IDE port Connector: IDE1
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.
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.
