When you try to partition a drive that is larger than 8 gigabytes (GB) insize, the maximum partition size may be 8 GB.
This behavior can occur if the hard disk controller does not fully supportthe interrupt 13 extensions. This information applies to both IDE and SCSIhard disk drives.
Contact the drive controller's manufacturer for information about apossible BIOS upgrade to a version of the BIOS that fully supportsinterrupt 13 extensions.
In order for a hard disk that is larger than 8 GB and uses the FAT32 filesystem to be fully addressed, it must support interrupt 13 extensions.Io.sys tests for the presence of interrupt 13 extensions. If interrupt 13extensions are not detected, the default CHS LBA limit of 7.9 GB is used.
To determine whether your BIOS supports interrupt 13 extensions, pleaserefer to your computer's documentation or consult your computer'smanufacturer.
