2.Select USER and enter values into each drive parameter field.

3.Use the IDE HDD AUTO DECTECTION function in Setup. Here is a brief explanation of drive specifications:

Type :The BIOS contains a table of pre-defined drive types. Each defined drive type has a specified number of cylinders, number of heads, write precom- pensation factor, landing zone, and number of sectors. Drives whose specifications do not accommodate any pre-defined type are classified as type USER.

Size:Disk drive capacity (approximate). Note that this size is usually slightly greater than the size of a formatted disk given by a disk-checking program.

Cyls:Number of cylinders

Head: Number of heads

Precomp: Write precompensation cylinder

Landz: Landing zone

Sector: Number of sectors

Mode: Auto, Normal, large, or LBA

Auto

The BIOS automatically determines the optimal mode.

Normal

Maximum number of cylinders, heads, and sectors supported are 1024, 16, and 63.

Large

For drives that do not support LBA and have more than 1024 cylinders. Applicable to only a few drives.

LBA

Logical Block Addressing. During drive accesses, the IDE controller transforms the data address described by sector, head, and cylinder number into a physical block address, significantly improving data transfer rates. For drives with greater than 1024 cylinders.

Drive A, B

Select the correct specifications for the diskette drive(s) installed in the computer.

None : No diskette drive installed

360K : 5.25 in5-1/4 inch PC-type standard drive

Video Select the type of primary video subsystem in your computer. The BIOS usually detects the correct video type automatically. The BIOS supports a secondary video subsystem, but you do not select it in Setup.

Halt On During the power-on self-test (POST), the computer stops if the BIOS detects a hardware error. You can tell the BIOS to ignore certain errors during POST and continue the boot-up process. These are the selections:

No errors	POST does not stop for any errors.
All errors	If the BIOS detects any non-fatal error, POST stops and prompts
	you to take corrective action.
All, But Keyboard	POST does not stop for a keyboard error, but stops for all other
	errors.
All, But Diskette	POST does not stop for diskette drive errors, but stops for all other
	errors.
All, But Disk/Key	POST does not stop for a keyboard or disk error, but stops for all
	other errors.
