- You can use the MAC Adress of the LAN boards (if present) of PCs to
- uniquely identify them. You are ensured that this adress is unique.
- If the PC has no MAC@, do NOT rely on a BIOS signature (Flashable BIOSes
- would break), neither on RAM or Hard Disk size, which may be upgraded
- quite often.
-
- One other good point to consider is to use DMI. DMI is a specification
- that allows you programatically to retrieve lots of information about
- a computer. The drawback is that it is only one or two years old, so
- older PCs may not implement it.
-
- You can get some info about DMI from http://www.intel.com
