!KVM switch with ABIT NF7-S

I have a LinXcel USB 4-port KVM, for switching USB mouse and keyboard
and video. The NF7 hangs at the beginning of Windows XP if I am
routed through the KVM. After I boot, I can switch the cabling over
to the KVM and then add a second machine. It seems to be the video
detect that kills the Windows boot.

Any thoughts? Any switches in BIOS that might help?

 

Interesting. I have a Belkin 4-port KVM with audio/microphone, and my
NF7-S2 boots just fine when connected to it. My problem is that the mouse
is not recognized through the KVM. I've tested the mouse, all cables and
all ports on the KVM, and everything works fine. I have to plug a second
mouse directly into the machine (PS/2 or USB) to get a working mouse with
this board. I've never run into this before and have built and run *lots*
of machines through KVMs. Never had a problem till now.

Good luck,

Margaret

 

Funny you said that about the mouse. I have a 4 port KVM box as well. My
PS/2 mouse does work but usually only after a second boot. The first time I
boot my NF7-S v2, the mouse is all erratic and impossible to control. I have
to use the keyboard to turn off the machine, power it off at the mains and
then reboot and the mouse works just fine again.

Thought I was unique but maybe there's a problem with Abit NF7 based boards
and KVM boxes. Anybody else with any experience / solutions ?

 

No solutions, but a question and two comments :

the question - Is this predominantly USB mice?

the [ 2 ] comment -

I used this ( UK02PE ) ' cheap as chips Hong Kong shipped KVM and
have connected many hundreds of different old /new / puters with never
a single problem, this to include video dongle-to-KVM for some [DELL]
built machines.

I now use the 4 port version of the same thing - bought from the same
person, equally with no probs

BTW, I'm on an EquitO BIOS - not that it should make any difference !

No, I'm using a PS/2 mouse. My KVM does have the ability to use USB (not
for the console), but for the client machines. It's got one USB cable
that's supposed to handle both mouse and keyboard. I have one set of these
cables, and so far it's only worked on one machine. All others give me
either keyboard or mouse but not both. So I stick with PS/2 and all has
worked fine, except for this one machine (NF7-S2).

May not be pertinent, but on my NF7-S I found that my logitech ps2 mouse
only worked on second boot of my pc until i installed logitech drivers.

 

Thus spake ?uzzled:

When I had KVM/mouse problems the culprit turned out to be the
+5V-standby line from the power supply.

Apparently on a lot of these boards, the mouse/keyboard controller is
powered from +5VSB (to allow for the possibility of wake-on-keypress).
My KVM was trying to pull more power from the PS/2 ports than the
PSU's +5VSB could provide.

 

Thanks for the info. But I've got a Microsoft Intellimouse Optical, and
drivers are loaded. Rebooting makes no difference. :-( I see the mouse
pointer, but it's stuck in the middle of the screen.

Margaret

 

A mouse can certainly be a problem. I would suggest "Mouse Hunt" a good dvd
to start with.

from page 9 of the dvd, I mean my cybex switchview manual...

Mouse...

Mouse jumps or "hugs" screen

If the mouse has been hot-plugged while running in windows, you may
need to close and restart windows.

If the mouse still does not function, try the mouse resynchronization
command <ctrl><ctrl>ZM<enter>

Mouse is inoperable on one or more channels

Try the mouse reset comand: <ctrl><ctrl>MR<enter> for ps/2 mice,
<ctrl><ctrl>MW<enter> for intellimouse.

Mine is a 4 cpu cybex switchview, ps/2. The ps/2 port for the mouse emulates
a logitech mouse, like if you don't have a mouse, win xp still thinks you
got one, when its all plugged into the switch view.

I haven't had mouse problems for awhile, switching from computer to
computer.

I have 3, nf7-2 and an intel cpu connected, recently replaced the nf7s with
dfi landparty socket 754.

Used the same memory on the 754...and the hard drives.

No mouse problems...I use a logitech mouse, has a pretty roller on top, that
my thumb moves, and that scroller wheel thingy my index finger uses.

my 2 cents

Wow, you have the same switch box as me.

This is my problem.

It does it when I first boot the machine. All the cables are already plugged
in and hasn't been hot plugged.

I don't understand this. Do you hold down both CTRL keys and press Z then M
and then enter ?

What does MR and MW mean ?

I use a PS/2 mouse too. It's a Logitech optical one.

Thanks

 

Hold them all down!!!!

Mouse reset, mouse work, sort of something Disney would think of?
