To configure a computer for a wheel mouse, press and release the
left
Control Key, type
"Q2"
,
and
press
<Enter>.
Follow with the Keep command to save the new setting in the unit's non-volatile
memory. To restore a computer which was previously set to wheel mouse to regular PS/2 use Q0
instead of Q2.
Null command
This command is used to re-synchronize an out-of-sync PS/2 mouse. Such a condition can result
due to transients, spurious power-up effects, or plugging and unplugging of cables with live
equipment. The command may need to be entered once or twice, depending if the mouse is out-of-
sync by one or two bytes. Microsoft mouse driver version 9.01 or later corrects this inadequacy of
previous drivers and renders this command unnecessary. To issue the command, press and release
the
left
Control Key, then type
"N"
.
Keep command
The Keep command saves the current state of the Vista's custom settings. These settings are scan
enable, scan interval, each CPU's mode and keyboard LED state, maximum computers, the
keyboard typematic value, and the mouse translation for each CPU. These settings are saved in
non-volatile memory and become the power-up settings. To enter the command, press and release
the
left
Control Key, then type
"K".
ROM Identification command
This command is used to identify the revision level of Vista firmware currently installed. Before
entering this command, your currently selected CPU should be at a command prompt, word
processor, or editor, so that when Vista sends the ROM revision level that the result will be displayed.
To issue the command, press and release the
left
Control Key, then type
"
I
"
. Vista will send back its
current firmware revision level, in the format
majorversion.minorversion
.
Reset command
This command is used to re-boot the mouse and keyboard without removing power from Vista. This
is most useful to reset a PS/2 mouse that has been unplugged and plugged back in. This command
is also useful to enable mouse data to be sent to a CPU that has not enabled the mouse. This may
be the case if Vista was not connected or powered off after a CPU was booted up. To issue the
command, press and release the
left
Control Key, then type
"R".
This command should not be
issued to a CPU which has a PS/2 mouse connected, but no mouse driver is loaded, since many
CPUs will crash if you send them unexpected mouse data.
Immediately upon issuing the command, you will see the keyboard LEDs all go on and then resume
their previous state.
