2.12 IDE port Connector: CN11 / CN13

CN11:Primary IDE connector CN13:Secondary IDE connector
The CPU card SPI-8150-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.
