A ROM BIOS provides a built-in Setup program which allows
the user to modify the basic system configuration and hardware parameters, Bios
is a set of routines that affects how the computer transfer data between
computer components, such as memory, disk, and the display adapter. The
modified data will be stored in a battery-backed CMOS, so that the data will be
retained even when the power is turned-off. In general, the information saved
in the CMOS RAM will stay unchanged unless there is a configuration change in
the system, such as hard drive replacement or a device is added. In this model we are using old type of BIOS version, looks will differ on some Machine model especially for the newer models.

STANDARD CMOS FEATURES / MAIN
- allows you to record some basic system hardware configuration.
- Time and Date Setting: to set, highlight Date /Time.
- This field records the specifications for all non-SCSI hard disk drives installed to your system. The onboard PCI IDE connectors provide Primary and Secondary Channels for connecting up to four IDE hard disk or IDE devices (CDROM’S, DVD ROM, DVD WRITER, CDWRITER’S, ZIP DRIVES). Use the Auto setting for detection during boot up.

The available options for drives A and B are 360KB, 5.25 in.; 1.2 MB, 5.25 in.; 720kb, 3.5 in.,1.44MB; 3.5 in., 2.88 MB, 3.5 in.; None. (Floppy 3 Mode Support (disabled)* This is a Japanese standard floppy drive, no need to enable.)
