For the record: the MIPS Malta board that we support also has direct PC FDD support. The real board has a SMSC FDC37M817 super I/O controller chip wired to Intel 82371EB (PIIX4E) south bridge's LPC interface and a suitable IDC header for a FDD data cable soldered onto the PCB as well. So it's not only x86 that can make use of floppy disk emulation. Note that there's no real ISA (no slots) on the Malta board, only the LPC and PIIX4E on-chip stuff. Maciej
