I read somewhere that host0 and host1 are assigned for on-board IDE interfaces, and IDE controllers on PCI slots receive host2 and up.

I was a little surprised myself, when the IDE controller I bought recently became host2...

Hello,
I'm trying to understand the structure of host0, host1, host2, etc in regards to IDE devices. I did read Richards FAQ, and he did discuss this for scsi devices, but I didn't see the logic explained for the IDE devices or whatever determines the host# scheme. ( ...or it was in there, but I didn't understand it ) If someone could explain this, I sure would appreciate it.


In regards to the /bus#/target# logic, maybe someone could confirm my understanding of this as well as I have listed below.

  /bus0/target0 =       primary master
  /bus0/target1 =       primary slave
  /bus1/target0 =       secondary master
  /bus1/target1 =       secondary slave.

I'm trying to get this fellows internal zip drive working on his system, but because he has a different HD and Zip configuration off his IDE slots than I do, it's necessary I understand how to figure this out so I can get his block device (part4) in the right place for his system.

Thanks,
Robert
