[Qemu-devel] [Bug 1276879] Re: lots of dma command 10, 14 not supported

[BALATON Zoltan]

I don't know about Bochs but here's another page with resources on running 
OPENSTEP on a VM:
http://www.zebpedersen.co.uk/?p=126
The VMWare drivers (both svga and mouse) should work with QEMU too but I don't 
know if they are compatible with NeXTSTEP.
Now I remember there was some problem with mouse emulation with the PS/2 or 
serial driver also on VMWare which made the mouse pointer jump around and then 
freeze. This may also happen with QEMU but it was never debugged AFAIK.

Title:
  lots of dma command 10, 14 not supported

Status in QEMU:
  New

Bug description:
  Trying to install NeXTSTEP 3.3 onto a 2GB file with QEMU 1.7.0.
  In the terminal that started QEMU, there are a lot of
      dma: command 10 not supported
  and 
      dma: command 14 not supported
  messages.  When the installation of NeXTSTEP gets to
  'preparing disk for nextstep installation', there are a lot
  of messages that ATA command c5 failed and other info.
  The result is a failed installation.

  Is this a bug in QEMU?  Is there a workaround, e.g. by
  disabling DMA altogether?

  thank you
