It means manufacturer/model, but generally if the same driver works with both (Computer A from which the image was created, and Computer B to which the image is being sent), you're OK.
I have a SYSPREP.INF file that loads any and all controllers, including SCSI. Email me if you want a copy. You can also load device drivers that are NOT in the original system but are in the system you want to install the image to. Universal Image does this automatically but we develop universal images here manually. What you'll need to do once you have the drivers in the image is to run SYSPREP.EXE with the /pnp switch. That forces the mini-setup to do a complete renumeration of the devices in your system.
