The above post assumes that...
1. The machine is still bootable and you can get into the software that creates the recovery cds
2. The machine hasn't be monkey'd with and/or the hidden recover partition is still intact. (ie. a replacement hardrive for example)
3. The age of the machine is recent enough to even have a recover partition, as he didn't provide us with a model.
4. The drive is even still funtional, which we dont know as he didn't tell us why he needs the recovery CDs.
If we are to assume that the hard drive is in working condition, that a recovery partion still exists, then try turning the unit off. Hold down the 0 key and power it back on. (continue to hold down the 0 key through this process). That may restore it to factory. Of course depends on the model.
