Standard CMOS Setup

Hard Disk

Primary Master/Primary Slave/Secondary Master/Secondary Slave

The categories identify the types of 2 channels that have been installed in the computer. There are 45 predefined types and 4 user definable types are used for Enhanced IDE BIOS. Type 1 to Type 45 are predefined. Type "User" is user-definable. If your hard disk drive type is not listed in the 45 predefined types, you can use type "User" to define your own drive type manually.

If you select type "Auto", the system will autodetect your hard disk at boot up. If you select type "User", related information is asked to be entered to the following items. Enter the information directly from the keyboard and press Enter:

If the controller of the HDD interface is ESDI, the type should be set to "1".
If the controller of the HDD interface is SCSI, the type should be set to "None".
If the controller of the HDD interface is CD-ROM, the type should be set to "None".

Settings

CYLS	Enter the number of cylinders
HEAD	Enter the number of heads
PRECOMP	Enter Write precompensation value
LANDZ	Enter Landing Zone sector
SECTOR	Enter the number of sectors
MODE	Normal,Large or LBA

Write Precom:

(Write Precompensation) Older hard drives have the same number of sectors per track at the innermost tracks as at the outermost tracks. This means that the data density at the innermost tracks is higher and thus the bits are lying closer together. Starting with this Cylinder until the end of Cylinders the writing starts earlier on the disk. In modern HDs this entry is useless. Set it either to -1 or max Cyln (a common value is 65535). For IDE (Integrated Device Electronics) hard drives it is not necessary to enter a WP cylinder. The IDE HDD will ignore it for it has its own parameters inboard.

Landing Zone:

The address of the landing zone. Used in old HDs without an auto-parking feature, or RLL. Set it to 0 or max Cylinder.

Mode:

Normal: Use the old IDE specification mode (drives up to 528 megabytes)
Large: Not used very often, use LBA instead. (For drives that do not support LBA and have more than 1024 cylinders.)
LBA: (Logic Block Addressing): mode which considers logic blocks instead of heads, cylinders and sectors. (for drives >528MB). If your BIOS does not support LBA, several hard disk manufacturers provide drivers to trick the BIOS.

Video

You have two ways to boot up the system:

When VGA used as primary and monochrome used as secondar, the selection of the vido type is "VGA Mode".

When monochrome uses as primary and VGA used as secondary, the selection of the video type is "Monochrome Mode"

Settings

EGA/VGA	Enhanced Graphics Adapter/Video Graphic Array. For EGA, VGA, SEGA or PGA monitor adapters.
CGA 40	Color Graphic Adapter, power up in 40 column mode.
CGA 80	Color Graphic Adapter, power up in 80 column mode.
MONO	Monochrome adapter includes high resolution monochrome adapters.

Error Halt

This category determines whether the computer will stop if an error is detected during power up.

Settings

No errors	The system boot will not be stopped for any error that may be detected.
All errors	Whenever the BIOS detects a non-fatal error, the system will be stopped and you will be prompted.
All, but keyboard	The system boot will not stop for a keyboard error, but it will stop for all oherse.
All, but disk	The system boot will not stop for a disk error, but it will stop for all ohers
All, but disk/keyb	The system boot will not stop for a keyboard or disk error, but it will stop for all ohers

Memory

This category is display-only. The contents are determined by the POST (Power On Self Test) of the BIOS.

Settings

Base Memory	The POST of the BIOS will determine the amount of base (or conventional) memory installed in the system.
Extended Memory	The POST of the BIOS will determine the amount of extended memory installed in the system.
Other Memory	This is memory that can be used for different applications. Most use for this area is Shadow RAM.
Total Memory	The total memory is the sum of Base, Extended and other memory.
