Normally the “Standard CMOS Setup” allows user to configure system settings such as current date and time, type of hard disk drive installed in the system, floppy drive type, and the type of display monitor, etc.. These settings can be lost or corrupted if the on-board CMOS battery is failed or weak.
Date and Time
1. Date : Type or select the current date for your system.
2. Time : Type or select the current time for your system.
Hard Disk Configuration
1. TYPE : (e.g. Select from “1” to “45” ) to fill remaining fields with redefined values of disk drives. Select “USER” to fill the remaining fields. Select “AUTO” to detect the HDD type automatically.
2.
SIZE : The hard disk size. The
unit is mega bytes (MB).
3.
CYLS :The cylinder number of the hard disk.
4.
HEAD : The read/write head number of hard
disk. (e.g. The range is from “1” to “16”)
5.
PRECOMP : The cylinder number at which the
disk drive changes the write timing.
6.
LANDZ : The cylinder number that the disk
drive heads (read/write) are seated when the disk drive is parked.
7.
SECTOR : The sector number of each track
defined on the hard disk. (e.g.) The range is from “1” to “64”.
8.
MODE : Select “AUTO” to detect the
mode type automatically. If your hard disk supports the LBA mode, select
“LBA” or “LARGE”. However, if your hard disk cylinder is more
than 1024 and does not support the LBA function, you have to set at “ LARGE.”
Select “NORMAL” or “CHS” if your hard disk supporting cylinder is
below 1024.
· AUTO : This will auto-detect your IDE drive during boot-up. (auto detected on display during POST)
· Normal : For IDE hard disk drives which is smaller than 528MB.
·
LBA : For IDE hard disk drive which is above
528MB (ideally, it can be as big as 8.4GB) that use Logic Block Addressing
(LBA) mode.
·
Large : For IDE hard disk drive which is above
528MB and does not support LBA mode.
Notes
· “large mode” may not be fully supported by all operation systems. It is suggested to be used with the MS-DOS but such hard disk is not very popular nowadays.
· Some certain operating systems (such as SCO-UNIX™), only “Normal mode” is allowed when installation.)
Extra Note
· Many BIOS setups contain a hard drive auto detection utility; you can easily select the best values for your hard disk, automatically.
Floppy drive type
The category identifies the types of floppy disk drive A or drive B that have been installed in the computer.
Select your floppy drive size and correct formatted diskette capacity. Most systems can select two floppy drives, as drive A and B.
|
360KB, 5 ¼ In., |
5.25” PC- type 360KB capacity |
|
1.2MB, 5 ¼ in., |
5.25” AT- type 1.2MB capacity |
|
720KB, 3 ½ in., |
3.5” double- side 720KB capacity |
|
1.44MB, 3 ½ in., |
3.5” double- side 1.44MB capacity |
|
2.88MB, 3 ½ in., |
3.5” double- side 2.88MB capacity |
|
None
|
No floppy drive installed |
Video type
The category selects the type of video adapter used for the primary system monitor. Although secondary monitors are supported, you do not have to select the type in setup.
e.g. Choose Monochrome, Color 40x25,
VGA/EGA (default setting on most systems), Color 80x25
Floppy 3 Mode Support
This mode is for the Japanese 3.5 inch floppy disk drive. If you have such drive installed in your PC system, select “enable”, otherwise, use “disable”.
Halt On
The category determines whether the computer will stop if an error is detected during power up (POST).
All, But Keyboard - The system boot will not stop for a keyboard error, it will stop for all other errors
All, But Diskette - The system boot will not stop for a disk error, it will stop for all other errors
All, But Disk/Key - The system boot will not stop for a disk or keyboard error, it will stop for all other errors
All errors - When the BIOS detects a non-fatal error the system will be stopped and you will be prompted.
No errors - The system boot will not be stopped for any error that may be detected
Memory information
This category is display-only which is determined by POST of the BIOS.
Base Memory The value of the base memory is typically 512K or 640K based on the memory installed on the mainboard.
Extended Memory How much extended memory is present during the POST. This is the amount of memory located above 1MB in the CPU’s memory address map.
Other Memory This refers to the memory located in the 640K to 1024K address space. The BIOS is the most frequent user of this RAM area since this is where it shadows RAM
