Adding a scsi HD to a IDE HD XP system

Here is where I stand for answers.
I have a windows nt server computer on my network with 2 SCSI HD, the primary HD is bad, can not boot the server, I have a software program install on the second SCSI HD. Now when I turn on the server, access the booting options and use the debug mode but do not sign in and leave the server idle, I can access the program thru my my network from my new computer running XP Pro with IDE HD, subscesfully run the program on the SCSI HD with no problem.
The question is how can I connect the SCSI HD from my server in my new computer and be able to run the program.
I got me a SCSI PCI card install it on my new computer, but the system does not see it if I boot using the XP on my IDE drive.
