Enhanced IDE Interface 
The ICH6’s IDE interface handles the exchange of information between the processor and 
peripheral devices like hard disks, CD-ROM drives, and Iomega Zip
*
 drives inside the computer.  
The interface supports: 
•  Up to two IDE devices (such as hard drives) 
•  ATAPI-style devices (such as CD-ROM drives) 
•  Older PIO Mode devices 
•  Ultra DMA-33 and ATA-66/100 protocols 
•  Laser Servo (LS-120) drives 
Serial ATA  
The desktop board supports four Serial ATA channels via ICH6, connecting one device per 
channel. 
Expandability 
The desktop board supports the following:  
•  One PCI Express x1 add-in card  
•  Two PCI add-in cards 
BIOS 
The BIOS provides the Power-On Self-Test (POST), the BIOS Setup program, the PCI/PCI 
Express and IDE auto-configuration utilities, and the video BIOS.  The BIOS is stored in the 
Firmware Hub. 
Serial ATA and IDE Auto Configuration 
If you install a Serial ATA or IDE device (such as a hard drive) in your computer, the auto-
configuration utility in the BIOS automatically detects and configures the device for your computer.  
You do not need to run the BIOS Setup program after installing a Serial ATA or IDE device.  You 
can override the auto-configuration options by specifying manual configuration in the BIOS Setup 
program. 
PCI and PCI Express Auto Configuration 
If you install a PCI/PCI Express add-in card in your computer, the PCI/PCI Express auto-
configuration utility in the BIOS automatically detects and configures the resources (IRQs, DMA 
channels, and I/O space) for that add-in card.  You do not need to run the BIOS Setup program after 
you install a PCI/PCI Express add-in card.
