Hi i am thinking of upgrading my own private labb md110 that has been running BC11 but now the hdu crashed so as i am going to restore the lim back on track i was thinking of upgrading it to BC12 and preferly the latest sp what else do i need to watch out memory on LPU? FW on device boards i want to make a totaly new installation from scratch so i have the now how to fix a new disk and insert INL on it then i start the lim and it starts when and how do i use the limdisp that i have on my pc for me locking in to the files i se what i take as a range of command strings to run as batch is this correct what i meen is do i take the files and run them by winfiol as batchfiles trough the serial connection or is it files that i should put on the hdu path/? i sum it upp what i want is a lim up and running but i want to add all custumer data as extension numbers routs trunks etc on my own as a learning project i have been installing businessphone for 16 years and have worked some on md110 but not in the heart of system sw as i said i can make the disk ready for inl start but then i am a little confused about the limdisp a now that i have to have a bc12 lic file so thats no ? about the licens but the thing i am lost is wath steps from started lim on hdu/inl to a system ready for custumer data
