ULTRA 5 OPENBOOT serial console disabling - for the use of USB key/mouse
I ve got an ULTRA 5, I installed a NEC USB PCI card in it, in works no problemo, I can use USB keyboard and mouse under X-WINDOWS (openbsd unix). But this works ONLY if I have classical SUN TYPE 5c keyboard attached.
Then the system boots, starts X and I can use the USB devices (key/mouse) under Xwindows.
But when I unplug the SUN TYPE keyboard out, and start the computer, I see just blank black screen on my monitor.
The X , or anything starts not. The display screen is and stays blank.
I think, this is because when I dont atach the SUN keyboard at the startup, the system switch output to the serial port console, am I right ?
Please, how can I disable this option ?
I want to use just the USB key/mouse. But when I start the system with no SUN TYPE keyboard, I see just black screen. What can I do with it?

thanx for answer, I can try, but I think there is no problem with booting itself.
If I connect SUN TYPE keyboard - everything works perfectly.
The problem just is, that when I have not SUN TYPE keyboard connected (I want to use just USB not SUN TYPE) I have blank screen at boot.
I think this is just because my ULTRA switches output automaticly to serial console, when It dont detects SUN keyboard at the BOOT.
Isnt it ?
Is it now possible to turn of serrial console in OPENBOOT when I dont want it?

Hello.
>> but I think there is no problem with booting itself.
If there was no problem when booting (this includes the X-server start-up) you would see the log-in screen on your display!!
=> Use the RS-232 console to look for errors!
I was just told by another member of this board that there is a document at SunSolve that describes the use of an USB keyboard for X. Unfortunately the access is password protected.

Well so, I can try.
Maybe you re right, because, also when the output is redirected to serial port, the display shoul be working when X starts, like you said, right?
Have I to do myself exactly the cable type you said {NULL modem with 3 wires} ?
I have somewhere a SERIAL NULL MODEM CABLE with DB9 - DB25 , but it is a full, 7 wires cable I tink - I used this to connect a PC-PC and a PC-AMIGA 500 :-> and it worked, as I remember. I hope this SERIAL NULL MODEM CABLE is a standard, or I will burn my serial port :->. First I will check it with the multimeter

Hello.
I could take a look on the document from SunSolve and they write you should set the input-device to ttya in OpenBoot:
ok setenv input-device ttya
Maybe in the other case the serial port will check if there is really something connected to the ttya input port. If the system works if something is connected to ttya but it does not work if nothing is connected (neither keyboard nor null modem cable) this may be the case.

-- EDIT --
The SunSolve stuff does not modify the X-Server configuration files but they modify the file /etc/system. They add a line like this to the file:
set consconfig:usb_kb_path="/pci@1f,0/.../keyboard@1"
set consconfig:usb_ms_path="/pci@1f,0/.../mouse@2"
(Both paths are relative to "/devices" and begin with "/").
This will make the keyboard usable even in the console login.
