I was experimenting with old MS-DOS 6.22 under QEMU with the 'isapc' machine type, and found it is not able to reboot the guest. Bisecting QEMU blamed the QEMU change that rebased from "rel-1.9.3", to "rel-1.10.0". Further bisecting SeaBIOS blames this change:
What version of QEMU are you using? I can't get anything to run with the isapc machine type - I just get:
I've tested many QEMU versions when trying to narrow it down, including current git master.
I'm building current GIT master on Fedora 27, using:
./configure --target-list=x86_64-softmmu --disable-xen \ --prefix=$HOME/usr/qemu-git make -j 8 make install $HOME/usr/qemu-git/bin/qemu-system-x86_64 \ -fda ~/FLOPPY.img -monitor stdio -M isapc,accel=tcg
Where 'FLOPPY.img' is the FreeDOS download from
http://www.freedos.org/download/download/FD12FLOPPY.zip
That's an installer image - just wait till it displays the first install screen to "select a language".
Then in the QEMU monitor console I do
(qemu) sendkey ctrl-alt-delete
I didn't think isapc was functional at all.
Yep, it should work, within limits of its feature set of course.
