I've tried change the SCSI ID of the boot device, but this discussion was about adding devices. On a Mac, I've always been able to add devices, whether they be on an exiting SCSI or IDE bus, or on a new bus, and not worry about the machine not booting. I can't same the same about the PC. Overall, the PC is just much more sensitive to device changes than Macs are. And I think it's because the Mac BIOS and OS are just designed to handle this better. The PC BIOS never had any provision for a third-party boot device to annouce itself. -- Timur Tabi - ttabi@interactivesi.com Interactive Silicon - http://www.interactivesi.com When replying to a mailing-list message, please direct the reply to the mailing list only.
