BootChannel implementations. 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...];"
BC0 ← BootChannelDisk[
Basics, BC1, GermPrivate, PrincOpsUtils, ProcessorFace, SA4000Face];
BC1 ← BootChannelEther[
BCnull, Basics, GermPrivate, MiniEthernetDefs, PrincOpsUtils, ProcessorFace];
END.
