Have you gone into the SMS yet to check firmware configuration (equivalent to BIOS menu)? When the 7248 is booting, when the keyboard icon displays, hit either F1 for GUI menu or F4 for TUI menu. You will need a copy of the SMS disk image on your floppy emulator. Some of the other F# keys do things, IIRC one of the higher F# keys forces the TFTP netbooting function, there's also probably one that does the same for CD- ROM. Key SMS Disk Required Function F1 Yes Graphical System Maintenance F2 No Select Boot Device F4 Yes Text-Mode System Maintenance F5 No Force Floppy Boot An FYI, this machine uses the “El Torito” Bootable CD-ROM Format Specification, so you need an ISO of that type, or it won't boot.
