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.
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
