(Table 02648)
Call REBOOT protected-mode entry point with:.
AX = function
0100h warm boot
<p><b>Return:</b><br>Never
</PRE>
<p><b>Note:</b>
Broadcasts "Reboot_Processor" message, which is caught
by the VKD device
0201h set KERNEL Ctrl-Alt-Del handler
ES:DI -> new Ctrl-Alt-Del handler
DS:SI -> KERNEL reboot sanity check byte
<PRE>
<p><b>Return:</b><br>CF clear
</PRE>
<p><b>Notes:</b>
If an application installs its own handler and then
chains to Windows' handler, Windows will no longer
be able to detect hung applications, and will always
produce an "Application not responding" dialog
DS must contain a writable, fixed selector because
the provided address is converted to a linear address
before being stored
when Ctrl-Alt-Del is pressed in the system VM, Reboot
sets the sanity check byte to zero, schedules a
750ms wait, and then tests whether the check byte is
still zero; if not, it displays a message that there
is no hung application and then exits
0202h get KERNEL Ctrl-Alt-Del handler
<PRE>
<p><b>Return:</b><br>CF clear
ES:DI -> current Ctrl-Alt-Del handler
</PRE>
<p><b>Note:</b>
The default handler is located in KERNEL
0203h display "Application not responding" dialog box
ES:DI -> ASCIZ name of hung application
<PRE>
<p><b>Return:</b><br>Never if user pressed Ctrl-Alt-Del a second time
CF clear
AX = result
0000h user pressed Esc
0001h user pressed Enter
</PRE>
<p><b>Note:</b>
This function is used by the default Windows
Ctrl-Alt-Del handler
0204h set/reset protected-mode INT 01 handler
CX:EDX -> new protected-mode INT 01 handler
CX = 0000h restore protected-mode INT 01 handler
<PRE>
<p><b>Return:</b><br>CF clear
</PRE>
<p><b>Notes:</b>
If CX is nonzero, the current handler address is saved
internally before the new handler is set; this saved
address is then used when CX is zero on entry
used by Windows' default Ctrl-Alt-Del handler; actual
fatal exit to DOS will be done on next INT 01
<PRE>
<p><b>Warning:</b><br>Opened files are not closed and remain open as
orphaned files in DOS
</PRE>
<p><b>Note:</b>
Functions 0201h and 0203h are not useful outside the system VM
