Re: firmware for my mendelparts mendel?
you will need to upload the FM to your printer
2)win xp mode - win virtual pc might help you there (if you have pro/ult)
never used them so cant help you with the details
3)you can use something like www.virtualbox.org
to run a 32bit os (like xp or Ubuntu, not sure about win7 though)
4)or a laptop/other computer?
have you downloaded the arduino-0018-incl_sanguino.zip and the latest ********_FiveD_GCode_Interpreter.zip from the mendel parts download page?
