9.6 ACPI Runtime Checkpoints
ACPI checkpoints are displayed when an ACPI capable operating system either enters or
leaves a sleep state. The following table describes the type of checkpoints that may occur
during ACPI sleep or wake events:
Checkpoints may differ between different platforms based on system configuration.
Checkpoints may change due to vendor requirements, system chipset or option ROMs
from add-in PCI devices.
HIGH BYTE XY
The upper nibble ‘X’ indicates the function number that is being executed. ‘X’ can be from 0 to 7.
0 = func#0, disable all devices on the BUS concerned.
1 = func#1, static devices initialization on the BUS concerned.
2 = func#2, output device initialization on the BUS concerned.
3 = func#3, input device initialization on the BUS concerned.
4 = func#4, IPL device initialization on the BUS concerned.
5 = func#5, general device initialization on the BUS concerned.
6 = func#6, error reporting for the BUS concerned.
7 = func#7, add-on ROM initialization for all BUSes.
8 = func#8, BBS ROM initialization for all BUSes.
The lower nibble ‘Y’ indicates the BUS on which the different routines are being executed. ‘Y’ can
be from 0 to 5.
0 = Generic DIM (Device Initialization Manager).
1 = Onboard System devices.
2 = ISA devices.
3 = EISA devices.
4 = ISA PnP devices.
5 = PCI devices.
