=====================================

the run scrip i use to install win98 (win98.sh)

=====================================
sudo umount /dev/shm
sudo mount -t tmpfs -o size=144m none /dev/shm
sudo modprobe kqemu
sudo mknod /dev/kqemu c 250 0
sudo chmod 666 /dev/kqemu
sudo qemu -boot d -hda win98.img -cdrom WINDOWS_98.iso
