PC87410 PCI-IDE Interface Controller
General Description
The PCI-IDE Interface Controller is designed to interface the
IDE drive directly onto the PCI bus It provides write posting
and read pre-fetches allowing the CPU to run concurrently
with IDE cycles It connects IDE drIves ‘‘gluelessly’’ into the
PCI bus and supports faster ATA devices using modes 1 2
and 3 through PIO accesses It supports dual IDE channels
for up to four drives and works seamlessly with the National
Semiconductor’s SuperI O^TM family of products
A full suite of software drives included with device are fully
tested with DOS 5 0–6 x Windows 3 x–4 x Windows NT
OS 2 2 x Novell Netware 3 1x–4 x and SCO UNIX 3 x
