<P>
<DL COMPACT>
<DT id="2"><B>BADYEAR</B><DD>
This is used to specify that the hardware clock is incapable of storing

broken or <B>no</B> if working correctly.
<P>
<DT id="3"><B>HWCLOCKACCESS</B><DD>
If the hardware clock is not accessible, set to <B>no</B>, in which
case hwclock will not be run. Otherwise, set to <B>yes</B>.
<P>
<DT id="4"><B>HWCLOCKPARS</B><DD>
Additional options for hwclock. Unset by default. For example, this
may be use to specify the machine hardware clock type for Alphas.
<P>
<DT id="5"><B>HCTOSYS_DEVICE</B><DD>
The hardware clock device you want to use. Defaults to <B>rtc0</B>.
It should probably match the CONFIG_RTC_HCTOSYS_DEVICE kernel config
option.
