Hi rfpup!
You can use EPROM or EEPROM for MFU! But there are different Files for them! I dont know why, but it is! For example you can not use File R6A EEPROM File when you have EPROM or backwards. So there are almost two of one Released Software. One R6C for EEPROM and one R6C for EPROM. At delivery there are EPROM on MFU!
