Flash card and F/W for Mita KM-2030

Question

Hi guys,I posted a question recently for a Mita KM-2030 that was receiveing a Checksum Error F1. You gave me an answer of install new firmware via flash card. Which flash card do I need? Where do I get the flash card? How do I load the F/W onto that card so I can the follow your previous instruction of reloading onto the printer. I am a novice with this stuff, so please spell out all details. Thanks, Jerry
