Hi all, you can now get an updated version of FDAPM from http://www.coli.uni-saarland.de/~eric/stuff/soft/fdapm-2007jan06.zip
Short description of the update: The new FDAPM version no longer hangs during flush / suspend / poweroff even if you have broken drivers or BIOS, and it supports more flexible ACPI handling, making poweroff and throttling (speed setting) work on more PCs. Thanks to ldwar lodoss and RayeR for asking for those extra compatibility additions and for testing them. NOTE: If FDAPM SPEED9 (check current speed, and show ACPI info) and other ACPI related functions crash for you, then you have to use the MEMCHECK option for EMM386. If you do not use EMM386, then you have to use another version of HIMEM, or none. Problem is that EMM386 and HIMEM can make access to ACPI data fail and throw an exception which FDAPM cannot catch and handle. Long explanation: See the HIMEM / EMM386 explanation above if FDAPM crashes for ACPI related functions... The update explicitly enables interrupts before it starts a delay: With broken drivers or BIOSes, FDAPM would otherwise get stuck in the few second delay of the FLUSH function. As FLUSH is also run for the STANDBY / SUSPEND / POWEROFF functions, those functions got stuck, too. The second change in the updated FDAPM is that now more complex ACPI data is supported, in particular having a Power Management 1b register set in addition to the basic 1a one, and having the ACPI table entry point in the extra BIOS area at e000:...., as opposed to the classic location at f000:.... or in the EBDA. The update fixes several issues: The ACPI tables on some modern HP PC are now found, poweroff / throttle will work on more chipsets, flush no longer hangs with RayeR's BIOS, and all people now get extra ACPI information by running FDAPM SPEED9 (read current speed) :-). Setting for example FDAPM SPEED2 is also a good way to make old games run better on new hardware AND save energy at the same time - Speed 2 means to halt the CPU 6/8 of all hardware timeslices :-). FDAPM is a tool for energy saving and related functionality in DOS. Most functions are direct action ones, only APMDOS stays in RAM: Put FDAPM APMDOS in your autoexec to halt the CPU and save energy whenever DOS is idle - in a safe way, so FDAPM should never degrade the speed of your DOS, but might not always give the best energy savings. Please read the documentation for more details about the other functions beyond POWEROFF, SPEEDn and APMDOS :-). Enjoy the new FDAPM version, and let me know if your hardware or software still causes problems. Eric ------------------------------------------------------------------------- Take Surveys.
