Can't boot with Sonnet 800 MHZ G4 card on PM 8600 |

I've been using XPF successfully with my Power Mac 8600 (originally 300 MHZ 604) using a Sonnet 400 MHZ G4 card. I'm using the stock graphics and SCSI adapters that came with it. However, I had to set the throttle to 4 to get this work (I did not need to do any throttling when using the original 300 MHZ 604 with Mac OS X 10.1.5). I've been using Mac OS X 10.2.1 on this machine for a few weeks fine. I now tried the new Sonnet 800 MHZ G4 card in this same machine, and it does not boot at all in Mac OS X (10.2.1). It boots fine in Mac OS 9. For XPF 2.2.2 I have tried increasing the throttle to the maximum value (24) as well as turning on verbose. I even tried turning the throttle completely off. In all cases it never boots far enough to display anything on the monitor. Nothing appears to happen after the boot chime I also tried booting from the Jaguar CD from XPF 2.2.2 to attempt an install. For this situation I also don't ever see anything on the screen. Before with the the 400 MHZ Sonnet Card I did not need to do any throttling for CD boot. Is there some additional debug I can turn on in XPF to see where it is dying during boot? Any help appreciated. Thanks. |

Tempo Trio Info |

I have a newly acquired Tempo Trio for my mac, which was purchased to free up a PCI slot for an m-audio delta DiO 2496 later. The card boots both OS 9.x and 10.2.x flawlessly. Something to note: If you have a >8 GB HD, you MUST partition it if used on the Tempo Trio. The reason is, unlike SCSI, or older ATA cards, which act/show up as "fake" SCSI, the HDs on the Tempo Trio in OS X are seen as *true IDE*. This means that the IDE pre-B/W G3 first partition limit applies. The driver that this card uses under OS X will be the UltraTek133.kext driver. However, when using OS X on an old mac like mine, it will show a message (if you do verbose) stating "skipping UltraTek133.kext - duplicate driver found " Don't worry about that, it will load the more recent driver. My only problem with the Tempo Trio is that in OS 9, my HD performance sucks compared to the old Sonnet Tempo ATA/66, and in OS X, while I get 2 MB/sec better than OS 9 on my HDs, they still aren't quite fast, even though they're both ATA/100 HDs. Also, for some inexplicable reason, I get *0.5x* DVD/CD read/playback speed in OS X, while it's decently smooth in OS 9. Very Annoyingâ„¢. I have contacted Sonnet about this, although it's been a week and they still haven't replied back to me yet. I hope this helps. Oh, and my PCI slot configuration, as it is now, from the "top" (closest to CPU) slot down is as follows: Radeon PCI 32 MB DDR (R7200) Empty (Used to house MacAlly USB 2-Port USB 1.0 Card Tempo Trio (Used to house Tempo ATA/66) One plus on the trio is that my Pioneer DVD-106S now can play audio cds in os x since it is true IDE! NO MORE ASSHAT PATCHED SCSI DRIVERS. WOOHOO! - Chibi Delennâ„¢ |

yohon Forgot to add. What slot is your TempoTrio in. This type of card probably works best ins lst PCI slot. Might see what Sonnet has to say about slot position in a 8600. Good Luck again! |

jpallen I think the point yohon is trying to make is that OSX.2 is not installed as yet. What he has thus far is a partial install of XPostFacto. The problem may very well be the Tempo Trio card. I have not seen too many people using this card sucessfully. yohon Might try repartioning your hard drive again making sure that the first partition is just smaller than 8gib. Use the OS 9.1 drive setup software. Then using the latest XPostFacto select this smaller partition to be the destination location. It may very well be the TempoTrio. Might try a different ATA controller card if this is a no go. I was using an Acard 133 card with no problems installing or booting but because of sound problems went back to plain old SCSI. This was on a 7500. Good Luck! |

