Hi all,

Nobody can help me on this issue?

I'm in contact with the BIOS developer and we want to try to see if there is a possibility to fix the problem there.
Can I have at least more information (source code?) about the error message 'error sending to device'?

It seems also to be related with this:
http://community.qnx.com/sf/discussion/do/listPosts/projects.core_os/discussion.newcode.topc9406
And there Malte Mundt told that it's a known problem. Can someone give more details?

The solution he gave on that topic can help to get the system to run but it's really annoying to have to do the 
installation on a first system to use on an other one.

Really nobody?

Is there a way to get at least the source code to see if this can be fixed at the BIOS level?

I'm sorry for this 3rd reply to myself but this problem is really annoying for our customer and I still expect that 
someone in the QNX team in charge of this can handle this.

Today I get this report form your BIOS developer. It show that the problem is inside of diskboot and then we can't solve
 the problem without the help of QNX.

Thanks,
Christophe

Here is the report:
I have a F18 and the emulator connected. During the message 'Now starting io-hid' I can see, that the QNX-code access to
 the port 64.
Normally, there is a register from the keyboard controller which returns a value (for example a key is available or not 
available).
But in our case there is nothing and the return value is FFh; QNX testing the return value in a loop in the hope of 
status change.
But there is no change and QNX reports: 'error sending to device'.
From my side I would say, that QNX doesn't support a "legacy-free PC" design (like our F17/F18/F19).
Legacy-free means, among other things, that there is no keyboard controller on the I/O ports 60h and 64h.
The chipset of the F17/F18/F19 support this legacy mode and provides a special functionality at the USB controller.
For the USB controller it is possible to configure normal PCI Interrupts or SMI Interrupts. Furthermore it is possible 
to select that a read on port 64h will cause an SMI event. With the help of this mechanism it possible to install a code
 at the SMI handler, that could be able to emulate a keyboard controller.
The BIOS configures the USB controller in this way and the keyboard emulation is active during the BIOS-POST, at DOS and
 for example at the GRUB bootloader.
 
What happens if QNX starts?
 
QNX reinitialize the USB controllers and confígures 'normal' PCI interrupts and switch-off the functionality that a 
read on port 64h will cause an SMI interrupts (I can see that also with the emulator). 
--> So it is not possible to install a code that can emulate a keyboard controller.
 
Sorry, but this is also valid for the F19P. It is necessary that QNX supports the USB keyboard with a proper USB stack.
