EIDE Interfaces
The two EIDE interfaces support PIO mode 4 with transfers up to 14 MB per second and

sustain a maximum transfer rate of 33 MB per second between the EIDE drive buffer
and PCI.
There are two independent EIDE ports available (a primary onboard and a secondary
on the Rear I/O). The primary EIDE interface is a 40-pin, 2-row male connector AT

Each EIDE interface provides support for two devices (one master and one slave). All
HardDisks can be used in cylinder head sector (CHS) mode with the BIOS also
supporting the logical block addressing (LBA) mode.
