Dell Precision P490 SCSI Drivers

I realize this post does not belong on the OptiPlex board but there is no category for my ancient Precision P490.

Machine was running fine but of lately will not boot into Windows 7. Tried re-installing it from CD but it wants the driver for the SCSI. Unfortunately I can no longer locate the Dell CD that came with the machine when I first got it.

If anyone has these drivers, please let me know.
