how do you reformat a PC ?

You don't configure partitions from BIOS settings.

In BIOS settings, you make sure that the BIOS has identified the hard drive properly.

Depending on your Operating System, and motherboard, you either use a "Boot" floppy, (W9x, NT) or Boot from the CD for the OS (Me, W2K, XP).

If you boot from the floppy, at the A: prompt, type in fdisk and press the enter key.
Follow the options to partition the drive as desired.
The primary DOS partition on the 1st physical drive must be set active, and is your default boot partition (C:).

For more details, check out www.fdisk.com/fdisk
There is also a good article on partition stratagy at www.aumha.org

After setting up the partitions, I prefere to format at least the C: drive from theboot floppy.

If you are installing from a bootable CD, just follow the prompts to set up your primary partition.
You will need to enter the disk management console, or boot to a startup floppy to set up the extended partition.

You need ether a win95 boot disk or a computer that can boot to a cdrom. To find out if your computer will boot to a cd, as the computer boots up you will see something like press esc to enter setup or press f2 or something like that. Do that and depending on your bios it will be advanced settings or some other choise, look through them. One of them should give you a choice to which device to boot to pick cdrom and put you O/S cd in and select save.
