I note that my config.sys has psd=acpi.psd and I know I need more.

I installed the files from acpi13042008.zip, all files dated 13
Apr, overwriting files from Dec.

So I hunted around and found:
PSD=ACPI.PSD /SMP /TMR /APIC /R /CD /!NOD

When I boot with that I get a few screens full of logging unmasking
IRQ data but the wps never starts.  It logs C-A-D, power button,
A/C plugged in and unplugged.

I changed it to PSD=ACPI.PSD /SMP /APIC /!NOD with no luck.

And PSD=ACPI.PSD /SMP /APIC allows a boot.

Sooooo.  What should the psd= line be?

Thanks Jon

  
Jon, first of all, the OS2APIC.PSD and ACPI.PSD are mutually exclusive. The latter is *not* ACPI aware, but rather, works with SMP machines in a generic mode (certain system manufacturers might provide a PSD specific to the hardware, such as HP (Compaq) Proliant servers.

On the T61, what I've found to work best is:

PSD=ACPI.PSD /SMP /APIC /SAP:0x20

People have reported mixed results with the /!NOD parameter, which probably was more useful with earlier builds of the ACPI PSD than with the latest ones (>=3.05). The SAP parameter set as it is above forces the ACPI driver to leave some of the interrupts alone and not try to monkey with all of the hardware. I found this necessary with 3.08, whereas it was not with 3.07. Likewise, desktop systems based on the Intel 945 chipset seem to prefer this setting.
