IDE port Connector: CN4 / CN6

This product provides a bus-mastering PCI IDE interface. This interface support PIO Mode 3, PIO Mode
4, ATAPI devices (e.g., CD-ROM), and Ultra DMA/33/66/100 synchronous-DMA mode transfers. The
BIOS supports logical block addressing (LBA) and extended cylinder head sector (ECHS) translation
modes. The BIOS automatically detects the IDE device transfer rate and translation mode.
This connector supports the provided IDE hard disk ribbon cable. After connecting the single end to the
board, connect the two plugs at the other end to your hard disk(s). If you install two hard disks, you must
configure the second drive to Slave mode by setting its jumper accordingly. Please refer to your hard
disk documentation for the jumper setting.
CAUTION
- IDE secondary port cannot support by UltlaDMA66/100 mode at the time of CF card use.
- IDE secondary port can support one drive at the time of CF card use.
