Most popular operating systems available today have additional limitations which
affect the use of large capacity drives. However, these limitations can not be
corrected on the BIOS and it is up to the operating system manufacturers to release
improved versions to address these problems.

The most popular operating systems available today, DOS and Win 95, use a File
Allocation Table (FAT) size of 16 bits which will only support partitions up to 2.1
GB. A newer release of Win 95 called OSR2 with a 32 bit FAT has been released
to system manufacturers only. This new FAT size table will support partitions of up
to 2.2 terabytes. The Windows NT file system (NTFS) does not have this limit.

Once you have installed the Maxtor D540X-4K 20.4/40.0/60.0/80.0 GB AT hard
disk drive, and adapter board (if required) in the host system, you are ready to
partition and format the drive for operation. To set up the drive correctly, follow
these steps:

1. Power on the system.

2. Run the SETUP program. This is generally on a Diagnostics or Utilities

disk, or within the system’s BIOS. Some system BIOS have an auto-
detecting feature making SETUP unnecessary.

3. Enter the appropriate parameters.

4.

The SETUP program allows you to enter the types of optional hardware installed—
such as the hard disk drive type, the floppy disk drive capacity, and the display
adapter type. The system’s BIOS uses this information to initialize the system when
the power is switched on. For instructions on how to use the SETUP program, refer
to the system manual for your PC.

During the AT system CMOS setup, you must enter the drive type for the Maxtor
D540X-4K hard disk drives. The drive supports the translation of its physical drive
geometry parameters such as cylinders, heads, and sectors per track to a logical
addressing mode. The drive can work with different BIOS drive-type tables of the
various host systems.

You can choose any drive type that does not exceed the capacity of the drive. Table
3-3 gives the logical parameters that provide the maximum capacity on the Maxtor
D540X-4K family of hard disk drives.
