I am in the process of sorting someones HP Pavilion 7915 pc which is running Windows XP Home which is booting slowly and shutting down slowly. I have upgraded it to service pack 2 with very little difference and upon looging in the event log discovered this recuring problem.
AMLI: ACPI BIOS is attempting to write to an illegal IO port address (0x70), which lies in the 0x70 - 0x71 protected address range. This could lead to system instability. Please contact your system vendor for technical assistance.
I have clicked the link to go to microsoft support which tells me i need to obtain bios updates. I have looked on HP's site but been unable to find a bios update for this machine.
Can anyone help?
