Marvell Serial ATA BIOS extension driver
----------------------------------------

Introduction 
------------
The BIOS extension driver is a driver firmware that it's main task is to enable
PC compatible systems to boot operating systems.

The operating systems can be Windows 2000, Linux or DOS or others ...

The driver firmware is usually loaded into the adapter's, and the BIOS in POST
can load the driver firmware into system memory and thus enabling the boot.

Another alternative for mother board vendors, is integrating the driver's
firmware into main BIOS.


Using the BIOS extension driver
-------------------------------
There are mainly two kinds of BIOS version ; PnP BIOS and non-PnP BIOS.

While booting from PnP BIOS or non-PnP BIOS, the BIOS extension driver will
be executed by the BIOS and proper messages on the monitor will show the
version of the BIOS extension driver and the hard drives detected on the
serial ATA channels.

While using PnP BIOS, the user will have the ability to select the hard drive
to boot from using the BIOS specific menus (depends on the BIOS vendor).

While using a non-PnP BIOS the first hard drive detected in the system will be
bootable.


Building the BIOS extension driver
----------------------------------
1.. Download and install Watcom C compiler version 1.0 on a Windows 2K machine
    on C:\watcom directory (default). The installation should be an
    installation for 16bit dos / 32bit dos / 16bit Windows / 32bit Windows
    targets.
    (http://www.openwatcom.org/)
2.. Unzip the release into any directory.
3.. Open command line and change the directory to the release directory.
4.. Change the directory back again to the BiosIAL directory.
5.. From the command line, run the makeBiosDriver.bat

The compiled images are -
1.. The driver itself  (under driver/biosimage.com).
2.. tools/generateImage/generateImage.exe application - This tool takes
    the biosimage.com as the basic image and adds to it all the PCI expansion
    ROM headers with the required checksums and produces a raw binary image
    that can be loaded into flash.
3.. mvFlshUp.com - A utility that can be run under DOS for loading a specific
    ROM image to an adapter. Note that this tool does matching between the PCI
    expansion ROM headers and the device ID of the required adapter.

Loading and Updating BIOS extension driver on Marvel Serial ATA adapter
-----------------------------------------------------------------------
1.. Boot the system with DOS version 3.3 or higher.
2.. Put the mvFlshUp.com and the required image on diskette. For example, if
    the adapter is 88SX6081 then the required image is 6081.IMG.
3.. Put the diskette on floppy A and execute 'mvFlshUp 6081.IMG' in case
    the required adapter is 88sx6081.
4.. The mvFlashUp utility will scan all PCI devices with the corresponding
    device ID (in the previous example, it will scan 88SX6081 adapters) and
    prints a list with the adapters with the version numbers installed
    on it (if any).
5.. Follow the instructions and choose the required adapter.
