"You cannot cold boot a computer running on BIOS with a USB keyboard."

I don't quite understand this scenario. Cold booting is booting from the Off position, but how does one run 'on' the bios? I'm sure you aren't referring to not being able to use a USB keyboard at post to get in the bios since it won't communicate. Mine can as well do alot of modern usb keyboards.

Modern motherboards can use USB keyboards, it has nothing to do with your keyboard itself.

The issue is not that at all. The issue is trying to figure out what this means?... "You cannot cold boot a computer running on BIOS with a USB keyboard."?

I'm slightly ********, so if i'm looking for the fastest response time keyboard, I should be looking for a PS2 keyboard right?

keyboards like this that boast 1ms is a total lie? http://www.newegg.com/Product/Product.aspx?Item=N82E16823129002&Tpk=quickfire


thanks.

Depends.

When you say "slightly" is that ms or seconds?

The OCN guide is not ******** but it sure needs an update.

thanks.

Response time is the same as far as anyone can care. Any keyboard boasting about being fast is a marketing gimmick.

Only advantage to ps/2 is some keyboards only support NKRO over ps/2. Not all ps/2 boards have NKRO though.

I don't know why, but PS/2 has this feeling where it lag spikes randomly. (At least in my experiences, more prominent on mice)

I personally consider USB superior as long as its updating at at least 1000/100 or 10ms + 6KRO (OPINION)

Agreed.

The OCN Mechanical Keyboard Guide is woefully out of date.

It's 2012 people!
