$Id: HISTORY,v 1.43 2004/07/21 12:03:54 bistr-o-math Exp $
+ denotes a new feature
* denotes a bugfix/some change
- denotes a removed feature
2004-07-21: Version 0.97 (beta)
+ Added support for upper nvram on boards with VIA's VT8233 south bridges.
+ Added two new configuration file options: chk_method and day_no_bcd
(see 'man nvram-wakeup.conf' for more information)
+ Added man pages for all helper programs and scripts.
* Renamed guess-helper.sh to guess-helper.
* Fixed a minor bug in the time helper command.
+ Added several new mainboards. See CVS logs for details and credits.
Thanks to everyone who sent me his/her board configuration.
2004-05-22: Version 0.96 (beta)
+ Added support for upper nvram on boards with VIA's VT8235/37 south bridges.
+ Added support for upper nvram on boards with nVidia nForce2 chipset.
+ Added support for upper nvram on boards with ATI RADEON 9100 IGP chipset.
+ Added several new mainboards. See CVS logs for details and credits.
Thanks to everyone who sent me his/her board configuration.
+ Added a few more examples to be used by hand in the man page.
2004-04-06: Version 0.95a (beta)
* two small bugs in guess and guess-helper were fixed.
+ Added several new mainboards. See CVS logs for details and credits.
Thanks to everyone who sent me his/her board configuration.
2004-02-29: Version 0.95 (beta) "Feb 29th - release"
* IMPORTANT: the various _date fields changed to _day. _date configuration
options are accepted but will be removed in one of the next versions.
* IMPORTANT: need_reboot=ALWAYS was changed to need_reboot=ON_ANY_CHANGE since
it produced some confusion on the meaning. The value ALWAYS is still accepted
but will be removed in one of the next versions.
+ Added a new option --directisa. This is an alternative for using /dev/nvram
See man page for more information.
+ Added support for upper nvram on boards with Intel's ICH* south bridges,
VIA's VT82C686A, VT82C686B, VT82C596 and south bridges with Dallas
Semiconductor's DS1685/1687.
+ Added a LOT of new mainboards and updated/added a LOT of new autodetection strings.
See CVS logs for details and credits.
Thanks to everyone who sent me his/her board configuration.
+ Added guess-helper script (by Tobias Grimm), see README.mb for more details.
2003-08-07: Version 0.91 (beta)
* IMPORTANT: the option --iwstring is now called --iwname.
* Changed `guess' to produce output in configuration file format.
+ Added a LOT of new mainboards and updated/added a LOT of new autodetection strings.
See CVS logs for details and credits.
Thanks to everyone who sent me his/her board configuration.
* Updated man pages, preventing triggering a bug in troff 1.17.2
+ Added some debug output here and there
* The vdrshutdown script now supports checks for non-shotdown-conditions like
- users are logged in
- some process (like movie conversion) is running
- whatever else.
This conditions are freely configurable. look into the script vdrshutdown for more info.
* the reboot images and patches are moved to a separate "package" -- just a tar file
2003-03-04: Version 0.90 (beta) "Birthday release"
+ Added support for configuration files. (option -C|--configfile)
+ Added a manual page for the configuration file.
+ Added support for mainboard autodetection
(contributed by Bernhard "Bero" Rosenkraenzer <bero@arklinux.org>)
this feature uses code from the dmidecode program (https://savannah.nongnu.org/projects/dmidecode/)
- got rid of ACTUALLY_WRITE
+ now write by default. A new option (-N/--nowrite) emulates the old ACTUALLY_WRITE=OFF
behaviour.
2003-03-04: Version 0.05 (stable) "Birthday release"
+ Added several new mainboards. See nvram-wakeup-mb.h for details and credits.
Thanks to everyone who sent me his/her board configuration.
2002-04-14: Version 0.04b (beta)
+ Added several new mainboards. See nvram-wakeup-mb.h for details and credits.
Thanks to everyone who sent me his/her board configuration.
+ Added a new configuration option ADDR_WDAYS to nvram-wakeup-mb.h.
It seems that there are boards storing the weekday instead of a date.
* Now really fixed the problem with the daylight savings.
(I should have read ftp://ftp.gnu.org/pub/gnu/Manuals/glibc/pdf/libc.pdf
earlier)
2002-04-03: Version 0.04a (beta)
* Fixed the problem with the daylight savings.
* Some mainboard updates. See nvram-wakeup-mb.h for details and credits.
Thanks to everyone who sent me his/her board configuration.
2002-03-24: Version 0.04 (beta)
* IMPORTANT: It turned out that not only the MSI boards need to be rebooted
after making a change, but also some other boards in special cases. Therefore
the exit states are changed. Now we have:
0 - successful, everything is set properly. don't need to reboot.
