Or does EISA > present multiple channels via multiple I/O ports (multiple > advansys_board_found calls)? Multiple calls to advansys_board_found. The old code alternated between adding 0x20 and 0xfd0 to the iobase that it was testing. My new code probes base+0xc30 and base+0xc50, but calls advansys_board_found() for each of them. -- "Bill, look, we understand that you're interested in selling us this operating system, but compare it to ours.
