That patch is here: http://www.clustermatic.org/pipermail/linuxbios/2003-October/005753.html > > > Maybe someone need to make it can handle peer root bus refer to the code in > > > Linux kernel or Etherboot. > > > > Can we have an array of peer busses in the config file? > > ie. register SCAN_BUSSES={ 0, 1, 3 } I like this idea implemented in FILO, rather than having 2 options (recurse from bus 0, and scan 0-255).

That would be the right solution eventually. -- Takeshi _______________________________________________ Linuxbios mailing list [EMAIL PROTECTED] http://www.clustermatic.org/mailman/listinfo/linuxbios
