[Qemu-devel] 1) mouse and xinerama 2) ntvdm 3) win98se protection error

[Kevin F. Quinn]

Hi.

I've finally successfully installed Windows 2000 and SP4 from scratch with kqemu under linux.  I applied the IDE patch recently mentioned and that got around the disk-full problem.  This is on latest CVS.  I have an observation, and a couple of problems hopefully someone can help me with.

1) I've been using qemu with a dual-head setup, with xinerama.  I had trouble with the mouse, which behaved strangely on the second head.  Discovered it worked ok on the primary head.  Traced mouse data back through qemu, then SDL and worked out that for some reason the mouse position deltas aren't being served up properly to SDL (and hence to qemu).  A rummage around yielded an idea which did indeed sort the problem out.  Doing:

export SDL_VIDEO_X11_DGAMOUSE=0

before running qemu did the trick.  It seems DGA mouse behaviour isn't entirely sane yet with xinerama.  I don't think there's anything qemu can do; the data coming through SDL was bizarre.


Moving on, I have a couple of problems, but I can't think of a neat way to isolate and debug them.  If anyone has some tricks up their sleeves for this kind of thing, it'd be much appreciated.

2) ntvdm crashes, no matter what app I try to launch with it (ntvdm is the compatibility layer in NT for legacy apps).  The crash report on Windows 2000 (SP4) is as follows:

X#=0D, CS=00C7, IP=00003016
The NTVDM CPU has encountered an unhandled exception.  Choose 'Close' to terminate the application.

Choosing 'ignore' each time leads to more errors, with IP=000000E9, 000021E3 and 00000646 before the applicaion is forcibly terminated by Windows.

3) Windows 98 SE installation isn't successful.  It gets all the way through the setup to rebooting Windows proper (cloudburst Windows 98 background) however it crashes with "Windows protection error.  You need to restart your computer." before loading the desktop.  Stepping through Windows the initialisation shows it happens after the VXDs etc. have loaded (last one to load is psmouse.vxd).

Cheers,
Kev.

Regarding problem 2 and 3 - this is a problem with KQEMU regarding
running 16 bit applications. Last time I talked to fabrice, he knows
about this problem (thats why you cannot use KQEMU with win9x as guest
OS).

Thanks,
Hetz
