possible, ur 98 system is installed in ACPI mode. but for work my ACPIOFF pack req that system was installed NOT in ACPI mode. try reinstall 98 with "/p i" switch.

Before reinstalling, what *IS* the system you're running 98SE on? Maker, model and processor specs, please.

MERCURY127: if i don't install the Windows 98 with "/p i" switch, i will get installer errors and can't find the devices and drivers.

dencorso: i installed windows 98 SE and then i update, just the theme, to ME.. version 4.10.2222 A

CER Aspire 1690

CPU: Intel Pentium M 730 processor 1.60GHz

Graphics:  ATI Mobility Radeon X600 of 64MB's VRAM

RAM: 512MB's

try set Bootlogo=0 and Bootgui=0 in msdos.sys, reboot machine, run my patched win.com manually

C:\>WIN<Enter>

and test acpioff again...

problem not resolved

my ACER or BIOS is prepared for turn off automatic?

 

Here. extract the attached .7z and try set Bootlogo=0 and Bootgui=0 in msdos.sys, reboot machine and run 
C:\APMOFF<Enter>

It'll either turn the machine of or give you a message.

Report what happens, please.

APMOFF.7z

after trying several times... the NTKERN.VXD, MMDEVLDR.VXD device loader's are damage or something, because the device can't load them

get fdapm from here https://www.ibiblio.org/pub/micro/pc-stuff/freedos/files/distributions/1.2/repos/pkg-html/fdapm.html
unpack to c:\, then boot to pure dos mode (w/o gui) and run next command:

C:\>FDAPM POWEROFF

machine should turn off... if no - then u have BIG problem with legacy apm/acpi implementation in ur BIOS...

sorry, i forget - no Bootlogo=0, just logo=0...

yes, using the FDAPM, the computer was turn off.

so how we can update ACPIOFF, or the OS, for turn off the computer?

ok, try again...

in pure DOS mode:
- comment or skip by F8 string DEVICE=DISPLAY.SYS in CONFIG.SYS, if exist,
- remove or rename LOGOW.SYS and LOGOS.SYS files,
- set Logo=0 and Bootgui=0 in MSDOS.SYS:

[Options]
BootGUI=0
Logo=0

- extract WINEXIT.BAT, FDAPM.COM, WIN.ENG to WINDIR,
- rename WIN.ENG to WIN.COM with replace,
- reboot machine
- run WIN.COM:

C:\>win

- wait desktop, press Alt+F4, select Shutdown.

now u should see black DOS screen with executed WINEXIT.BAT.

i know that code works... but why not use these way:

1 - go from Windows to MS-DOS;(shutdown\exit the Windows)

2 - then turnoff the computer...

it will works

Step 1 is equivalent to hanging at the "Safe to turn off" message.

Step 2 violates the thread title!

Use a hot key to invoke FDAPM POWEROFF in MS-DOS mode.

1 - go from Windows to MS-DOS;(shutdown\exit the Windows)

so it was impossible until my patch for win.com.
for marketing cheats "Windows 95 is not DOS!" ms forced apm turn off procedure instead termination win.com (and make many other stup[id cheats in io.sys and win.com).
yes, there is some other patches for win.com that do like exit in dos.
but this patches do wrong way - they remain little resident code of win.com. my - not.

if u remove or modify WINEXIT.BAT - u get true termination win.com, and pure DOS after exit, w/o resident win.com code.
but if u have use usb kbd and/or mouse in windows - it does not work after that exit, until reboot.

i just need poweroff\shutdown the computer. without pressing the button by some seconds after the message "is safe turn off the computer"
