Aaarrrrrggggh! I've spent the past two weeks trying to figure this one out. I'm trying to prepare my heavily-used 8500 for OS X. First , the environment:
PPC 8500 w/ PowerLogix Powerforce G3, a PowerPC 750 chip rated at 400 Mhz, running at 445 Mhz Backside cache of 1 Mb running at 160 Mhz (5:2 ratio). This has proven to be a stable configuration for the past 3 years. 592 Mb of RAM,currently running OS 9.2.2, having used Old World Support 1.0b7 to upgrade the machine from OS 9.1. Two Apple monitors, one running off the video card in the bottom-most PCI slot. Two SCSI drives on internal bus, Seagate ST19171WC of 9 Gb each, with 80-50 converters, at IDs 0 & 2, and Driver Version 8.1.4. The boot drive is on ID 0. Now thegoal: I would like to add larger drives, using a PCI controller and have them internal. This would allow me to install Jaguar onto a separate drive, test run it so I can evaluate the performance on this machine (I've too much legacy hardware/software at this point to move some of my workload to the non-SCSI, heavily USB/Firewire world of a brand new machine, so I'm doing what a lot f us are, keeping this old iron working). To this end, I purchased a SIIG UltraSCSI card, SC2471 V 1.0, and two IBM Ultrastar DPSS-318350N, 18 Gb, 68-pin UltraSCSI drives. And that's where the problems begin... THE PROBLEM: The PCI card has been run in both the top-most and middle PCI slots with no apparent difference. At one point in all of this, I ran the Profiler and it showed the following: PCI SLOT A1: SIIG UltraWide SCSI card, card name: pci10cd,2300 ...so I have to assume that the card is working properly. Setting the termination on one of the IBM drives appropriately (I think!), the drive shows up as SCSI BUS 2, ID-6, IBM DPSS-318350N, Driver Version 8.1.4. I THOUGHT I had successfully format and initialized the IBM drives with the most recent version of HD Tools that came on my 9.2.2 install disk. Everytime I try to move any files over about 50 Mb, the read/write red light comes on on the SIGG card, the cursor turns into the clock and everything stops. Yes, I still have mouse movement, but keyboard input disappears and the whole thing seems to be hung. I first noticed this when I went to try and install an OS onto the IBM drive to see if I would be able to boot from the PCI-based drive (yes, it SHOULDN'T be problem, but I wanted to be sure). The install simply hung and I had to use the Command-Ctrl-Power abort/reboot to get the machine back. Thinking that perhaps, a full reformat would clear up any problems actually seemed to make matters worse... I couldn't get HD Tools to see the drive. Force reboot, shutdown properly, disconnect the drive, reboot, check the Seagates, shutdown, reconnect the IBM drive, reboot. Drive appears in HD Tools, but format hangs. Force reboot, shutdown, disconnect, reboot, shutdown. re-connect, reboot, drive reappears. I have a licensed copy of FWB, but I'm concerend about some of the issues that have shown up here on the list about using it to format drives for use with OS X. I'm running out of ideas of how to approach this and I'm afrraid if I keep having to crash and burn, I'm going to frell my Saegates AND the IBM drives to the point that I won't have a stable system any longer. I've tried to make sure that I haven't done any damage to my file system onthe Seagates (I was starting to have some minor problems that were "fixed" by the Apple First Aid, but again, I'm trying to err onthe side of caution here). Has anyone seen this before? Any experience with this PCI card? Any experience with these drives? I really can't simply pop an adapter on to the SCSI connector of these IBM drives and swap them over, one for two, with my Seagates, though that had been my original idea. That's why I bought the SIIG card, which would actually give me more flexibility with making the move over to Jaguar. For what it's worth, I have been completely successful with using XPF to get OS X 10.1.5 running on a straight stock 7600 with 128 Mb ram, on two 4 Gb drives and a 13" Apple RGB monitor. We use it as a web- and fileserver (http:angrek.net) and while not blazingly fast, is actually a comfortable working environment. So I'm not a complete newbie with this.
