C2SEA/C2SEE User’s Manual
Confi gure SATA#1 As
This feature allows the user to select the drive type for SATA#1. The options are
IDE and AHCI.
Primary IDE Channels Master/Slave, Secondary IDE Channels Maser/Slave
and Third IDE Channels Maser/Slave
These settings allow the user to set the parameters of Primary IDE Master/Slave,
Secondary IDE Master/Slave and Third IDE Master/Slave slots. Hit <Enter> to
activate the following submenu screen for detailed options of these items. Set the
correct confi gurations accordingly. The items included in the submenu are:
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 data to be transferred from and to the device one sector at
a time. Select Auto to allow 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.