To boot from your 10.2 partition via XPF, just launch XPF and select the partition name from the pop up menu (before you should have used this menu to tell XPF to boot from your install CD, and then it would have displayed a 2nd pop up menu to specify the destination partition). You may need to experiment with setting a throttle value (from the Thottle pull down menu. I need to set this to 4, but some others do not). Your Mac should reboot (from the 10.2 partition). If it continues to boot from the Mac OS 9 partition. Try also reinstalling the bootX and kernel extensions from XPF pulldown menu (I believe this is the file menu. Selecting them in the menu will mark them with a check). If that fails then try the verbose mode in XPF to see if it displays any info. |

**It should have restarted automatically in Mac OS X 10.2. So I'm not sure what went wrong. After it rebooted in Mac OS 9, did you use XPF to attempt to boot it from the partition installed with Mac OS X 10.2?** Hummm, how would I go about using XPF to attempt to boot it from the partition installed with Mac OS X 10.2???? This is where I believe I'm missing a needed step in finishing the installation! I feel it's going to be something simple that I haven't done. Is there something in the menu of XPF that I need to be using to finish the installation? **Have you ever successfully booted this Mac from an ATA disk (even for Mac OS 9)?** Yes, everything ran great on OS 9.1 after doing the hardware upgrade. **Also are you using the latest level of XPF (2.2.4)?** Yes, 2.2.4 **I have not seen issues like this, but I'm not using ATA in my 8600. For me the Sonnet 800 MHZ card continues to be very finicky. It sometimes requires multiple boot attempts and removal of some PCI cards. Others have had much greater success with this card then me.** I hope I don't have to do any removal of cards! |

It should have restarted automatically in Mac OS X 10.2. So I'm not sure what went wrong. After it rebooted in Mac OS 9, did you use XPF to attempt to boot it from the partition installed with Mac OS X 10.2? If so did it boot from Mac OS X or did it again boot to Mac OS 9? If it continues to boot from Mac OS 9 (using the native SCSI adapter), this may suggest it has some issues with your ATA card/disk. Have you ever successfully booted this Mac from an ATA disk (even for Mac OS 9)? Also are you using the latest level of XPF (2.2.4)? I have not seen issues like this, but I'm not using ATA in my 8600. For me the Sonnet 800 MHZ card continues to be very finicky.

Hello, I'm new to this group. I've recently upgraded my PowerMac 8600/250/96mb/4gb hard drive to a .. 8600/800MHz/875mb/4gb + 60gb hard drives using Sonnet PCI G4 800MHz/1M and ... a Templo Trio Sonnet ATA133 firewire USB 2.0 combo PCI Card with a HDD WD Caviar XL 60GB ultra ATA Hard drive .. and 875mb of Memory .(7x128mb DIMMS) I did this all under the idea I would be able to run OS X 10.2! I am have a problem installing OS X 10.2. I currently have OS 9.1 installed on the original 4gb hard drive. I have partitioned the 60gb hard drive to have a 8gb partition as the first partition on the 60gb hard drive. I made sure that the firmware was current on the Templo Trio (3.2.5) I've tried Sonnet's PCI X Installer with no luck. Tried xPostFacto software. And, When using XpostFacto software after it installed from the OS X CD to the Partitioned hard drive it did restart my computer automatically. But in OS 9.1. Shouldn't it be restarting in OS X? What am I doing wrong? Any help would be greatly appreciated. John C.

