ruthan Posted August 28, 2017 Share Posted August 28, 2017 Im trying to something on old installation (installed with ACPI), but system devices often collide with ACPI Embedded somehing, ACPI Bios.. and ACPI IRQ something mutipletimes, but these devices are found only after Add new HW Wizard search, otherwise after System device removal and PCI bus addition they are not there.. but add new hw wizzard also find usefull devices after search.. and there are probably other ACPI related issues.

rloew Posted August 29, 2017 Share Posted August 29, 2017 Delete/rename ACPI.SYS. Reboot. Install "PCI Bus" if needed. Link to comment Share on other sites More sharing options...
ruthan Posted August 29, 2017 Author Share Posted August 29, 2017 (edited) Thanks i will test it, expected that there would something like Registry key for it, i tried myself through ACPI.sys file deletion and try to avoid to installation of ACPI related drivers, but i wrote HW detection wizard is still forcing it and driver were autoimported from SP3.cab.

Go to HKLM\Software\Microsoft\Windows\CurrentVersion\Detect and add as a dword value ACPIOption=2. Close regedit and redetect your hardware: windows will remove all ACPI related devices from the system and add APM. Link to comment Share on other sites More sharing options...
ruthan Posted August 29, 2017 Author Share Posted August 29, 2017 Ok and what about shutdown? Its still possible without ACPI, make Widnows 98 ATX shutdown working? ATX shutdown in mean shutdown without press shutdown button, only through SW. Link to comment Share on other sites More sharing options...
dencorso Posted August 29, 2017 Share Posted August 29, 2017 Yes. APM does that too. Link to comment Share on other sites More sharing options...
rloew Posted August 30, 2017 Share Posted August 30, 2017 If you don't remove the ACPI Device from Device Manager, it will not reinstall ACPI.SYS, it will just fail. SP3.CAB is part of U98SESP3, not part of Windows 9x. This is not Windows XP. Link to comment Share on other sites More sharing options...
ruthan Posted August 31, 2017 Author Share Posted August 31, 2017 Quote Yes. APM does that too. How to check that APM is there + is working? I have know lots of installation, where automatic shutdown is not working. Link to comment Share on other sites More sharing options...
dencorso Posted August 31, 2017 Share Posted August 31, 2017 But to true DOS (not a DOS Box) and run the attached program. If APM exists it'll shut down. Else it'll just give you a message but DOS will keep running. APMOFF.7z Link to comment Share on other sites More sharing options...

dencorso Posted September 1, 2017 Share Posted September 1, 2017 Both. You can setup windows to ignore both APM and ACPI. But if the motherboard has just ACPI, there's no way to use APM (newer motherboards may not have APM) and if the motherboard has just APM, there's no way to use ACPI. If the board has both, one may use either or none. Link to comment Share on other sites More sharing options...
ruthan Posted September 1, 2017 Author Share Posted September 1, 2017 (edited) Ok i tested my Asus AMD970SB AM3 board and APM is not present, so no shutdown at all, or there is change through some Bios settings?
