DISC DEPRIVATION

It is now common practice to purchase PCs with pre-loaded software, often without copies of the latter on disc. In theory, the basic operating systems of DOS and Windows can be copied on to floppy disc. However, it is my understanding that some files are not copied by the normal MS Backup command. Therefore, in the event of a hard disc failure how can I be sure that I have full copies of the original software?

Many PC manufacturers, or OEMs (original equipment manufacturers), have third-party licensing agreements with software companies such as Microsoft, to supply bundled software with their machines. It is up to the OEM whether or not they supply discs and documentation as well. Many do not, and that’s usually reflected in a lower retail price. On balance this arrangement works in the PC buyer’s favour, with a machine that’s ready to go, loaded with several hundred pounds worth of software. The main disadvantage is that if there’s a problem, you have to seek help from the PC supplier, rather than the software company. As far as making your own backups are concerned, MS Backup will allow you to duplicate all the files necessary to create a backup and rebuild your system. As a matter of interest a typical Windows 95 backup will occupy around 25 floppies...

MOTHER OF ALL BOARDS

In a recent reply to a query you indicated that you can upgrade a 386 PC to a 486 or Pentium by changing the motherboard. How difficult is it, and what precisely is involved?

It is a relatively straightforward job, undoing a few nuts and bolts, swapping  cables and boards and you won’t need any specialist tools. However, there’s a few points to bear in mind, before you whip out the screwdriver. Firstly, some larger PC manufacturers use proprietary or custom-made motherboards, and you may not be able to get hold of a suitable replacement. Second, if your PC is getting on a bit you may find that you’ll have to upgrade other components as well, like the hard disc drive and graphics card; you will probably need extra RAM memory too. In the end it might be quicker, easier and cheaper to buy a new machine. If you’re determined then it is a good idea to read up on the subject first. The Idiots Guide to Upgrading, by J. Fulton,  from Que New Users, and Upgrading and Maintaining Your PC by U. Schueller, published by Abacus Software -- available from good book shops and larger computer stores -- are good places to start.

WET SET

Do you know of anyone who makes waterproof ink cartridge for a Hewlett Packard 500C printer? I’ve tried asking HP without any luck. Waterproof refills I have tried work, but they clog the cartridge after the first filling.

Hewlett Packard have confirmed they do not supply cartridges with waterproof inks, for the very reason you mention, namely that they clog the print nozzles. We contacted several specialist companies who market inkjet refills and they all said more or less the same. The only thing we can suggest is to treat any print work that’s liable to get wet, with a protective spray, like Copyguard.
