Drive Parameters

The “grayed-out” items in the left frame are the IDE disk drive parameters taken from the firm-

ware of the IDE disk drive selected. The drive parameters listed are as follows:

Type

Optimal and Fail-Safe default settings: Auto

PARAMETER DESCRIPTION

Device Type of device, such as hard disk drive.

Vendor Manufacturer of the device.

Size The size of the device.

LBA Mode LBA (Logical Block Addressing) is a method of addressing data on a disk drive. The CP305

supports 48-bit LBA mode. Thus, hard disks with a drive capacity of greater than 137 GB

and can be used on the CP305.

Block Mode Block mode boosts 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.

PIO Mode IDE PIO mode programs timing cycles between the IDE drive and the programmable IDE

controller. As the PIO mode increases, the cycle time decreases.

Async DMA This indicates the highest Asynchronous DMA Mode that is supported.

Ultra DMA This indicates the highest Synchronous DMA Mode that is supported.

S.M.A.R.T. Self-Monitoring Analysis and Reporting Technology protocol used by IDE drives of some

manufacturers to predict drive failures.

SETTING DESCRIPTION

Not Installed Use this setting to prevent the BIOS from searching for an IDE disk drive on the specified

channel.

Auto Use this setting to allow the BIOS to auto detect the IDE disk drive type attached to the

specified channel. This setting should be used if an IDE hard disk drive is attached to the

specified channel.

CD/DVD Use this setting to specify that an IDE CD-ROM drive is attached to the specified IDE chan-

nel. The BIOS will not attempt to search for other types of IDE disk drives on the specified

channel.

ARMD Use this setting to specify an ATAPI Removable Media Device.

This includes, but is not limited to:

• ZIP

• LS-120
