The RomWBW will be booted at power up. It takes 23 seconds to load and boot RomWBW from reset. Due to limited ROM code space in EPM240, only SD cards up to 2G are supported. Another word, **SDHC (2-32GB) and SDXC (32GB-2TB) are not supported** |

| Note, Serial port for RomWBW will work without hardware handshake, however to transfer files using XM.COM in RomWBW will require a serial port with hardware handshake capability and terminal emulation that supports hardware handshake such as TeraTerm. The handshake signal needs to be CTS (not DTR). Picture below shows modifications to the common 6-pin CP2102 USB-serial adapter to enable hardware handshake. | Note, Serial port for RomWBW will work without hardware handshake, however to transfer files using XM.COM in RomWBW will require a serial port with hardware handshake capability and terminal emulation that supports hardware handshake such as TeraTerm.
