Adaptec SCSI cards w/Xpostfacto |

I have been running OS X 2.1 succesfully on my PowerTower for the last several months. However, I had to remove my adaptec 2930B SCSI card in order to install OSX using Xpostfaco. Now I can't get it to boot when I reinstall the card. I can only get a succesful boot when I'm using the SCSI motherboard port. Is there a work around to allow this card to be used? If not, what other SCSI cards are know to be conflict free? Steve |

Okay, having some trouble with the 29160 card. Getting a ROM error when I try to flash it to be a Power Domain. Bummer, I might have to pull out the solder and go at it to swap out the ROM chip. Now if only I could get a cheap ROM somewhere.......... Might throw it in the WinDoze machine, and live with the 2940 in my MAC. |

I just got a 29160N, it is OEM (probally windoze), but I will try to flash it to a power domain firmware. I will keep you posted, I had good luck flashing/converting the 2940 card, but I would like to boot from this card, which the 2940 does for 9.2 but NOT for X.2.6. The card was 50 bucks, so what the heck. |

BTW- Though I am running my wintel flash hacked 2940 with two drives on it in 10.2.6, it does not boot in OS X. It IS great for additonal storage drives, and DOES boot from the 9.2 disk on it. See previous thread by me....... |

Are you saying you can boot from a 2940? I think the deal with the 2940U2b, is that it boots ok in the B/W G3 and newer running OSX. I does work in the Old world macs, I have on in my server hooked to an 18gig drive, which has been running OSX server for a long time (since 10.0.3). However the 2940U2B is NOT BOOTABLE in my experience. It produces a delay at startup, and then the screen flashes back to the OS9 grey screen. Of course I haven't tried updating the firmware or fiddling with it in a long time either... Marty |

I flashed a 2940 card from a wintel machine to be a power domain. Works great in os X AND 9.2. OSX just picked it up and id'ed it as a 2940!! I am running 10.2.6 on a 9500 |

The 1.2 firmware for the U2B is old, is on Apple's site, pre-dates OS X PB. The seller is selling you snake oil. Apple dropped support of the U2B in 10.2.2. The only system it probably does work fine on, is the B&W for which it was originally intended. Originally I had two of them to create a "dual channel".... that is until I found out that the PCI bridge in the B&W hampers write IO's to 53MB/s max. Then I put in a UL3S, no better, so then I got a 66 MHz 39160 and use that in the video slot. I dont' need great video for Jaguar and surfing the web. |

The 2940U2B with firmware 1.2 (download available from apple or vendor below) is supposed to bring OSX compatibility, according to seller MacResQ.com a few weeks ago (don't know if they still have it). But I haven't tried it. |

With vintage systems it is a mess. The old ATTO PSCd has narrow UltraSCSI and wide/SE which I've used in 7300 with some success. The UL2D should have worked okay but it seemed that if you got it working in Jaguar there was trouble with 9.1. You may just need newer ROM (firmware) on the card as 2930CU is still supported and what Apple was using as BTO on G4s. OWC still sells them. The 29160N is almost overkill for the price, but it should work. I'm using 39160 and that only started working satisfactorily with 10.2.4/5 and the 12/2002 kernel extension. |

I believe the best drivers for the 29160N are included with 10.2.X. There have only been a few updates since 10.1.X, so I think you shold be all set. I don't think you can use the cards for Wintel machines. I think the firmware is different - at least for booting. If you want a fast card, I think the 29160N is the way to go. I didn't think the 2940's were supported, and the 2930 is just too slow. I know the cards are not cheap, but they do make a killer controller. I've seen them on eBay, so you probably just have to keep looking... |

I have my PowerCenrter Pro working with the Adaptec 2930B that came with it. I tried it in my 9500 and it would not even boot into 10. I am not sure why it works in my PCPro and not the 9500. The Adaptec 2930 commercial version or the one that came with the Blue and White G3 is directly supported under OS X. As per some documents on Apples web site. I'm sure Appe doesn't support it in a PowerTower Pro running OS X. No version of the 2940 is supported by either Apple or Adaptec in OS X. Then again my 2930 is not supported and is definately not supposed to be bootable. Now I understand that ATTO has a wonderful card. The fellow who develops the OS 9 Helper says he got a card flashed and all. He seems to hightly recomend the card. |

Thanks for the feedback fellas, Did you have to install any special drivers for the 29160N or does OSX have them built in? Also-- I noticed several of these cards on e-bay but none listed for the Mac. Will the Wintel PCI version work on the Mac or is the Mac version a different beast? I know this is the case of most of adaptec's cards. Steve |

I've been using the 29160N from the beginning without incident. I highly recommend these cards. I matched it up with one of the OWC IBM OEM drives (36G) and it screams. On disk related operations, my 8600 w/G3/500 is faster than my powerbook G4/867. If you get one of the OWC drives, just remember that you need to either hack the OS 9 version of Drive Setup, or get one of the third party SCSi formatting utilities. I have had good luck with both options. |

The 29160N works ok, and is bootable, but the 2940UW is sketchy and non bootable, and the 2940U2B will not boot, but seems to run ok. Sorry I have no 2930 to test... Marty |
