Older BIOS that only support Int 13 commands for accessing ATA drives through
DOS based operating systems will be limited to use only 1024 cylinders. This will
reduce the effective capacity of the drive to 528Mbytes.
Whenever possible the Maxtor D740X-6L 20.0/40.0/60.0/80.0GB AT drive
should be used on systems that support LBA translation to ensure the use of the
entire capacity of the disk drive. If that is not possible the following are some
techniques that can be used to overcome this barrier.
• Use a third party software program that translates the hard drive
parameters to an acceptable configuration for MS-DOS.
