Chapter 7: BIOS

7-5

Type

Select the type of device connected to the system. The options are Not Installed,

Auto, CDROM and ARMD.

LBA/Large Mode

LBA (Logical Block Addressing) is a method of addressing data on a disk drive.

In the LBA mode, the maximum drive capacity is 137 GB. For drive capacities

over 137 GB, your system must be equipped with a 48-bit LBA mode addressing.

If not, contact your manufacturer or install an ATA/133 IDE controller card that

supports 48-bit LBA mode. The options are Disabled and Auto.

Block (Multi-Sector Transfer)

Block Mode boosts the IDE drive performance by increasing the amount of data

transferred. Only 512 bytes of data can be transferred per interrupt if Block Mode

is not used. Block Mode allows transfers of up to 64 KB per interrupt. Select

"Disabled" to allow the data to be transferred from and to the device one sec-

tor at a time. Select "Auto" to allows the data transfer from and to the device

occur multiple sectors at a time if the device supports it. The options are Auto

and Disabled.

PIO Mode

The IDE PIO (Programmable I/O) Mode programs timing cycles between the

IDE drive and the programmable IDE controller. As the PIO mode increases, the

cycle time decreases. The options are Auto, 0, 1, 2, 3, and 4. Select Auto to

allow the AMI BIOS to automatically detect the PIO mode. Use this value if the

IDE disk drive support cannot be determined. Select 0 to allow the AMI BIOS

to use PIO mode 0. It has a data transfer rate of 3.3 MBs. Select 1 to allow the

AMI BIOS to use PIO mode 1. It has a data transfer rate of 5.2 MBs. Select 2 to

allow the AMI BIOS to use PIO mode 2. It has a data transfer rate of 8.3 MBs.

Select 3 to allow the AMI BIOS to use PIO mode 3. It has a data transfer rate

of 11.1 MBs. Select 4 to allow the AMI BIOS to use PIO mode 4. It has a data

transfer rate of 16.6 MBs. This setting generally works with all hard disk drives

manufactured after 1999. For other disk drives, such as IDE CD-ROM drives,

check the specifi cations of the drive.

S.M.A.R.T. For Hard disk drives

Self-Monitoring Analysis and Reporting Technology (SMART) can help predict

impending drive failures. Select "Auto" to allow the AMI BIOS to auto detect

hard disk drive support. Select "Disabled" to prevent the AMI BIOS from using

the S.M.A.R.T. Select "Enabled" to allow the AMI BIOS to use the S.M.A.R.T. to

support hard drive disk. The options are Disabled, Enabled, and Auto.
