Yes, but it sure would be nice to insist that BIOS reconfiguration
programs are present when BIOS-specific information is available in the
architecture.

Accessibility(TETIAC) - from within Windows- HP solution

Hi Allen, guys,

Please remember that the BIOS issues we are discussing are an
implementation detail of x86 PC-based systems. There is no exposed BIOS
user-interface for almost every other computing architecture and device.

Not on Macintosh, not on SPARC, not on cell phones, not on copiers, not
on MP3 players.

The exposed BIOS user interface is a program running in a limited
environment - there is no OS yet, there is no platform-defined set of
themes or color/contrast, etc.

I believe strongly that it would be wrong for us to write BIOS
recommendations in TEITAC.

We should treat the user interaction functionality provided by BIOS
configuration programs as we would anything else. If the system is a
"closed" system at the time the BIOS is running (no way to run AT), then
those provisions should apply. If there are no system-define color and
contrast settings that the BIOS config UI can draw from, then we have
other rules that apply. Etc.

We can also ask the question of whether BIOS re-configuration that one
can do from a running system (as we're seeing are available from laptops
from HP, Dell, and Lenovo) is sufficient. Since making changes to these
settings during the boot process is something you only *have* to do at
that time when the system is failing to boot, I suggest that the "fix a
system when it is broken" situation is largely outside of the scope of
most of the 508 technical standards. Based on that, I suggest that BIOS
re-configuration programs that you can use on a running system should
suffice, so long as they are of course accessible.
