Maybe Rudolf Marek can us help here, because he wrote the automatic generation for that ACPI table (SSDT).
Hi,
If I understand correctly, the 1800MHz is missing? If so, please check what is the portal frequency for this CPU. Maybe it is 2000 and not 1800 (so prop bios is wrong). Check the BKDG. I'm very busy so I think better would be if someone else could check.
The interupt driven parport works now?
Rudolf
