0,0 → 1,47
2001-07-27 Jesper Skov <jskov@redhat.com>
 
* src/ds12887.cxx (init_ds_hwclock): Use BCD mode since Century is
NA in binary mode. Force sane settings in registers if they are
undefined.
 
2001-07-06 Jesper Skov <jskov@redhat.com>
 
* src/ds12887.cxx (get_ds_hwclock): Instead of locking while
reading (which prevents updates if polled), disable interrupts.
 
* New package, based on 1742 driver.
