+# Windows 98
+
+The installation process is quite different since Windows 98 will be incompatible
+with most of the defaults in virt-manager.
+
+## Install
+
+https://en.wikibooks.org/wiki/QEMU/Windows_98
+
+https://wiki.gentoo.org/wiki/QEMU/Options#Display_options
+
+You'll need to install from command line like so:
+
+```bash
+qemu-system-x86_64 \
+    -cdrom /var/lib/libvirt/iso/windows98se.iso \
+    -boot order=d \
+    -drive file=/var/lib/libvirt/images/win98.qcow2 \
+    -m 512 \
+    -device sb16 \
+    -display sdl
+```
+
+- cdrom allows us to use the ISO image. It's also possible to use virsh to
+  forward a physical drive to a file, but reading the data from the hard drive
+  is usually faster.
+
+- boot allows us to specify the order to d, which is the CD.
+
+- drive allows us to use the image we just created.
+
+- enable-kvm turns on hardware acceleration in x86 using the kernel VM. KVM
+  causes problems on Windows hosts when shutting down the guest and can even
+  prevent it from starting in some cases. If this occurs, you can safely remove
+  it from the command.
+
+- m allocates the guest's RAM. In this case we use 512, but going above it can
+  be dangerous for Windows 9x.
+
+- device allows us to add a device driver, in this case, the Creative
+  SoundBlaster 16 sound card (sb16) to get audio. Standard Windows 98 discs
+  ship with drivers for it, and if you haven't used this flag while installing,
+  it would need to scan for it.
+
+- display allows us to use an alternative display engine rather than GTK+. In
+  this case, we use Simple DirectMedia Layer because it doesn't conflict as
+  much with fullscreen support. You can press Ctrl+Alt+F to enter and exit
+  fullscreen mode and Ctrl+Alt to have QEMU grab or ungrab the keyboard input
+  and invoke the monitor as usual.
+
+
+## Boot
+
+We'll boot with the same command we used to install but without the boot parameters
+
+```bash
+qemu-system-x86_64 \
+    -drive file=/var/lib/libvirt/images/win98.qcow2 \
+    -m 512 \
+    -device sb16 \
+    -display sdl
+```
+
+
+```bash
+sudo qemu-system-i386 \
+    -name "Windows 98" \
+    -L pc-bios -nodefaults -no-hpet -no-reboot -display sdl \
+    -M pc,accel=tcg -cpu pentium3 -m 1024 \
+    -drive file=/var/lib/libvirt/images/win98.qcow2 \
+    -device VGA -device sb16 -device rtl8139,netdev=net0 \
+    -netdev user,id=net0,hostfwd=tcp::8080-:80,hostfwd=tcp::2222-:22 \
+    -rtc base=localtime,clock=host
+```
