Re: Bios does not find PS2 keyboard/mouse
Did you go into the BIOS and set it to recognize the USB Keyboard after you reset the BIOS? Is windows not noticing it or the BIOS. You stated that it recognized the USB keyboard and then said that it did not. What does all of this mean? USB keyboard does not activate "del" setup.
If it does not work, it is because you reset the BIOS and did not change the settings back for the USB keyboard.

Try using a PS2 mouse and PS2 keyboard. It may be that your USB ports have lost their setup (assuming that you are using USB or wireless mouse and keyboard). If the PS2 hardware works fine, check that your USB ports are enabled in the BIOS, then check your device drivers in Windows to see that the USB hardware is recognized.
Shut down the computer and disconnect the USB keyboard. Connect a PS/2 keyboard to the PS/2 connector port on the rear of the computer. Enter bios restart your computer you will see a certain to press to enter set up usually the Delete or the F2 key this will vary depending on you computer and bios. Wait for the main BIOS setup screen to appear. Press the right or left arrow keys to move the cursor to the "Advanced" or "Advanced Settings" menu option. Press the "Enter" key. Move the cursor to the "Integrated Peripherals" or "Peripheral Configuration" menu option. Press the "Enter" key. Press the down-arrow key to navigate to the "USB Controllers" option. Press the "+" or "-" key to change the menu option to "Enabled." Move the cursor to the "USB Legacy Support" or "USB Legacy Function" field. Press the "+" key repeatedly until the value option changes to "Enabled." Press the "F10" key to save changes to the BIOS settings and exit the setup utility. Wait until the computer begins to restart and then press the power button and hold it for approximately four or five seconds. The computer shuts down completely. Unplug the PS/2 keyboard from the computer and set it aside. Reconnect the USB keyboard restart the computer. As soon as you see the initial boot screen, tap the "Delete" key several times and wait for the BIOS setup screen to appear. If you are able to access the BIOS setup screen with the USB keyboard, USB support is active in the BIOS.
Enable PS2 & USB in BIOS You can enable PS2 and USB settings in BIOS by entering the BIOS setup screen when the computer boots. You will need to changes to the appropriate settings in this screen. The exact procedures vary by system, but there are a few common methods that may work if the motherboard manual is not available for guidance. The general procedure is the same for any modern computer system, but the menu arrangement and keystrokes to enter the setup program can vary greatly from one machine to the next. Power on or restart the computer and watch the initial boot screen to find the keystroke required to enter BIOS setup. This is often shown at the bottom of the screen. Typical keystrokes include pressing the "F1," "F2," "F9," "F10" or "Del" key. Press this key when the prompt appears on the screen. You can find the proper key in the computer's motherboard manual or on the website of the motherboard or computer manufacturer. Enter the BIOS setup screen and look for the "Advanced" or "Onboard Device Configuration" menu. Use the arrows to select your choice and press "Enter." Change the settings for the PS2 port by moving the menu choice to the "PS2" setting. Press "Enter" to bring up a smaller menu with the options to enable or disable the PS2 ports. Select "Enabled." You can also use the arrow keys or the plus key to change the current selection from "Disabled" to "Enabled" in order to enable the PS2 port. Change the settings for the USB port by moving the menu choice to the "USB" setting. Press "Enter" to bring up a smaller menu with options to enable or disable the USB ports. Select "Enabled." Alternatively, use the arrow keys or the plus key to change the current selection from "Disabled" to "Enabled" in order to enable the USB port. Save the settings and exit by pressing "F10" or using the "Esc" key to back out of the current menu. Choose to save and exit from the main menu if needed. Follow any additional instructions on the screen to save or navigate the menus. Hope this helps.
It appears that you have an IBM desktop whose BIOS isn't capable of booting off of a USB keyboard and mouse device. Older computers used to require that a PS2 mouse and keyboard be attached before booting, to prevent you from booting a machine without any way of controlling it. You have 3 options:
1. leave the corded mouse and keyboard attached and never use them
2. update the BIOS for your desktop to the newest one in hopes that the updated BIOS will allow for USB mouse and keyboard operation
3. go to a computer store and get a PS2 to USB converter/adapter. They're small and relatively inexpensive. It plugs into the PS2 port, and makes your computer think that there's a PS2 device connected, when it's actually a USB device.
Assuming you have checked in setup that the PS2 is turned on the other option is to re-flash the bios .
At some time someone switched the mouse and keyboard and started up the computer this can cause you to need to re-flash the bios most likely the keyboard chip needs to be replaced sorry to bring bad news .
Dell seems to have this problem yet the USB works is good where most modern keyboards and mouse are USB.
Purple is Keyboard if not color coded the closest to the outer side of case is the keyboard.
Good luck hope this helps you
PS. You may try setting the jumper pins to default the main board back to factory defaults then remove the jumper pin and leave off for first boot .When doing this be aware not to have the power cables connected to the server remove all power cords and the monitor . Prior to doing the first power up plug in the PS2 keyboard only then the monitor. Cross you fingers If you lucky your PS2 port’s will be working again if so shut down re install the jumper pin install the PS2 mouse.
Could be a problem with your system BIOS, enter the setup while your computer is booting (before it gets to windows) by hitting the F12 key probably. Make sure that the boot order is HDD first, not something else.
Often times this happens when using a USB keyboard / Mouse.
Or when using a USB keyboard through a PS/2 Converter.
Try using a PS/2 Keyboard if available (Small Round connector with a small amount of pins, similar to a S-Video connector.)
Also. Access your BIOS settings and assure that you have Legacy USB keyboard support. Depending on your computer the BIOS / Setup Menu / Options Menu/ Etc. can be accessed by pressing the following key during boot: F1 F2 ESC DEL F12
Let us know your setup(KB and Mouse Port type), and if you have any other issues.
I do not recall one ever doing that either. Why couldn't you get into the BIOS to check to make sure that the settings are on for USB. I do not understand why you can't get into the BIOS. That is the way that I have always done it. Strange how it can boot into windows. You must have the settings set so it will boot up without user name or password. I have been doing computers for six plus years and I do not understand that one either. I am exhausted with solutions at this point. I am sure that is not the answer you wanted but I am as stumped as you are.
