The problem is that if you take a brand new EISA motherboard out of the box, plug a 1742 or BT747 or any other EISA card with the floppy controller on it you can not boot from the floppy since the EISA card containing the controller has not been configured into the EISA conf structures, and thus by default the board will be disabled until you configure it. Catch 22, can't boot from the floppy controller on an EISA card to configure it. This is a very annoying problem with EISA cards that happen to also be your floppy controller card. It also rares it's ugly head even once you get it configured if the EISA config in NVRAM gets lost or corrupt, or if you move cards, etc, etc... -- Rod Grimes rgrimes@gndrsh.aac.dev.com Accurate Automation Company Reliable computers for FreeBSD
