I want to get one of the Olimex ADuC7026 prototyping boards so I’ve been checking out the Analog Devices website. They have a free boot loading utility called the ARMWSD, but it seems to only have support for COM ports. I noticed that the olimex board only has the USB connection. So, how does loading the hex file work? Can I somehow use the free boot loader or is there something else needed?

The board has an FT232xx chip on it that converts USB to UART formated serial (COM) for the microcontroller. If your host is configured to operate USB as a COM port then you should be all set. I would imagine that they did it that way because RS232 COM ports are pretty rare on PC hardware these days. The board also has JTAG, so code can be loaded via the debugger as well.
