Support and Compatibility Disclaimers
Since drivers function at the kernel level, Hewlett-Packard Company (HP) reminds you of the following:
Adding your own driver to HP-UX requires relinking the driver into HP-UX. With each new release, plan on
recompiling the driver and reinstalling it in the new HP-UX kernel. Many header files do not change.
However, drivers typically use some header files that could change across releases (that is, you can have some
system dependencies).
HP provides support services for HP products, including HP-UX. Products, including drivers, from non-HP
parties receive no support, other than the support of those parts of a driver that rely on the documented
behavior of supported HP products.
If difficulties arise during the development and test phases of writing a driver, HP may provide assistance in
isolating problems to determine if:
• HP hardware is not at fault; and
• HP software and firmware is not at fault by removing user-written kernel drivers.
