Specs: Windows 98, Pentium II, 233 MHz, 64 M
Greetings to all..
I´ve been doing some reserch over the internet in order to find a way out of my problem and I came across this forum. You seem to know a lot, so here is my problem:
I´ve got this kind of old computer (Pentium II, 233 MHz, 64 MB RAM, with Windows 98), which was working perfectly until recently.
I had to change the battery and my BIOS was reset.
Now when I start it up I have no mouse and no keyboard!!! It´s useless!
I´ve made some changes in the BIOS to try and get it working, (Enable/Disable PS2 mouse port, Enable/Disable Serial ports...all kinds of combinations)...but nothing...
oh! I almost forget, the motherboard has an Intel 440 chipset and the BIOS is "AMIBIOS" Verion 1.18.
Thanks in advance, I really hope you can help me!

Regards,

.: Ashley :.

How do you make changes in the BIOS if your keyboard doesn't work? What happens when you boot into safe mode?

Hi,
you are right Jam, I forgot to specify that the keyboard and mouse dont work in Windows.
The Keyboard works properly in DOS (in fact, yesterday, I´ve re-installed Windows 98 thinking that I had messed something up with the drivers )
I tried booting into safe mode and both devices work properly!!
I suppose this means there must be something wrong in the BIOS? Right?
Thanks for your concern Jam! I appreciate your help!

"Now when I start it up I have no mouse and no keyboard!!! "

""I´ve made some changes in the BIOS to try and get it working, (Enable/Disable PS2 mouse port, Enable/Disable Serial ports...all kinds of combinations)...but nothing..."

So how did you get into the bios then?
.....

When and where do you have no mouse or keyboard?

If they are both USB connected, probably neither will work in the bios with default bios settings, and probably neither will wake up the computer - you have to use a PS/2 keyboard, and enable Legacy USB support, or similar, in the bios Setup, which is often disabled by default. In some older bioses you must enable the USB controller, and also assign a IRQ for USB - they may be disabled by default.
To get the wake on features to work for the mouse and the keyboard of any type, you may have to change default wake on settings, which may be disabled by default, and ACPI or APM must be on in the bios. Not many old bioses can use a mouse in the bios, and if they can often it must be PS/2 or serial connected.
......

In Windows, look in Device Manager - do you see any unknown devices, or other entries with a yellow ? or a red X, or are there missing entries?
.....

You could have a faulty power supply and that is what is wrong - e.g. USB devices will not work if the +5v is too low or not there; neither will floppy drives and CD drives for that matter.

Check your PS.
See response 4 in this:
http://www.computing.net/hardware/w...
.....

"BIOS is "AMIBIOS" Verion 1.18"

If that is on the bios chip it's probably useless.
If that is displayed on the first screen as you boot, version 1.18 doesn't reveal enough if we don't know what mboard make and model you have.

If you DO know your mboard brand, model, or mboard version or revision number, or your brand name system model number,
tell us what it is.

If you DO NOT know your mboard brand, model, or mboard version or revision number, or your brand name system model number, we need more info.
......

If the motherboard is in a working system, we need your bios string to be able to identify your mboard and/or computer.

Go here, download BIOS AGENT.
Run BIOS AGENT
- here's the link that downloads Bios Agent
http://download.esupport.com/biosag...

Tell us everything Bios Agent finds, and include any dashes, etc.
...

Did you REMOVE the power to the mboard while you fiddling around in the case? ATX mboards are always powering ATX mboards in some places even when Windows is Shut Down or in Standby or Hibernate modes. If all you did was change the mboard battery you probably didn't harm anything, but if you unplugged or plugged in anything connected to the mboard with the AC still on, you can damage the mboard or anything connected to it.

Did you by any chance change any ram while you were changing the battery? The 440LX chipset is very picky about which ram you use.

Slow on the type again. When I started response 3 there were no reply posts.

Since the mouse and keybord do not work in Windows normal mode...

The bios string is usually a long string of numbers/letters at the bottom of the first black screen as you boot your computer, often beginning with a date - usually you can press the Pause key to read it and copy it down. Press any key but Pause to continue booting, or press Enter.

Post that bios string here, and include any dashes, etc.
Please make sure you copied it right. Most Award and AMI Bios strings do not have spaces.

