I ran qemu 1.0.1 and the latest SeaBIOS (from the git) with the following options : qemu-system-i386 -L git/bios -fda disk.img -no-fd-bootchk -boot a -m 16
Here is the log : https://docs.google.com/open?id=0B7mz0vq6Rpb7UE1ibjJDcEhTRWlNV050QnMyMWwtZw Here is the floppy disk image I used : https://docs.google.com/open?id=0B7mz0vq6Rpb7bHpYaEt2SnVUUi1KaWE3a3lBQUJpQQ The floppy disk is simply a C-DOS 720 Ko floppy created by "format a: /s". So it's quite empty. Qemu doesn't crash or freeze. But I can just type a single character and the nothing else. But the system is still running (there is a clock at the bottom right of the screen).

You can help debug the issue so it can be fixed in SeaBIOS. Start with producing a log from SeaBIOS by adding (on a recent qemu) the following to the command-line: -chardev stdio,id=seabios -device isa-debugcon,iobase=0x402,chardev=seabios Also, if there is an image available for download, other developers can take a look at it as well. -Kevin
