just bought a G4 400mhz tower with a scsi pci card. When i connect my external harddrive to the scsi card it doesnt show up on the desktop when i start the comp. Only if i use scsi probe to mount it shows up. How do i make it show up each time i start the comp? And do G3 sdram work on G4's?

It's probably a 3rd party PCI card in which case you need the drivers for it. Is it an ATTO? What does scsi probe say it is? You should be able to get the drivers from www.versiontracker.com or the atto homepage.

I bought it with the scsi card installed so i dont know what scsi card it is. I downloaded the adaptec driver so now scsi probe says its adaptec. But obviously it cant be since it doesnt mount at startup. Atto has loads of drivers with weird names. Which one ahould I try? And do G3 sdram work on G4's?

As far as i know g3 sdram doesnt work in G4's because the speed is wrong. It could have any of about 3 cards installed in it. All the way from ultra-2 to dual channel ultra-160. When the computer arrived new and out of the box it should have had the appropriate drivers installed. What CDs/documentation came with it? Have you checked your System Profiler to see if it gives you the make and model of the card? The card model should also be on your receipt.

Bought the comp from a guy who doesnt know or have any information regarding the pci card. The system profiler does not give any helpful info either. I will try and doenload and run all the versions they have at atto.

Hmmm its always fun when you have to deal with unknown hardware. Have you given it a clean OS install since you bought it? Thats always the first thing you should do with a second hand comp. It may be that the drivers are in the OS 9.1 install.

I dunno, it could be any scsi card so youll have to find out what it is before you can do anything. System Profiler SHOULD tell you what it is. Otherwise bust open the case and see if there is a label on it.

system Profiler doesnt say anything... but yes, on the card it says adaptec 2906. I downloaded the latest driver from adaptecs site the 1.3 extension. But still the same problem.

Ok then were on to a problem with the HD. Did you update the the HD with Drive Setup? Open Drive Setup, select the HD and from the Functions menu choose Update Driver.

I updated the driver from drive setup, still no result. I read at apple.com/support that moving a g3 scsi card to a g4 might require some sort of firmware, could i have a scsi from a g3? And where do i find this so called firmware. I found a firmware for a scsi card on apple.com but it didn't work on my comp. It said that it couldn't find any matching device. So how?

Well, youve stumped me. At this point i would backup the drive, reformat it, and in the process redo the driver from drive setup. If thats a no go put SCSI Probe in your control panels folder and check the "Mount scsi devices on startup" checkbox.

Weed, the "try to mount at startup" box was always checked but placing it in the control panels folder did the job. I never knew it should be placed there. Thanx!