I've made some more progress since my last note. It appears the internal Standard SCSI connector change was the key. After several reboot retries, the system booted all the way up. I can then reliable reboot it again if I do a restart (or a shutdown) from Mac OS X. If however I go back and boot from Mac OS 9, then it takes me multiple attempts to get it to boot back to Mac OS X. I sometimes even have to remove the ATI Radeon 7000 and OrangeLink+ Firewire and USB 2.0 cards. It then boots into Mac OS X fine. If I shutdown and put the cards back in, it appears to boot fine as well. So it appears to be something with the transistion from booting Mac OS 9 to Mac OS X, that causes my current set of issues. I'm using XpostFacto 2.2.4. It has been running now for about a day without a crash, but Mozilla did die for some reason. So it may still have some issues. One other thing I should mention which may have a connection to the changing of the internal SCSI connector. A year ago, I was able to boot this PM 8600 with XpostFacto from the Apple factory installed hard drive with the Sonnet 400 MHZ. Early this year I replaced that drive with an Ultra SCSI Seagate drive ST336918N (narrow SCSI connector). I could not boot from that hard drive in Mac OS X with Sonnet 400 MHZ CPU until XpostFacto added the throttle option (of which I required a setting of 4). I was only able to boot from the the original 300 MHZ Power PC 604. With the Sonnet 800 MHZ, I'm currently using a throttle setting of 24. I have also seen a setting of 14 work with the Standard SCSI connector. So I'm wondering if there is some issue with the SCSI drivers in Mac OS X and newer (perhaps faster and not Apple) disks that may be partly responsible for this behavior. |

Hmm... I'm beginning to see a pattern here with the Sonnet G4/800 CPU upgrades. I too have problems, but not in OS X. My problems are in 3D games/apps (and even Littlewing Pinball's Jinni Zeala). I'm getting instruction access errors left and right that, in OS 9, appear as Type 2 errors, which are, yep, you guessed it, MEMORY ERRORS. But the funny thing is, I've done a damned lot of equipment swapping in/out, de/re-interleaving my RAM, doing one DIMM at a time (very VERY annoying since my smallest DIMMs require VM in OS 9 if used singly), and I've determined that it's almost 100% certain that my Sonnet G4/800 upgrade at fault. 2D seems fine for the most part, but ANYTHING that does certain specific Block Move or Pointer functions gives me the Insta-Type 2. Unreal Tournament (and any game using that engine) dies at startup no more than 5 seconds into any intros. Games using the Q3/Q3A engine show artifacting galore, to the point where it's unplayable due to ungodly graphical corruption. And now Jinni Zeala, which uses NO 3D elements as far as I know, also crashes on startup with a corrupt heap ("stack pointer is pointing to the wrong address"). I'm beginning to wonder if either a) Sonnet's heatsink/fan design needs reworking and the CPU is frying itself, or b) there's a really bad batch of these cards out there, or c) they just didn't test it well enough and the cards don't like our oldworld macs much. "B" seems the most likely, although I can't rule out "A", since I've felt the HSF and it's *hot*. I've only felt HSFs that hot on one other type of CPU (besides the Radeon series GPUs - those can literally cook eggs in about four minutes), and that's the Athlon series (yes, the ThermoNuclear Cores inside your PCs). I'm gonna get an RMA done on this card ASAP, and hopefully my next card won't fux0r itself like this one did. If anybody wants to see my review of this CPU upgrade as it stands for me now, go to www.xlr8yourmac.com, click on the CPU Upgrades Database link, and select "Sonnet" from the Manufacturers popup menu, and select "85-8600" from the CPU Model (Computer) menu. You'll find a very very long post by "Eric Richards" (that's me). I will reiterate, however, that I hope this is a one time "dud" card, and not a seriously flawed product (because if it is, I'm asking for my $400 back). I'll let you know what happens with my next card. Good luck with your Sonnet G4/800 :) - Chibi Delennâ„¢ |

Hmm. Now it seems to be failing in the ApplePowerSurgePE::PMInstantiatePowerDomains method. It isn't entirely clear why, though. You are getting an 0x400 - Inst access exception. I'm not exactly sure what that is, but it may be short for "Instruction Access". It would be like a data access exception, except that it is the PC that is messed up, rather than the DAR. And that is what it looks like--the DAR is perfectly sensible, but the PC (program counter) doesn't look right. So the question is why we would get a bad PC--basically, a jump to a wrong address. I tried reading through the assembler for PMInstantiatePowerDomains, and it's a little incomprehensible. Looking at the source code, there is a call to "new", and no error checking to see whether a null pointer is returned, so I suppose that could be part of the problem. (But it would be very, very odd for that "new" call to fail). So I'm not sure what to suggest. It is possible that it is some kind of memory-related error--it might be worth swapping out a couple of DIMMs to see if that improves things. I'm sorry that I can't figure out a more useful answer for this. |

