8600 vs OSX vs sonnet g4/700 and bootloader crash |

hi folks- so i've got an 8600 and a sonnet g4/700 and i'm trying to get OSX 10.2 installed. i have a question, but first i'll share what i have learned: cd-rom: with 10.0, i noticed a bunch of files get copied during the first boot by what looks unix 'dd'- i saw that some of the copies failed with messages like "I/O Error" or "file not found", but i noticed that these errors coresponded with the cdrom spinning down and back up between reads. so i swapped it out with a pioneer scsi dvd-rom drive which was set to a different SCSI ID than the cd-rom i was replacing, and it worked fine. so there doesn't seem to be anything magic about using the original cd-rom drive, luckily. ram: everyone says "test your ram!", so i did. 'newer gauge pro' said everything was fine, 'provue ramcheck' froze instantly on all of my 5 sticks of ram which have exhibited no other problems. makes me wish someone would port memtest86 to ppc. in the end i concluded my ram is fine. for the record i am using an interleaved pair of 128mb dimms which i got from memoryx, in slots B4-A4. scsi: i didn't feel like extracting the hdd to look for signs of terminatedness, so i just added an inline terminator to the end of the chain. don't think this did anything. also, my scsi stuff are plugged into the 'fast scsi' slot on the mobo. i am using the built-in video; i have no other cards installed. xpostfacto is able to install 10.0 with my original 604 cpu and 256mb of ram. from there i installed the sonnet utility for osx, and installed the sonnet card. no problem- osx detected it as a g4. i don't have 10.1 to test. with 10.2, there is trouble. if i use xpostfacto to start the installer from 9.1, it goes all the way through, copies all the files, and reboots. then the new bootloader (white screen with apple) corrupts the middle third of the screen in exactly the same way (memory being written to the wrong place i guess), and hangs. if i start the 10.2 installer from 10.0, it copies a tiny amount of data (presumably just the bootloader and etc), and reboots to do the install. at reboot i get the same bootloader with corruption. consistently. i tried going back to os9 and using xpostfacto to get back into OSX, which works, but it doesn't continue the 10.2 upgrade- i'm back at my 10.0 desktop. so my questions: has anyone else encountered this bootloader crash with screen corruption? does anyone have 10.2 running on an 8600 or 9600? does anyone have 10.2 running on a sonnet crescendo/pci 700/800? is there any sort of alternative 2nd stage bootloader i could use, or any way i can reinstall the 10.0 bootloader for use with 10.2? thanks, jeff |
