Config Hard Drive for Mac?

[Eric House]

Does anyone know which jumper settings other than the address settings need to be shorted? The Mac won't boot with the hard drive installed. It might be a termination problem. Is the hard drive terminated? I'm installing it as a second hard drive. The hard drive is an HP C2247.
Thank You

Eric,

Unfortunately you didn't mentioned if we deal with a C2247 Single-Ended or Wide-Differential.
I guess you use the Single ended, right?
Basically you have the following jumper:
Write Protect
Unit Attention
SDTR
Parity
Auto Spin Up
Sync Spindle

You want to short "Auto Spin Up" (5). Parity checking is enabled, if the parity jumper (4) is shorted.

An other interesting jumper block is on the top of the disc controller. You will find two rows of jumper pins. One of them is Terminator Enabled. Remember, all SCSI buses have to be terminated on both ends. If you already have the ends of the SCSI bus terminated, you have to remove this jumper.

First of all thank you for your response.
Out of the group of jumpers you listed:
Write Protect
Unit attention SDTR
Parity
Auto Spin Up
Sync Spindle
I should short Auto Spin Up and Parity only?

To be honest, I know the disk, not the Mac (I live in the UNIX world). I have no idea if this box has parity checking or not. But the parity jumper should be a 'don't care'. If it's set wrong, your system should react with a bunch of error messages, but it should boot?
Do not short write protect. I assume you will still have the capability to write to this disk.
Unit Attention should be open.

Does the Mac recognize the disk in any way? If yes, I would check the termination. Remember both ends of the SCSI bus must be terminated. Nothing more, nothing less

Has anyone gotten the HP C2247 hard drive to work on a Macintosh? I still have not gotten it configured for the Macintosh. The SCSI probe will recognize it, but I can not get it working.