....

"I´ve re-installed Windows 98 ..."

Did you install it from scratch, or did you do an "overtop" Setup - install it in the same C:\Windows directory. The latter won't always fix problems.

"I tried booting into safe mode and both devices work properly!!
I suppose this means there must be something wrong in the BIOS? Right?"

More likely there is a problem in Windows in normal mode.

You could try loading bios defaults in the bios. Sometimes that works after you have removed the battery or cleared the cmos when nothing else helps.

Yeah, are they USB or PS/2?

Make sure they're in the proper sockets, although most mouse/KB sockets aren't interchangable.

If PS/2 go into device manager while in safe mode and delete the mouse and KB entries. Delete the KB first as once you delete the mouse it will no longer work. Then restart the computer.

"...go into device manager while in safe mode and delete the mouse and KB entries. Delete the KB first as once you delete the mouse it will no longer work. Then restart the computer."

You will get a message asking if you want to Restart after Removing the keyboard - don't Restart yet - the keyboard will still work.
After you remove the mouse, press the Alt-Ctrl-Del keys at the same time, use Tab to toggle the highlighted key to Shut Down, press Enter.

Thank you so much for your answer!

I forgot to specify that the keyboard and mouse dont work within Windows. The Keyboard works properly in DOS (in fact, yesterday, I´ve re-installed Windows 98 thinking that I had messed something up with the drivers )

When I boot into safe mode both devices work properly.

-> In safe mode in Windows 98 I get a few yellow question marks on some devices , but I guess that´s probably because I´ve reinstalled the OS and some drivers need to be installed... the entries for the mouse and keyboard seem normal and functioning

->I have a serial Keyboard and a PS2 mouse (I´ve tried a serial mouse as well but didnt work)

-> I´ll see if I can find more information on the motherboard, hopefully it will be usefull to you (cant do the Bios Agent thing cause the mother is on the "dead " computer) =(

-> Didnt touch any cables inside the case. I´ve replaced the battery normaly.

-> I havent removed the RAMs.. wouldnt dare to .. !!haha

And I want to add this strange piece of information: During one of the reboots , after making some changes in the BIOS (I changed the option "Plug and Play Aware OS" to "No") I´ve entered Windows Normal Mode and I was able to type 1 letter of the logon password... then the keyboard was dead again...
Strange, huh? I wasnt able to do it again...
I appreciate your help.

->Great! I´ll be back with this information!

"Did you install it from scratch, or did you do an "overtop" Setup - install it in the same C:\Windows directory. The latter won't always fix problems."

-> I´ve installed windows from scratch!


Thanks to all.. I´ll remove the entries for the mouse and Keyboard and get back to you!

"In safe mode in Windows 98 I get a few yellow question marks on some devices ..."

Tell us exactly what has yellow ?'s beside them.

"I have a serial Keyboard and a PS2 mouse (I´ve tried a serial mouse as well but didnt work)"

Serial keyboard?
The keyboard either has a PS/2 connection the same size as a PS/2 mouse, or if you have an older keyboard, a larger about 3/4" round DIN connector, which would have to have an adapter to the PS/2 port for the keyboard on your computer.


The IRQ for the serial port must be available for the Com port the mouse is plugged into, and the Com port must be enabled in the bios.
E.g. internal dial up modems often use IRQ 3 or 4, the same as a serial mouse uses, and one Com port may be disabled in the bios to make the IRQ available to the modem.

"....(I changed the option "Plug and Play Aware OS" to "No") I´ve entered Windows Normal Mode and I was able to type 1 letter of the logon password... then the keyboard was dead again..."

Sometimes toggling Plug and Play Aware OS to No when it was Yes, or visa versa, will help, because the IRQ's may be assigned to devices differently, and eliminate a conflict in one mode.

It is very common for wires inside the sheath of the cord on a keyboard or mouse to break, often right where they enter it - at first the keyboard or mouse will work intermittantly while the wire insulation is still intact and when the wires ends are touching, later the insulation will break and the wire ends will no longer touch and at least one function won't work. Windows may not properly recognize the keyboard or mouse in either case. If the former is your case, wiggling the cord near where it enters the keyboard or more may get it to work intermittantly.
Try the keyboard and mouse from your working computer.

