I built and booted a kernel with the following in the config file: controller bt0 controller bt1 at isa? port "IO_BT0" bio irq ? vector bt_isa_intr The PCI probe found the card first as bt0; the ISA probe found it later as bt1. In the interest of minimizing possible damage to my file systems, I'm afraid I hit the reset button while the bt1 portion was ``waiting for scsi devices to settle'. -- Rich Kuhns rjk@grauel.com PO Box 6249 100 Sawmill Road Lafayette, IN 47903 (317)477-6000 x319
