1.0  Overview
_____________

This package includes the NDIS2 DOS/OS2 drivers version 1.19 for
NDIS2 DOS / OS2 support for all IBM Broadcom 570x-based Gigabit
Ethernet, including 22P7801 adapter option.

NDIS2 DOS and OS2 are supported.

This package is created by PackageForTheWeb, which allows users
to be able to extract all files and directories into either the
default destination provided or any drive destination the users
wish to specify.


2.0   Limitations
_________________

This driver does not share IRQs correctly.  Use the system BIOS
configuration utility to ensure that the Broadcom adapter has a
unique IRQ assignment.

10/17/02 - v1.19
        Fixed problem with forced LineSpeed and Duplex.

10/16/02 - v1.18
        Fixed problem with ASF enabled.

10/16/02 - v1.17
        Fixed problem with system appeared to hang when cable was removed.

08/13/02 - v1.14-
        Fixed problem with EMM386.
        Used PXE's LM.
        Clean out NIC's Status Block during initialization to prevent spur-interrupt after
        initialization.
        Slim down Host memory used by adpater (dropped 48K memory foot print).

07/25/02 - v1.13-
        Hanle Transmit Segment equal to 0 for OS2 Granite trap.

07/12/02 - v1.12-
        Fixed problem with the RPL boot up, the driver hangs while downloading file image.
        The Boot Block Configuration file *.cnf MUST specify in the DRV Type's second field
        the additional memory (53KB-60KB) used by the driver as follows:

         DRV BBLOCK\NDIS\B57.DOS ~ 53 ~

        Block re-entrance during Interrupt handler loop in OS2 driver.
        Hanle Transmit Segment equal to 0 for OS2 Granite trap-this does not work.

        Fixed a low performance problem with BCM5701 Serdes LOMs with Copper Trace
        media. As in the PXE v2.1.2.

        Port number correction.

4.0   Installation and Configuration

CUSTOM KEYWORDS for the driver in protocol.ini:

BUSNUM
DEVNUM
FUNCNUM or PORTNUM

The first two keywords are used concurrently and have been included
for manufacturing purposes.  Do not use them unless you are familiar
with PCI device configuration.
These two keywords are needed if multiple NetXtreme boards are on a
system and (a) specific NetXtreme adapter/s need to be loaded in
specific order.  BUSNUM specifies the PCI bus number and DEVNUM
specifies the device number given to the board when configured by the
PCI BIOS.  A PCI device scan utility is needed to find this info.
The values are in decimal.

Example of the use of these key words in the protocol.ini:

[B57]
    DriverName = "B57$"
    BusNum = 3
    DevNum = 14
    PortNum = 2

To add more adapter(up to 4) repeat the below entry, where n can be
from 1 to 3.

[B57_n]
    DriverName = "B57$"
    BusNum =
    DevNum =

Example of using addition entries to load more than one adapter in
the protocol.ini:

[B57]
    DriverName = "B57$"
    BusNum = 3
    DevNum = 10

[B57_1]
    DriverName = "B57$"
    BusNum = 3
    DevNum = 11

[B57_2]
    DriverName = "B57$"
    BusNum = 3
    DevNum = 12

[B57_3]
    DriverName = "B57$"
    BusNum = 3
    DevNum = 13


NOTE: For RPL boot up, the Boot Block Configuration file *.cnf MUST
  specify in the DRV Type's second field the additional memory
  (53KB-60KB) used by the driver as follows:

      DRV BBLOCK\NDIS\B57.DOS ~ 53 ~
