Hello Everyone :flowers:

I am having a lot of problems using my keyboard & mouse when I boot using DOS or Linux utilities like the Ultimate Boot CD, GParted Live CD, even my SeaTools for DOS (I have a Segate HD).

For example, when I boot from the SeaTools for DOS floppy, I am presented with the Lisence agreement, but I cannot use the keyboard or my mouse to get past this screen to select "Agree" or "Disagree". Many other boot CD's and floppies have similar problems when using USB input devices.

A lot of these utilities have generic drivers for mice & keyboards that are PS/2 like mouse.com, keyboard.sys, etc. However, DELL computers only have USB ports. :trumpet:

Also, I do NOT have USB legacy support option in the BIOS menu...only a USB controller which I can enable or disable. I have the latest BIOS firmware installed.

QUESTION

I have a PS/2 keyboard & mouse stashed away (they both work, I think). If I purchased an adaptor that can plug into a USB port and contain a female PS/2 port on the other end and I plugged in a PS/2 keyboard or mouse, would the boot CD see this as a PS/2 device or still as a USB device? In other words, would the adaptor "trick" the BIOS into thinking that I'm using a real PS/2 port in the comp or would it see it as a USB port with an adaptor?

Hopefully, I've made my question clear. Any help would be very much appreciated. :thumbsup:

I assume you're referring to one of these: http://www.cablestogo.com
Hopefully there is an option in the BIOS:

The one thing I noticed in the article is if you ever decide to flash the BIOS, be sure to set them back to disabled

Yes, this is what I'm talking about. :thumbsup:

So....if I plug this adaptor into a USB port and attach a PS/2 keyboard & mouse on the other end, will my BIOS see these devices as real PS/2 or as USB??

Hmm... that's a noodle scratcher.

I know that the reverse will work, that is a USB to PS/2 adapter being recognized, but I don't know about PS/2 to USB. My gut instinct says no, because it's still a USB connection. I spent the last 20 minutes or so trying to find info about this, but it seems you're one of the first people to ask that question.

I'd say talk to Dell. They may have a special way to make it work or may even send you a free adapter.

If you don't have legacy support for usb in bios and no ps2 ports then how do you access bios and make any changes?

No. Try not. Do... or do not. There is no try.
