I have an ASUS P5A mobo, with an AMD K6-2. I have Windows 95 installed on it. Funnily enough, when I first set this computer up I was using Windows 98 (a memory patched, quick install version) to troubleshoot before switching to Windows 95. All the hardware is the same, but on that install it DID, on shut down, give me the "It's now safe to turn off your computer" message.

The ["It's now safe to turn off your computer" message] belonged in the category computers that did not support software-initiated power-off. In other words computers with AT style power supplies that had to be shut down manually. Your ASUS P5A is from the ATX generation and shuts down automatically.

It's still possible to get on atx systems, if you forcibly disable ACPI on installation time.

Run setup with the '/p i' arguments.

If you dont want acpi run setup.exe /p i
If you want acpi run setup.exe /p j

When I had Win 98 installed it did it, though. So at least in 98 it's still possible to have active.

...this means I have to re-install, doesn't it?

Pretty much.

Sorry. 🙁

It's OK, thanks! I've kept a CD-RW that I keep adding stuff to as I need it with this computer, everything from the drivers and whatnot up to some smaller games and wallpapers - whenever I need something else I just add it to the CD, so even formatting and re-installing I should be back up and running to where I am in about an hour 😀

Thanks everyone for the help! I'll report back once I'm done!

I can enable the Orange Screen of Nostalgia on my Win98 system by just disabling APM in the bios. This is on a newer skt775 system with a Via chipset.

no it doesn't

windows 95 doesn't support ACPI at all so the setup.exe /p stuff doesn't even apply at all (it's only for win98)

if you reinstall you're just wasting your time, it isn't ACPI that is facilitating win95 to power off your system automatically, it's APM

if you want to disable APM just turn it off in BIOS, simple as

Where in BIOS 🤣 as I explain above, I can't find the settings in BIOS. There are power management settings but none are relevant to shut down and I couldn't find anything in the P5A manual about it.

The power options is a choice made at install that I didn't know about, I don't have it. I recall reading a couple days ago that it's not something that can be added post install 🙁

Have you tried disabling APM (unchecking "Enable power management support") post install ?

Ack, thank you for sharing the unfortunately negative result.

Someone mentionede that ACPI is not supported, why it does not give error at
those commands then? I alaways install Win95 and Win98 @ setup.exe /p j /is

Both have : ACPI Power save mode partly supported (except of Suspend to Disk)

It's not disabled in your screenshot. In the attached image it is set to "user define"

I understood that that wasn't an actual screenshot, but an image from the manual, and not what OP had in their BIOS.
