Call it the typo monkey, but yes it should be ".config" not "config"

Things seem to go well, except for this little annoyance: When I power the system off it gets to the point where it says "System halted" and never actually powers off automatically. I think it has something to do with my system BIOS still supporting APM whereas Slackware 14.1 does not support that.

Anyhow, I am stuck. Somebody suggested that I need to build a custom kernel to get this APM module back but I do not have the faintest idea of how this is done, or even if that would solve my problem.

Anyone willing to help me solve this?
My Pentium III PCs are both 733 MHz, and none of them touch APM. Use the hints elsewhere in this thread, and set up ACPI in the kernel config. When you do that, also check that you want the ACPI "Button" from the ACPI submenu. After that's done, you might need to get acpid running in order to use that power button. That seems to be the one setting that makes a difference.

The PC might support APM, but really, let it die if you are able. It was truly useful for the original Pentium, less useful for newer computers.

But doesn't your suggestion assume that my BIOS allows for the ACPI shutdown mode which somebody before says is usually branded as "Allow Software Power Off"? I don't have such entry (unless it is well hidden!) in my BIOS.

It's possible. None of my Pentium III PCs (Dell) give me the choice of whether I want software powerdown: It just does it, and the only "hardware" powerdown is to hold down on the power button for 8 seconds. [The eldest PC has a separate reset button, though.]

There's a program that probably comes with Slackware, called `dmidecode`, and you can run it just like that, without arguments. Should your Slackware be set up to read the DMI tables, dmidecode will show you whether ACPI or APM is supported by your PC. It could very well be that both ACPI and APM are supported.

maybe look at the bios version and date would give a clue? @mlslk31 & @tb75252

maybe mlslk31 has a "newer" old bios then tb25252?!?

Maybe

The PC has always been as I describe, but it did have to be re-flashed to I could gain control of my serial ports...

Code:
Hardware name: Dell Computer Corporation L733r /CA810E, BIOS A14 09/05/2001
...and that was the last BIOS upgrade offered by Dell for that PC.

Really, I'm tried to be skeptical in few words and didn't get the point across sufficiently. When I think of a time when APM was the dominant standard and worked comparatively well, I'm thinking about the Pentium 100-MHz PC up into the Pentium-MMX 200-MHz range, maybe a little earlier, maybe a little later, but certainly not Pentium III, not as the way that works best. It may still work, especially if ACPI is ripped out altogether, but I'd try that as the very last resort.

How's this issue coming along, anyway? It dawned on me that the kernel ACPI code has a default cutoff year that can be compiled into the kernel...

Code:
CONFIG_ACPI_BLACKLIST_YEAR=2001 # default
...or you can set acpi=force on the kernel command line. In that spirit, what is the output of `dmesg` after boot? Should you be having a BIOS-too-old problem, the kernel should remind you that you can use acpi=force...if you still have ACPI compiled into the kernel.

Also, for software powerdowns, I'm fairly sure that acpid has to be running in addition to the ACPI kernel code being present, else the PC is at the whims of the default power button behavior. On my oldest PC, that means instant shutdown without unmounting drives.