Actually, I was wrong about what Gauge Pro reports. I double-checkd last night. My apologies. Your progress looks promising. The only suggestion I can offer here is based on my experience. When I get this error, usually after a game has crashed my machine multiple times, I have found that there is disk damage. I fix it by running Disc Warrior. You are able to boot with your 400Mhz card though so this is a puzzle. I don't know. At this point I would probably be leaning towards trying a clean install on another freshly formatted drive If I had one. Memory does not appear to be an issue either. What about PCI cards? I'd try the clean install with only a supported video card to see what happens. |

I never found any information on the refresh rate. However, I did try something I read in the thread "This is how I got my 9600 w/ G4 800MHz to boot" where I moved the internal SCSI cable from the fast SCSI connect to the Standard SCSI connector. With the same settings that I tried before with the Sonnet 800 MHZ (verbose, throttle=24), I now get further in the boot before it dies. Below is the debug information I now get: -------- Exception state (sv=0x02811500) PC=0x00000000; MSR=0x0000D030; DAR=0x00000000; DSISR=0x00000000; LR=0x00000000; R1=0x00000000; XCP=0x00000000 (Unknown) panic(cpu 0): 0x400 - Inst access Latest stack backtrace for cpu 0: Backtrace: 0x0008598C 0x00085DBC 0x00028B8C 0x0008F688 0x000926F8 Proceding back via exception chain: Exception state (sv=0x02811A00) PC=0x35537BFC; MSR=0x40001030; DAR=0x15E581FC; DSISR=0x40000000; LR=0x15E57754; R1=0x0E8E3B30; XCP=0x00000010 (0x400 - Inst access) Backtrace: 0x15E57744 0x0022EF24 0x002440C4 0x15E57220 0x00213A88 0x00213884 0x002141D4 0x00214830 0x00204CB0 0x00204C74 Kernel loadable modules in backtrace (with dependencies): com.apple.driver.ApplePowerSurgePE(1.2.2)@0x15e56000 dependency: com.apple.iokit.IOPCIFamily(1.2)@0x115e2e000 Exception state (sv=0x02811500) PC=0x00000000; MSR=0x0000D030; DAR=0x00000000; DSISR=0x00000000; LR=0x00000000; R1=0x00000000; XCP=0x00000000 (Unknown) Kernel version: Darwin Kernel Version 6.1: Fri Sep 6 23:24:34 PDT 2002; root:xnu/xnu-344.2.obj-2/RELEASE_PPC No debugger configured - dumpiing debug information MSR=00001030 Latest stack backtrace for cpu 0: Backtrace: 0x0008598C 0x00085F50 0x00028B8C 0x0008F688 0x000926F8 Proceding back via exception chain: Exception state (sv=0x02811A00) PC=0x35537BFC; MSR=0x40001030; DAR=0x15E581FC; DSISR=0x40000000; LR=0x15E57754; R1=0x0E8E3B30; XCP=0x00000010 (0x400 - Inst access) Backtrace: 0x15E57744 0x0022EF24 0x002440C4 0x15E57220 0x00213A88 0x00213884 0x002141D4 0x00214830 0x00204CB0 0x00204C74 Kernel loadable modules in backtrace (with dependencies): com.apple.driver.ApplePowerSurgePE(1.2.2)@0x15e56000 dependency: com.apple.iokit.IOPCIFamily(1.2)@0x115e2e000 Exception state (sv=0x02811500) PC=0x00000000; MSR=0x0000D030; DAR=0x00000000; DSISR=0x00000000; LR=0x00000000; R1=0x00000000; XCP=0x00000000 (Unknown) Kernel version: Darwin Kernel Version 6.1: Fri Sep 6 23:24:34 PDT 2002; root:xnu/xnu-344.2.obj-2/RELEASE_PPC Panic: We are hanging here... -------- Any ideas on what is going wrong now?

