[Qemu-devel] win2k installation: times

[Jim C. Brown]

On a Pentium MMX 200mhz, its been 29 hours and its still installing.
(At the "Saves settings" part, after "Installs Start menu items" and
"Registers compontents".) How long does it take on average?

It runs Windows 98 at a fairly nice speed. Installation was only an hour
or so for that. Takes a few minutes to boot. Windows 2000 takes 6 hours to
boot, but this is for the install. Does it boot faster afterwards?

Also, when the install is interrupted, it starts all over again. Not sure
if this is typical of Win2000 or is qemu-specific.

P.S. I have the Synaptic specifications downloaded. I can start writing the
qemu support, once I figure out how the PS/2 mouse is emulated.

It would probably be easier to add a command to the emulated mouse to switch
from reporting relative position to absolute position. This would need a
custom guest driver to use absolute positioning though. :/

The Synaptics touchpad has a special register sequence that switches it 
to absolute-reporting mode.  The bonus of doing it this way is that 
Linux/XFree86-based operating systems get free absolute positioning 
support (the kernel PS/2 layer has touchpad support built in).  Windows 
is the only tricky part of this implementation.

The touchpad emulation isn't as hard as I thought it would have been, for this
very reason. I have the info query mechanism fully coded, and am working
on the packets themselves. So much bitshifting is tricky but not inheriently
difficult.

BTW, am I the first to try this? Or am I duplicating someone else's work?

It took 2 days, 10 hours, and 40 minutes to install win2k on qemu-softmmu
on a 200mhz Pentium I cpu. Emulated with 32 mb of RAM, though if I had to
do it over again I would have given it 64mb. Still takes 6 hours to boot.
