uninstalled the PowerLogix for the 
installation, and then the upgrade would have been hours less. I 
estimate 3+ hours without L2 vs. less than an hour if I had L2.

The PowerLogix Cache Control still works fine in 10.3, and I used it 
because for some reason the previous XPF cache control only enable mine 
at a 4:1 ratio instead of 2:1, which in the PowerLogix is adjustable. 
Unfortunately one of the neat features of the PowerLogix doesn't seem 
to work in 10.3, that's the 'fixing' of Apple System Profiler. My Apple 
System Profiler says 'no information' for SCSI bus, and PowerPC 60? 
(2.9) for CPU Type. On the other hand, the FireWire bus gives great 
information on every device, even a flakey external 2.5" HD that won't 
mount on any Macintosh. That valuable info might enable me to find 
updated firmware to fix this useless enclosure?

To me everything seems much quicker than 10.2. Quartz Extreme works 
after reinstalling PCI Extreme. Everything else seem normal or quicker. 
So far, so good.

I will be transferring over to a Firewire booting System soon, so I'll 
report on that also. If anyone has experience with OS X and RAID 
software, perhaps SoftRaid, I'd like to hear about it on a new thread 
or e-mail. I played some with the OS X Disk Utility RAID and the lack 
of partitioning really makes it useless to me. Kris Tilford
