I would like to upgrade the bios, for instance, I would like more accurate temperature and fan speed readings. However upgrading the bios is dangerous since, if anything goes wrong during the process the computer will not work and until a new BIOS chip is ordered and installed. There are a lot of reports on the Sudhian newsgroup about problems during bios updates and a lot of people there suggest using the Bios Savior.
The Bios Savior model number required for Shuttle SN25P is : RD1 PMC4
I got it from here because I'm in the UK and because they also had some sata cables that I needed. It can also be bought from here
Inside the box is the memory chip in the socket along with a switch and a card back plate to fit it on. There is also a chip removing tool.
Here is a picture of the socket/chip assembly:
Here is the other side which fits into the motherboard:
First I screwed the switch onto the card backplate and put the backplate onto the Shuttle:
The cable is threaded across to the other side where the bios socket is on the motherboard.
The switch on the back plate:
With the graphics card re-installed.
This is as far as I have reached for now.
