Select the Device Manager tab
Near the bottom of the list, you should see an entry called 'System Devices'. Click on the [+] sign next to System Devices to expand that branch.
You should see a reference to 'Intel 82810' somewhere in there. If it states '82810E' then you have the Intel 810e chipset, otherwise if it just says '82810' , then its the standard 810 chipset.
