Hello Legacyman13, please bear in mind that this product has reached its End of Interactive Support so Intel no longer provides interactive support for this product via telephone, chat or e-mail since December 2009. http://www.intel.com/support/motherboards/desktop/sb/CS-031088.htm
However the Intel ® motherboard D975XBX2 does support a 5.25 floppy disk drive. Any additional information you may need on this board please check the following link Support for the Intel® Desktop Board D975XBX2http://www.intel.com/p/en_US/support/highlights/dsktpboards/d975xbx2
THANK you for responding!
Haha, I am aware that the board is old enough to no longer be supported, but it does suit my needs perfectly and still has plenty of modern hardware on it to make it a useful machine. The 5.25 floppies are the hardest to integrate onto modern motherboards, so this is awesome news to hear that a relatively new board provides the necessary BIOS configuration.
Excellent, thank you again!
