Here is the relevant BIOS menu.
Phoenix - AwardBIOS CMOS Setup Utility Power Management Setup +=====================================================+ | ACPI Function [Enabled] | | MODEM Use IRQ [NA] | | Soft-Off by PWR-BTTN [Instant-Off] | | CPU THRM-Throttling [50.0%] | | Resume by Alarm [Disabled] | | x Date(of Month) Alarm 0 | | x Time(hh:mm:ss) Alarm 0 : 0 : 0 | | | | ** Reload Global Timer Events ** | | Primary IDE 0 [Disabled] | | Primary IDE 1 [Disabled] | | Secondary IDE 0 [Disabled] | | Secondary IDE 1 [Disabled] | | FDD,COM,LPT Port [Disabled] | | PCI PIRQ[A-D]# [Disabled] | | | +=====================================================+

'Instant-Off' is the appropriate setting, right?
In a different menu, there are two other (relevant?) options:
PWRON After PWR-Fail [On] Watch Dog Timer Select [Disabled]
