The modules implementing various types of BootChannel's are daisy chained together. BootSwapGerm is the "real" importer of BootChannel and also exports BCnull, a dummy BootChannel to terminate the chain. To add a new driver named "BootChannelNew" to the chain: 1) Find the end of the chain, i.e. "BCn _ BootChannelX[...BCnull...];" 2) Change it to "BCn _ BootChannelX[...BCn+1...];" 3) Append after it "BCn+1 _ BootChannelNew[...BCnull...];" Κσ˜codešœ™Kšœ Οmœ1™