I believe it is downloadable from OWC's tech center section. I don't remember what version I have or which tab it is, as I have not run it in a while because it does not properly report the stats of my Sonnet G4 800, but I clearly remember seeing memory stats reported in Gauge Pro. It reported the type, refresh rate, and wether or not it was interleaved. I think it was the last tab, which I think is called memory. I'll have a look tonight when I get home to verify what I've said here. |

I tried Gauge Pro 1.1 in Mac OS 9 and it only shows the memory as 60 MB/s under the System tab. I don't see any indications on memory refresh rate. The memory test only indicates if the memory is good. Is there a newer version of Gauge Pro that shows refresh rate. Version tracker for Gauge Pro points to a location (subdir) at www.newertech.com that no longer exists. Thanks |

This is just a hunch based on my own experience of getting this card to work, and not nearly as technical as the effort you are going thru. But if you have a mix of 4k refresh and 2k refresh ram, try removing all of the 4k refresh, and make sure the rest is deinterleaved. If you don't have enough 2k ram for that, remove as much of the 4k as possible. In my particular machine (a 7500) only a pair of the 4k refresh OWC 128MB modules was tolerated. Anything I added to those had to be 2k refresh, or I got nothing when trying to boot, or very unstable operation (depended on which ram slots were loaded, whether I got that far). Can't interleave, though I suspect if I had all 2k, I might be able to. Note that I had the machine packed with 4k refresh ram before my almost simultaneous upgrade from 400/G3 to the Sonnet 800/G4 and to OS 10.2. So I don't know how much stock to put into the memory test run under your 400MHz card. I suspect my modules would have passed with my old 400MHz G3, too, because the machine ran fine. But they wouldn't work with the upgrade. |

I'm not seeing any messages from the verbose mode and I'm setting XpostFacto (2.2.4) to reinstall both BootX and extensions. I also tried using the OS X memory tester mentioned in some other posts on this system with it running from a Sonnet 400 MHZ CPU(the only way I can successfully boot this machine into Mac OS X 10.2.1) and it found no memory errors. So I doesn't appear the memory issues others reported with 800 MHZ CPU are responsible for the problems I'm seeing. |

I'm not entirely sure how to interpret the output from .registers--it seems a little odd. The SRR0 is pointing to an instruction near the end of the Main routine in BootX. If things work properly, you shouldn't get there at all--BootX calls the kernel before this, and the kernel does not return control to BootX. So I'm not sure what this means. If you were to get this far in verbose mode, you should see a fair bit of text printed to the screen first, which I believe you are not seeing. The LR is pointing to the DecodeKernel () call in the Main () routine. If you really are getting that far, then you should see a couple of messages in verbose mode first (about loading the kernel), but not the messages about loading kernel extensions yet. The DSISR is suggesting that the problem is a problem writing to memory. The DAR suggests that it is trying to write to an uninitialized pointer--that is what DEADBEEF means. So I'm not sure what is really going on here. If you aren't getting any messages in verbose mode, then I would be tempted to think that the entry point for BootX has been set improperly in your partition map for some reason, so that execution is starting at the wrong place in your code. But reinstalling BootX should fix that, and you've already tried that. |

The output from .registers is interesting--it looks like you are getting as far as loading and running BootX, but running into problems there. I fixed a couple of issues with BootX in version 2.2.4 of XPostFacto--could you give that a try and see if it is any better? If not, the output from .registers would again be interesting. |

The "default catch" is a generic Open Firmware error message--by itself, it doesn't tell you much about what happened. One thing that you could try is typing "myboot" instead of "boot" in the Open Firmware shell. That will invoke the boot-command rather than trying to boot from the boot-device directly. (The boot-command has a little bit of error recovery built in, so it might catch the error). If you still get the default catch, you can sometimes get more information by typing this command: .registers If BootX has loaded, that would give information about the state of BootX when the error occurred. If BootX hasn't loaded yet, then the .registers command will probably just give an error message itself. |
