I tried a modifed version of the above, and it worked fine for me. qemu-system-x86_64 -snapshot -L test -device piix3-usb-uhci -drive id=usbflash,file=dos-drivec-new,if=none,cache=writeback -device usb-storage,drive=usbflash -chardev stdio,id=seabios -device isa-debugcon,iobase=0x402,chardev=seabios What version of qemu are you using? There are a few known quirks in the seabios code that were fixed recently, but I did not think they impacted the qemu emulation. -Kevin
