What's a Floppy Disk?

We have a rather difficult problem which has taken us some research to possibly resolve.

One problem with old motherboards is that they are unable to recognise hard disk drives above a certain level. One way to get over this is to put on a "cap" jumper. The motherboard should then recognise the HDD but its capacity would be limited to the maximum allowed by the motherboard. We thought that it would be necessary to update the BIOS, and to do this we needed to use a floppy disk (whatever that is - I think I have some vague memory of things like that!!)

The actual problem was, however far more complex, and to date has not yet been resolved.

Other problems this week were a set of disappearing shortcuts and a problem with installing a new printer.
