I have an Intel PM55 chipset in my notebook. Reportedly Windows 8 (aka Windows Next) will not support BIOS-based systems. Is my motherboard forward-compatible to house an EFI firmware?

The Intel PM55 is available with the recent Core I5 & I7 chip families and is 64-bit.

As such, while your current system probably still only supports booting the BIOS-based OS via the Compatibility Support Module (CSM), and thus does not appear to be UEFI-based, actually it's almost certain to be UEFI-ready for Windows 8 which will be only UEFI-based and 64-bits.

However, you will need an EFI update package for your motherboard, which given the great popularity of the Intel PM55 chipset, has a good chance of eventually becoming available.

But nothing is ever guaranteed, as there is not enough documentation available at the moment.

Windows 8 will run on a legacy BIOS system.

It may not support all of the new Windows 8 features that require UEFI support, but it will still be as capable - if not more - than Windows 7 on a legacy BIOS.
