Hi Mike, You really want to ask this on the fufu list: http://www.flexusergroup.com/flexusergroup/fufusub.htm I did about a year ago, but didn't get anything definite. The list tends to be bursty. It's been pretty quiet for the last couple of weeks.

Unfortunately, I only have the Percom floppy controller and I don?t know if FLEX compatible disk drivers and boot code were ever written for it. Before I go create Percom support for FLEX from scratch, does anyone have any leads? Mike
