I begin with suggested line in:


http://www.freedos.org/books/get-started/june14-manual-install.html



after creating the hard disk image with: "qemu-img create fdt2208.img 600M"



I am now using:

"qemu-system-i386 -name FreeDOS -machine 
pc-i440fx-4.2,accel=kvm,usb=off,dump-guest-core=off -enable-kvm -cpu 486 -m 64 
-overcommit mem-lock=off -no-user-config -nodefaults -rtc 
base=utc,driftfix=slew -no-hpet -boot menu=on,strict=on -sandbox 
on,obsolete=deny,elevateprivileges=deny,spawn=deny,resourcecontrol=deny -msg 
timestamp=on -drive format=raw,file=fdt2208.img,format=raw -cdrom T2208LIVE.iso 
 -audiodev alsa,id=mysnd -machine pcspk-audiodev=mysnd  -vga cirrus -display 
sdl -usbdevice mouse"



To be honest I don't understand all the options.



"-cpu 486" is probably slower than "-cpu host" but should give more similar 
results on different computers on which it is run.



The change is mostly a more recent version of defining sound devices (well, pa 
was maybe more recent... and unsure if pa would work),

and also specifying raw format to avoid restriction on block 0.

On some other system, I removed "-display sdl" as it was necessary because qemu 
was not compiled with SDL option (OpenSUSE Tumbleweed).
