Install MacOS 9.2.2 on a qemu-based VM

Install MacOS 9.2.2 from CD

  • My qemu/kvm box is remote from my local machine, so I had qemu share the screen over vnc
  • MacOS 9 does not boot with more than 1024m of RAM, so 1024m of RAM is the max.
  • MacOS 9 will not boot with less than 64m of RAM, so 128m is probably a reasonable minimum.
  • Specifying boot option d will boot from the CD.
