Do I need a BIOS upgrade?

[WMIKED]

Hi,

I came across the following whilst browsing the Event Viewer:
Event Type: Error
Event Source: ACPI
Event Category: None
Event ID: 5

User: N/A
Computer: DESKTOP01
Description:
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.

My OS is Win XP Home and the MoBo is a Gigabyte Bx2000.

My system runs OK. Is this something that is going to grow into problem, or can I ignore it?

Thanks.

Update the BIOS, and see if that helps.
