hi, i have a problem with my pc...and it's not that easy to solve, i'd like to know, if any of you could help me. the problem is, that my ps' keyboard circuit is burnt, and i bought a USB (wireless) keyboard and mouse. i want to use the keyboard in dos, but i'm not able to. i know that i have to activate an option in the bios, but the problem is, since the ps is burnt, i'm not able to enter bios to activate the option to make the USB port work in dos.

know, i'd like to know if there's any way for me to solve the problem without having to buy a new motherboard.
i've already checked the motherboard's manual to see if there's any jumpers option to activate that, bue there was nothing.

please help me, it's urgente.
sorry about the mistakes...i'm portuguese....

Have you let the system board set for 24 hours with power off and unplugged from the wall power? The PS/2 keyboard/mouse often has a +5v protection circuit on better system boards, and it can "heal" and reset if the damage is not too bad.

Have you tried setting up a diskette with one of the USB keyboard drivers and seeing if you can get it to work that way.

Else you will either have to find a way to repair the board or buy another one, as there is no way to get into CMOS Setup without a working keyboard.

Thank you very much for trying to help me, it was very kind of your part. ;-)
I'm going to try to let it unplugged for 24 hours, to see what'll happen.
I've already thought if there is no way to enter the bios with another pc by LAN. Could that be possible? probably i'd have to access bios anyway to activate LAN.

I have a similar problem - a bad keyboard circuit or port on one of my pcs and no way to get into the bios. I was going to try buying a USB keyboard, but was wondering if it is worth trying that on older pc (AWARD BIOS v 4.51 with WIN98), as I don't know how to get at CMOS settings without a keyboard. Could I get at the settings through a LAN?
I will also try leaving it unplugged for 24 hours. Please let me know if that works for you.

Filipe,
I had a similar problem with a burned out ps2 keyboard and mouse circuit on my soyo board (See message above), and luckily I was able to fix it, but it took me the weekend to figure this out. I bought a USB wireless keyboard and it still didn't work just like you - had NO Keyboard found error. But then I tired something else. I installed a new hard drive as the primary master and moved the old hard drive into the slave setting. I rebooted with my WIN 98 SE boot diskette, and the computer recognized the new configuration (including the USB keyboard) and then I was able to adjust the BIOS settings to enable the USB keyboard, then do fdisk and format the new drive, reinstall the operating system and my programs and then copy the needed data files from the old drive which is now the slave. I had to reinstall all the device drivers (icluding new ones for USB devices)(had to get some updated ones off the web as this pc is from 1999). This was alot of work to do just to bypass the ps2 ports and get the USB ports working, but everything is working well again. I am not sure why it worked, but there may have been something set in the hard drive files that contributed to the problem of not recognizing the USB port or the pc might just have needed to see a new configuration with the hard drive change to be able to also recognize that the USB keyboard was new. I'm not saying that it will work for you mother board, but it worked for mine. You may be able to fool it into thinking there is a new config another way. If you do put in a new hard drive you may be able to use a utility that would allow you to copy everything from the slave drive to the new master so you don't have to reinstall the OS and programs. Good luck, I know how frustrating this problem is and I hope you find a solution that works for you.
