Need Help with SCSI Card and Drive

I got the SCSI PCI card as a built-to-order option.

There is a firmware update for those PCI slot cards, to allow them to function in an OS X environment. Either of these two, depending on which card you have:

60409 - Ultra SCSI Card 1.2 Firmware Update: Document and Software

25176 - Mac OS X 10.0: SCSI Card Updater Document and Software

Hi Tyro,

I may have the answer for that one. I have an Adaptec 29160N that was doing the exact same thing in OS X Panther when I first installed it.

First, find out if the built to order SCSI card is the same type (I think it is). Open the System Profiler and click on "PCI Cards" in the left pane. Highlight the SCSI card in the upper right pane, if it isn't already and check the information on the card below. If it's the same as mine, it should read "ADPT,29160N".

If that's right, install this driver from Adaptec's web site. It says beta, but it's been that way for over a year now. However, once I installed that, everything worked perfectly again.

Hmm, I used to have that same card in a dual 450 G4. That one didn't need any extra drivers under Panther, but I'm not sure about Tiger. You could try this driver instead, since it's specifically for the 2930.

The really confusing part is if you look in the Extensions folder within the System folder, there's already drivers there for both the 29160 and 2930. Odd that they won't work.

Ta daaaa! Glad that worked for you, Tyro. 🙂

I have a 2GB Jaz drive that's giving me a few problems. I had it in this B & W for years with the same Adaptec 2930 SCSI card. There was an internal hard drive at the end of the chain with the termination jumper installed and the Jaz installed in the center ribbon position. This was also a working dual boot machine with 9.2.2 and X.2.8

I recently removed the entire SCSI chain while moving hard drives around with other machines, troubleshooting a seperate RAM problem, and restoring a crashed FW external drive. Geesh a lot has happened in the last 2 weeks!

Anyway, I finally got the B & W working again as a dual boot machine but with Tiger X.4.3 and 9.2.2. So now I want to put back the original SCSI chain and nothing but problems now.

I can still boot into 9.2.2 just fine... but not in Tiger without Kernal Panics.

Configuration #1- Jaz drive on center SCSI ribbon position with termination block installed on end of cable as per factory specs. Can't boot Tiger without kernel panic.

Configuration #2- Jaz drive on center SCSI ribbon position with Hard Drive on end position and termination jumper set on HD. Same results as #1 above.

Other Notes-

1. Insert any disk in Jaz drive and computer will boot into Tiger and mount disk.
2. Remove power cable from Jaz drive and compuer will boot into Tiger.
3. Eject disk after booting into Tiger and get Kernel Panic very soon after.
4. All configurations appear to work in OS 9.2.2

I've changed the SCSI card's internal terminations to all three settings with all the above results the same. I used to always have it on "disabled" and now it's on "automatic".

I've downloaded and installed the 2930 OS X drivers from Adaptec even though they state- "The version 1.1 driver is embedded in Mac OS X 10.2 and later, there is no need to download and install this driver if you are running Mac OS X 10.2 or later."

So now all the B & W hardware is back to where it's been for years and I can't boot into Tiger. If I re-install Tiger, it has to be from scratch since the installer detects a newer system version. Plus after booting into the installer, it froze up while I was just looking at the "options" screen for installing.

I'd ultimately just like to just have the internal Jaz by itself but I put back the hard drive merely as a means to troubleshoot.

I don't know if I have an Iomega issue or an Adaptec issue??? Iomega's web site has a KB doc in the Mac section that seems to be written for a PC. It says that the drive is setup to boot in the bios. Adaptec's web site refers back to the device manufacturers when the computer won't boot.

Added the following-

Configuration #4- Jaz drive mounted in external SCSI case with hard terminator installed. Same problem- can't boot tiger without a kernel panic.

All notes same as before. Can boot Tiger but only with Jaz disk inserted or only with power removed from drive.

Apparently there is an issue with a single outdated Apple system extension and Tiger.

Reading this entire thread shows many people with symptoms identical to mine...

My problem was fixed by just deleting the file mentioned in the later half of the thread.
