I interpret the lack of answer as: none. isa(4) is usable on various architectures where the southbridge contains a LPC or similar. The MPC8555 CDS, for example, has a VIA southbridge that we need to talk to in order to get to the ATPIC for dealing with the nested interrupt. isa(4) is the device for this, but isaorm is causing kernel panics simply because the memory between 0xC0000 and 0x100000 is not reserved for ISA option ROMs. Likewise for Itanium, sparc64, etc... In short: scanning for option ROMs is not possible in all cases where ISA compatibility is provided. -- Marcel Moolenaar xcllnt@mac.com
