+
+ This driver has been tested in the following Linux kernels: v1.2.13,
+ v1.3.57, v2.0.30, v2.1.40. These kernel versions are major releases
+ of Linux or the latest Linux kernel versions available when this version
+ of the driver was released. The driver should also work in earlier
+ versions of the Linux kernel. Beginning with v1.3.58 the AdvanSys driver
+ is included with all Linux kernels. Please refer to sections C, D, and
+ E for instructions on adding or upgrading the AdvanSys driver.

In this source file the following constants can be defined. They are
defined in the source below. Both of these options are enabled by
default.
- 1. ADVANSYS_DEBUG - enable for debugging and assertions
+ 1. ADVANSYS_ASSERT - Enable driver assertions (Def: Enabled)
+
+ Enabling this option adds assertion logic statements to the
+ driver. If an assertion fails a message will be displayed to
+ the console, but the system will continue to operate. Any
+ assertions encountered should be reported to the person
+ responsible for the driver. Assertion statements may proactively
+ detect problems with the driver and facilitate fixing these
+ problems. Enabling assertions will add a small overhead to the
+ execution of the driver.
+
+ 2. ADVANSYS_DEBUG - Enable driver debugging (Def: Disabled)
+
+ Enabling this option adds tracing functions to the driver and
+ the ability to set a driver tracing level at boot time. This
+ option will also symbols not required outside the driver to
+ the kernel name space. This option is very useful for debugging
+ the driver, but it will add to the size of the driver execution
