2.3 Primary IDE port Connector: CN10
The CPU card SIS-8601-LVA has one independent 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.
Programmed I/O operations usually require a substantial amount of processor
bandwidth. However, in multitasking operating systems, the bandwidth freed by bus mastering
IDE can be devoted to other tasks while disk transfers are occurring.
This connector support the provided IDE hard disk ribbon cable. After connecting
the single end to the board connector, 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.
