Okay, Another question I learned on this forum that I needed to have my internal SCSI chain on the slower buss instead of the normal FastSCSI buss. I would really like to have the performance boost being back on the other FAST SCSI buss. Has anyone made this work on a PM 73, 75,7600 machine.....???? |

I only use SCSI drives and have never had a problem with them. I used to use the native bus but now use an Adaptec SCSI card for Ultra160 drives. The key to success is good cables and accurate termination. OS X is very picky about termination. BTW, I'm using a PM 7600 with a Sonnet G4/800 mhz upgrade. |

I couldn't use my internal SCSI a long time ago installing the public beta. I had an IBM drive and for that model I needed to disable unit attention on the drive to use it on the internal SCSI. |

works for me |

the internal fast SCSI bus works fine for me on my 7500 w/ 2 hard drives, CD-ROM, and floppy drive. |

Some people have problems with the internal SCSI bus, but by no means all--in fact, I haven't had a problem myself. |

cschmidt Placed OS 10.1 Install Disc 1 and/or OS 10.2 Install Disc 1 in original Apple CDROM drive whic is on internal fast SCSI chain and installed it to a 9G Seagate SCSI drive connected to the same internal chain. The Seagate drive was terminated as it was at the end of the chain. Used XPostFacto (who knows what version) to select either Install Disc as the drive to install from and then selected the Seagate as the hard drive to then install it to. I probably at that time also used the built in video port to make things easier. |

I think that may have been true with older versions of Xpostfacto. It was so long ago I forget what I did to get it to work but I have an internal LaCie SCSI 18 GB drive using a Mac 7300 with a Sonnet G4/400 card and OS X boots fine from it. |

I have a PM 7500 also. I only use the fast scsi bus for a internal burner, the narrow not at all. I did all my X installs through an Apple Atto scsi card PCI/PSC from Otherworld. I haven't tried the Apple Atto UL2 card to install just got it today. On a 7500 you need a Apple OEM CDROM and the built in video attached with no adapters pluged in any other video slots on the back. After installing a scsi card or any card for that matter hold down the chuda botton for at least 45 seconds before booting. It may take 5 mins or longer for the computer to open the card. After in boots probably into OS9 zap the pram then restart several time after that to imprint it on the system.Take care of your OS9 partition. That is the system native to your comuter. You'll really need it if anything ever goes wrong and it will. |

I have never had to use the slower SCSI bus to install. Current system is PM 7500 with G4 800 upgrade. My initial install was OS 10.1 when I had a NewerTech G3 400. No major problems with hard drive connected to fast internal SCSI bus. Did nothing special that I can remember. The hard drives were formatted with Apple's Drive utility while booted in OS 9.1 |
