You may not have 810 chipset driver installed. You should locate the driver
on Soyo mobo CD or download from Intel website.
If you want to know which mode is your harddisk work at, you should check
which ATA storage driver is installed in your computer. The default win98
busmaster driver is ATA-33, to use ATA-66 mode, you will need new driver
designed for your chipset, for 810 mobo, use the Intel driver from
www.intel.com (you should also find it on Soyo CD).

I recommand to use drivers from Intel website.