Hi, Im back with news...
I have been able to retrieve the information you have requested. According to the number i read on my screen while the system was booting, i found out that the motherboard is a PcChips M715 Model.
Anyways, the number is:
61-0701-000715-00101111-071595-m715-1440l000-h
I´ve downloaded the manual but its hard for me to understand.. if you have any tips, they are more than welcome.

Thanks

I strongly suspect your problem with the keyboard is because of broken wires within the sheath of the cord.
If you can obtain and try another keyboard, do that. You can use a PS/2 (male) connected keyboard if you use an adapter (PS/2 female to DIN male)to convert it to the larger round DIN keyboard port (DIN female) on the mboard, or used keyboards with the larger DIN connector are cheap.

Bios Setup
How to get into the Bios Setup:
When you see
"Hit <Del> key if you you want to run Setup"
press the Del key.

Advanced Setup

PS/2 Mouse Support - Enabled
The default is probably Enabled.
If this has been Disabled and you are using a PS/2 mouse, that mouse will not work.

Chipset Setup -

Onboard USB Function - Enabled
The default is probably Disabled.
If this has been Disabled no USB device will work when connected to the wiring adapter with USB ports in it that connects to the mboard USB headers.

USB Function for Dos - Disabled ?
This may be Disabled by default. This is probably equivalent to USB Legacy support. If this is Disabled a USB keyboard will not work to get into the bios Setup, but it will work once Windows starts to load; and a USB mouse will not work in the bios Setup (if it even can), but it will work once Windows starts to load; a USB keyboard or mouse will not wake up the computer even if other bios settings necessary for wake to work are correct.

There is no setting to disable a keyboard, so it should always work to get into the bios Setup.
You have the keyboard port type that uses the larger about 3/4" round DIN connector.

Peripheral Setup

Physical serial port wiring adapters connect to the Com 1 header on the mboard for Serial Port 1, and to the Com 2 header on the mboard for Serial Port 2.

Onboard Serial Port 1 - select I/O port - default usually I/O port 3F8, IRQ 4

Onboard Serial Port 2 - select I/O port -default usually I/O port 3F8, IRQ 3

IRQ 3 is often used by internal dial-up modems and Serial Port 2 has to be disabled in that case.

Serial Port 2 Mode
- Normal - usually the default - resources are assigned to the physical serial port.
- IrDA/ASKIR - serial port 2 resources are redirected to support infrared function instead of the the physical serial port

- Duplex Mode - or Serial Port 2 - applies only to IrDA/ASKIR?

Parallel Port Mode
- usually Normal is the default
- usually EPP is best if you have a printer or scanner connected to it.

Thanks Tubesandwires! I´ll try the settings you advice.
I must say I really don´t think there is a problem with the Keyboard cause it works perfectly before Windows starts up.
And both, the mouse and keyboard, work properly in Windows Safe Mode.
I suspect it may be something I´ve messed up with the IRQs and I/O ports, so I´ll try what you suggest.
I´ll be back with more news!

Thanks again to all for your help!

Alright then, don't try another mouse or keyboard for the time being, although you may be able to get a usb or serial mouse to work, or a USB keyboard.

You said in your first post "I had to change the battery and my BIOS was reset."

All your problems started with that, so the bios settings are most likely where your problem lies.

Another thing - sometimes IRQ assignments get shifted when you remove the mboard battery or clear the cmos settings (the user changeable part of the bios) by moving a jumper on the mboard, and something that worked before no longer works or is in conflict with something else. Take a look in Safe mode to see if all the devices that worked before are still working. If some aren't, or in any case if you're not sure, you could try removing all your cards making note of which slot they were installed in - the keyboard and mouse should then work fine - and installing the cards in the same slots they were in one by one until the keyboard and mouse no longer work and you will know what the device your problem is about and we can help you with that.
REMOVE the AC power to your case when installing or removing the cards.

You could also try toggling PNP aware OS on and off each time. In theory PNP is handled by Windows better thaan the bios handles it, but sometimes that's not the case.
.....

For the next time, before you remove the mboard battery, or clear the cmos settings by moving a jumper on the mboard - copy down all the bios settings that are not set to defaults - consult you mboard manual - often the default bios settings are specified in the manual.
