There are no settings to disable APM/ACPI in the BIOS. The culprit is the main processor speed reduction system - thus resulting the system to slow the speed of the fans and literally shut down. Saying so - no help from Sony other than offering to change the MB for some $$$$. This seems to be a problem with most VAIO PCG-F2xx laptops.

Since I am able to get Win95 running and Win98 running (by disabling APM and ACPI) I think there should be a way how to get Knoppix running. Any insight in how to disable acpi/apm checking would be appreciated.