1 - successful, everything is set properly. must reboot the changes to take effect.
2 - error occurred. something went wrong.
the script vdrshutdown is changed accordingly, but if you're using your own script,
you have to look at it.
* Completely rewritten many parts of the main program.
+ We can handle the case now where more than one information (e.g. date
and status) is stored in the same byte at different bits.
+ Started using debug mode for printing debug messages.
* Added/Removed/Changed several options in nvram-wakeup-mb.h and added a more
detailed documentation of them at the beginning of the file.
(See into nvram-wakeup-mb.h for more information.)
+ Added some more intelligence to `guess'.
(still consider `guess' alpha quality)
+ Added a new rule `devices' to Makefile.
It creates /dev/nvram and /dev/rtc if they are missing.
+ Print rtc time before setting it. (was just forgotten in ver. 0.03)
+ Added several new mainboards. See nvram-wakeup-mb.h for details and credits.
Thanks to everyone who sent me his/her board configuration.
+ Added support for storing month.
(only for the boards with a BIOS which supports it)
* Replaced RUN_BEFORE by NEED_TO_SHTDWN, which has a slightly different
meaning (see README or nvram-wakeup.h for more details).
+ Added a new rule to Makefile: install.
(The user has to adjust paths in Makefile before installing)
* /dev/nvram and /dev/rtc are never opened at the same time now,
(this prevented some machines from halting by `halt -p')
Thanks to Dr. Werner Fink <werner@suse.de> for the hint.
* Don't need write permissions for /dev/nvram if no -s/-d parameter was specified
or ACTUALLY_WRITE==OFF
2002-02-04: BUGFIX
* Fixed the BCD bug introduced in Version 0.03
2002-02-01: Version 0.03 (beta)
* Moved the ACTUALLY_WRITE from nvram-wakeup.h to Makefile
+ Added a bunch of new boards. See nvram-wakeup-mb.h for details and credits.
Thanks to everyone who sent me his/her board configuration.
+ Added new mb parameters NEED_RTC, RESET_DATE, BCD
+ Adapted nvram-wakeup to use the BCD notation used on some boards.
+ README.mb is a new document containing information about how to figure
out the addresses of the stored values.
+ Autodetecting if CMOS clock runs at GMT or local time.
Thanks to Dr. Werner Fink <werner@suse.de>
* Now we require both nvram and rtc drivers (we need the latter one for
detecting if the rtc clock is running in localtime or UTC/GMT)
+ Added a new command line option: -D (--debug).
It enables printing of debug messages. (not many of them now)
+ New command line option -l (--syslog) to pass all output to syslog.
+ The vdrshutdown script now makes use of the new -l (--syslog) command line
option.
+ Introduced the variable RUN_BEFORE to use instead of 2*WAKEUP_BEFORE
in several places. Now the two things are independant.
+ Now I tested boot.diff on a SuSE 7.2 system.
+ If there wouldn't be changed anything in nvram, don't write into it.
* Now the exit status is always one of the following:
0 - Successfully finished
1 - We had to set (disable/enable) the wakeup date and time, but they were
already set to proper values. We didn't write them again.
2 - Some error occurred.
+ Modified the script vdrshutdown to take advantage of the new exit status of
nvram-wakeup. Especially useful on MSI MS-6351, where you have to reboot
after changing nvram.
+ Added a new program `guess', which should help to retrieve the addresses in
nvram guessing them from four given states. Consider this program to be
alpha quality.
+ Added a new program `rtc', the only thing it does: It prints the currently
set RTC alarm time.
+ Added a man page and a new `man' rule in the Makefile
+ Added a HISTORY file (actually, you are reading it at the moment).
2001-10-17: Version 0.02 (never released).
+ Added support for clocks running in UTC/GMT time.
+ Added some new motherboards.
* rewritten calculate_read and calculate_write to be more human readable
Thanks to Leiser <gregorski@leisergmbh.de> for the idea.
2001-10-10: Version 0.01 (Initial revision).
+ Could read/write wakeup time via /dev/nvram.
+ Predefined configurations for two motherboards: MSI MS-6351 and Biostar M6VCG
+ Accepts command line options -s (--settime), -d (--disable), -h (--help),
-v (--version).
2001-08-17: The idea was born
+ There was a discussion on the linux-dvb mailinglist about ways to poweron
a PC automatically.
+ The message by Frank Klingenhoefer <frank.private@t-online.de>:
http://linuxtv.org/mailinglists/linux-dvb/2001/08-2001/msg00457.html
(and a following off-list discussion with him and Hans-Hermann Redenius
<redenius@uni-oldenburg.de>) gave me the idea to write some small program
for setting the Wakeup feature.
