+Test VM - nt4sp1 - Windows NT 4 Service Pack 1
+==============================================
+
+Setup:
+ - Configure a VM t-nt4sp1 with default Windows NT 4 settings.  Make sure to
+   configure the disk to 8 GB or higher capacity (2 GB suffices).
+ - Make sure networking is NAT.
+ - Install Windows NT 4 SP 1. Create a user 'test' without a password.
+ - Insert the validation kit ISO and install the test execution service (see
+   vboxtxs-readme.txt). (As Administrator.)
+ - Disable CD autorun:
+      - Start regedit.
+      - Set the value HKLM/System/CurrentControlSet/Services/Cdrom to 0.
+ - Shorten boot menu wait, disable automatic reboot on STOP, make it write a
+   dump:
+      - Right click on "My Computer", select "Properties" and go to the
+        "Startup/Shutdown" tab.
+      - Change the "Show list for" entry field to "1" second.
+      - Uncheck "Automatically reboot".
+      - Check "Write debugging information to".
+      - Check "Overwrite any existing file".
+ - Eject the CD and shut down the VM.

+Test VM - t-dos20 - PC-DOS 2.0 on a harddisk
+============================================
+
+Setup:
+ - Create a default DOS VM 't-dos20', but restrict the disk size to 31MB.
+ - Partition the disk with a single partition.
+ - format C: /s
+ - Install (copy?) the DOS files to C:\DOS
+ - Copy DosSleep.exe and DosVmOff.com onto the disk.
+ - Create config.sys if needed.

+=================================================================================
+
+Setup:
+ - Create a default DOS VM 't-dos401-win30me', but restrict the memory to 4MB.
+ - Install DOS (single partition, etc).
+ - Install CDROM driver (e.g. OAK).
+ - Install Window 3.0 multimedia edition into C:\MWINDOWS.
+     - Select tandy soundblaster driver, make sure to configure
+       them correctly (port 220, irq 5, dma 5/7) or they will hang
+       the system.  Check that it works.
+     - Disable the tandy welcome screen.
+ - Copy DosSleep.exe, DosVmOff.com, and WinExit.exe onto the disk.
+ - Start the macro recorder (recorder.exe) in windows and record two different
+   macro files, both which are associated with Shift-F7 and play in normal time.
+   First C:\WinExit.Rec:
+     - [Anything that might be useful+easy to test in read mode]
+     - File->Run in the program manager using keyboard (Alt-F, R)
+     - Type in "C:\WinExit.exe" and enter (no mouse).
+     - Save macro.
+   Second (hit File->New first) C:\TestMM.Rec:
+     - File->Run in the program manager using keyboard (Alt-F, R)
+     - Type in "welcome.exe" and enter (no mouse).
+     - Wait for the tandy welcome animation to finish.
+     - [Anything else that might be useful+easy to test]
+     - File->Run in program manager again.
+     - Type in "C:\WinExit.exe" and enter (no mouse).
+     - Save macro.
+ - Edit win.ini changing the REC file association to:
+       rec=RECORDER.EXE -H +F7  ^.REC
+   This allows us to load .REC with Shift-F7 macros inside them at startup and
+   execute them.  (Windows 3.0 didn't have a startup folder.)
+ - Make a copy of win.ini called win-mm.ini changing the 'load=scrnsvr.exe'
+   statement to 'load=c:\testmm.rec'.
+ - Make a copy of win.ini called win-exit.ini changing the 'load=scrnsvr.exe'
+   statement to 'load=c:\winexit.rec'.
+ - Create c:\test.bat with the following content:
+       :dos-stuff
