Yes, we did replace the IDE driver with our own implementation.  But you 
can apply this patch that was posted long ago on the list that takes 
care of it on regular QEMU.  It will slow things down a bit, so you may 
want to disable it, so you may want to optimize it or disable it after 
you get Windows 2000 installed, but it works.  The issue seems to be the 
fact that the install-time Windows 2000 IDE driver doesn't like write 
operations generating an interrupt too quickly (i.e. before the "out" or 
DMA transfer returns).  It doesn't seem to have this issue after the 
base OS is installed and booted however, but your experience may vary. 
Attached is the patch that we found on the list.  It applies both to 
0.6.1 and 0.6.2, albeit with some possible hunks.

Best regards,

Leo Reiter
