WebThe BIOS uses the traditional CHS (Cylinder-Head-Sector) addressing scheme, which requires three numbers to specify a sector. Unfortunately, the number of bits allocated for each number was chosen rather small, limiting the accessible disk size to about 8 GB. Newer BIOSes have addressed this deficiency and have defined a set of new, extended ...
