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 AMC
module supports 48-bit LBA mode. Thus, hard disks with a drive capacity greater than 137
GB can be used on the AMC module.
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 permit 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.
CDROM
Use this setting to specify that an IDE CD-ROM drive is attached to the specified IDE chan-
nel.
In this case, 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
