Has it defaulted to the nasty low-res screen, as in he can see things on the monitor?
If that is so, then there's no reason he cannot download the drivers.
If he gets nothing, then one option is to connect BOTH drives, boot from the original drive in the machine, download the drivers to "his" drive, reboot from "his" drive and then install the drivers that way.
Or, if he spends a low amount of cash, y'all can get a USB drive so you can copy the drivers to the USB drive which he then sticks into his PC so he can get his drive to install from that.
