Hello,
I'm reacting a bit later but I have a trouble with an old DOS OS from Digital Research called Concurrent DOS. It worked fine till Qemu v0.11.1. I tried it with a lot of versions from 0.12.0 to 1.0.1 and it boot correctly. But after a key pressed, I can't use the keyboard any more. The system is not freezed (there is a clock in the bottom side of the screen which is running) but I can't use the keyboard any more. It worked also with 0.12.0-rc1 and the PC-BIOS. It seems that with Seabios it doesn't work any more but PC-BIOS is no longer supported by QEMU (from v0.12.0).
Do you know what can I do ?
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.
