Should be a small, hidden partition on the original hard drive.. which contains the drivers and install setup. Typically, when you first use the computer, you are prompted to copy that partition to an optical disk.. for future reference. Use the Disk Manager
feature of System Tools
to activate that partition (if still there) so it can be accessed and copied to an optical disk. Likely it is around 500 megs or so.. possibly including the OS intended for the system.
You could use a free diagnostics program such as CPU-Z to ID the basics of the laptop.. such as processor type, memory and chipsets. Get it from http://www.cpuid.com/cpuz.php
F@H.. to solve mankind's maladies.. in our lifetimes!
