Dear Swift Happy New Year. >Quick question, what machine types (IPxx) will this bootloader work for? Is it only for the Indigo? Target machine is No ARCS machine. (Personal IRIS 4D/35 and Indigo R3000) https://dmesgd.nycbug.org/index.cgi?do=view&id=4694 https://dmesgd.nycbug.org/index.cgi?do=view&id=4693 Of course, I'm going to adapt Personal IRIS 4D/25. (That is not difficult.) In addition, I confirmed that operation on Indy and Indigo R4000(ARCS machine).
