**82380FB/AB PCIset: 82380FB Mobile PCI-to-PCI Bridge(MPCI2) 02/17/97
***Notes:...
***Info:
The Intel 380FB PCIset (380FB) consists of the 82380FB Mobile
PCI-to-PCI Bridge (MPCI2) and the 82380AB Mobile PCI-to-ISA Bridge
(MISA). The 380FB supports four PCI slots and three ISA slots. The
MPCI2 and MISA can also be used individually to provide either PCI
slot expansion or ISA slot expansion.
The 380FB supports a full Hot Docking capable docking station with 5V
PCI and ISA add-in expansion slots. MPCI2 provides the docking con-
trol for hot insertion, power management, and a PCI-to-PCI bridge to a
5V PCI desktop style add-in bus. Internal arbitration supports four
bus masters on the secondary PCI bus. The PC/PCI arbitration interface
logic provides PC/PCI bridge support. The 380FB controls all docking,
undocking and suspend/resume sequences for the docking station. The
EPROM interface logic provides an industry standard interface to a
non-volatile memory device (EPROM) for supporting dynamic
autoconfiguration of a previously configured notebook/docking station
combination. The Power management logic provides a control and status
interface between the docking station and notebook that allows the
docking station to control the state of the notebook. A non-volatile
memory interface is used to store docking identification and notebook
configuration information to speed dynamic configuration for a
pre-configured notebook docking combination.
MPCI2 supports the PCI bus enumeration mechanism for PCI-to-PCI
bridges. This is needed to support the Windows 95 dynamic
configuration of system resources when the system docks or
undocks. Otherwise, the operating system must reset the system after
reconfiguration. The undocking mechanism of the 380FB guarantees a
safe notebook removal. Event notification allows docking resources to
be dynamically removed and applications gracefully shut down, if
needed. A hardware mechanism is provided to indicate when the notebook
is prepared to undock. This can be used to eject or unlock the
notebook from the docking station.
The MPCI2’s subtractive decoding guarantees that all accesses targeted
for a downstream ISA bridge (such as the MISA) arrive at their
destination. Software does not need to determine the devices on the
ISA bridge and then program positive decode ranges (as is needed on
traditional positive decode bridges).
