Description Robert Tiismus 2002-07-08 17:20:01 UTC 
On Intel SDS2 mainboard, the apm0 device is silently ignored, or the error
message 'apm:16-bit connection error.' is printed and the device will not be activated.

How-To-Repeat:  - compile kernel with: 'device apm0 at nexus? disable flags 0x20'
and apm will not be discovered at all.
 - compile kernel with: 'device apm0' and the error message is printed.

It seems that Intel SDS2 does not have APM. APM Init results in APM BIOS 
v1.2 detected, but protected mode 16 bit connect gives APM not available 
error code. APM is also not mentioned in SDS2 manual. It seems that 
power is managed solely by means of ACPI.

Case closed.

State Changed
From-To: open->closed

Closed at submitter's request as MB in question does only ACPI not APM.
