Size
This setting indicates the size of the drive, normally in decimal megabytes. This actually isn't really a "setting" per se, since you don't normally enter this value. It is calculated according to the following formula:
- Size = (Heads * Cylinders * Sectors * 512) / 1,000,000
The 512 is because PCs use 512-byte sectors; the 1,000,000 converts the number to decimal megabytes. The number of heads, cylinders and sectors in this formula is equal to whatever the settings are in the BIOS.
