IDE Connector: CN7/ CN8

CN8: Secondary IDE Connector
The CPU card SPI-8450-LLVA provides a bus-mastering PCI IDE interfaces. These
interfaces 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.
These connectors support 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.
