I can't get my USB keyboard to work in BIOS.

I have an Asus VIA K8T800 motherboard.
I have tried 2 different USB keyboards.
Of course a PS/2 keyboard works but I would like to use the USB. I have also tried a USB to PS/2 adapter and that doesn't work either.

I have read up on this a bit and found that I need to turn on my 'USB Legecy' (haven't checked this yet) but they also state if this option is disabled the keyboard would not work in saft mode either which it does work in safe mode just fine.

I can use my "DEL" key to get into the BIOS.
I can also use the "F8" key to get to the Windows menu but once I get into the BIOS the arrow keys do not work to do anything.

Thanks for any help,
Debbie

"I have also tried a USB to PS/2 adapter and that doesn't work either."

The keyboard has to be a combo type that is meant to be used with either PS/2 or USB - if it isn't an adapter cannot work because the necessary circuits are nt present. If the keyboard did not come with an adapter wnen it was new it is not a combo keyboard.

You need to connect a PS/2 keyboard, go into the bios, turn on the Legacy USB support, save settings, then the USB keyboard will work in the bios.

"...they also state if this option is disabled the keyboard would not work in saft mode either"...

I've never heard that one - once Windows loads in whatever mode, it recognizes a USB keyboard or mouse, if the mboard has the USB capability.

I did what you said.
Connected a PS/2 keyboard, went into my BIOS and the 'USB legecy' was set to 'Auto'. I changed this to 'Enable', saved the settings, powered down and reconnected my USB keyboard. Yes I disconnected the PS/2 keyboard.

Still didn't work.

I could tell it wasn't going to when I first clicked ont he 'Del' key to go into the BIOS.
It goes in but when I did that on the PS/2 keyboard it reacted right away.

Thanks,
Debbie

Some BIOSes have a setting "Enable USB Keyboard Support." If you're lucky, yours does.

"If it ain't broke, upgrade anyway."

Are you SURE you saved bios settings after setting Legacy USB to Enabled? Actually it should work set to Auto as well.

Did you try both USB keyboards?

How old are the USB keyboards?


What USB port did you have the keyboard plugged into?
There are 4 USB ports (2 pairs) built into the mboard - and 4 more (2 more pairs) available via adapters from mboard headers that would be in (a) card slot space(s) on the back of the case if present, or a pair could be connected on the case at the front.

Take a look in your bios Setup again.

"Asus VIA K8T800" can be either
Asus K8V-X SE or Asus K8V-X .
I looked at the K8V-X SE manual.


Advanced - USB Configuration

USB 1.1 Ports Configuration - default is USB 8 ports

If that isn't set to 8, change it to 8, even if you don't have all 8 physical USB ports.
The keyboards are probably USB 1.1 compatible, but not necessarily USB 2.0 compatible, so any USB ports it is plugged into should have USB 1.1 available.

Remote possibilities:

Some keyboards have special purpose buttons that must be pressed to activate certain functions. If the USB keyboards have special purpose buttons, take a look at any documents or manuals for the USB keyboards. e.g. I have a second hand one that has a button that must be pressed to activate the F1 thru F12 key recognition. Someone got rid of it, probably either because they didn't like having to to that, or they thought the keyboard was no good because they weren't aware of that.

A lot of features mentioned in the K8V-X SE manual require that your power supply have a rating of at least 1A (1 amp; 1000 ma) +5VSB - if your power supply has a rating of less than that, that may have something to do with your problem.

Very good points

It is the K8V-X SE.

Did you try both USB keyboards? No only one of them. Since they both acted the same I fugured....

How old are the USB keyboards? Both keyboards are exactly alike and one of them is brand new.

I have tried a couple of the ports.
This MB has 4 onboard. I can try the others.

Like you mentioned though. I will make sure the enabling the USB legecy save or not.

I will also look to see if the Ports Configuration is set to USB 8

Also about the extra button on the keyboard. I think it has some so I will also try them.

I'm at work right now so later tonight I will look into this more and let you know the results.

Thanks,
Debbie
