SP2 and Headless keyboard reg entry doesn't seem to work

[Juhan Palm]

Hi,

A rather serious issue for us has been noted with XPe SP2.

Since our devices are often used with a barcode scanner
and a touchscreen only, we need to be able to boot without
a PS/2 keyboard, and to have the keyboard port accepting
scanner data, or a keyboard plugged in after boot.

This well known reg key has solved it so far :

HKLM\System\CurrentControlSet\Services\i8024prt\Parameters\Headless
REG_DWORD 0x00000001

But it does not seem to work with XPe SP2 !

Hi Juhan,

You are saying that this worked on SP1?
Please check this value again by using regedit from XPe.

Also if you have not already go trough this article.

Is there a fix for the VGA as well? We have a system that is NOT configured
as Headless, however normally it does not have a monitor attached. One can
be plugged in at anytime for diagnostics or configuration. If the monitor
is not plugged in during boot, then it will not work later. In other words,
it's not hot plug recognized.

Richard,

If you monitor, display adapter and display driver are Plug and Play (double check your hardware documentation) and the monitor is
not detected during hot plug, you may want to check SetupApi for possible errors or detection indication.

Also, make sure you don't connect the monitor by using a switch box.

And, of course, test it with XP Pro first.

Hi Slobodan,

Yes, it worked fine on XPe SP1.

To be able to start the device and plug in a keyboard afterwards
or to boot with a keyboard wedge scanner only is absolutely a
must for us.

Is there a new workaround in SP2?
Anyone at MS who knows what it is?
