You have to have a setup disk in order to re-configure the CMOS on that machine.
I'll try to find it for you on the web.

khemicals,
Heres the link that should get you going:
http://www.pc.ibm.com/cgi-bin/searchftp?bool=all&action=string&str=8570
Let me know if you need anything else,
Ralph

I should be able to try that at the school in a few days. Thank you for your help

I tried you suggestion and got both fo th files at that url. The one is the reference disk which i already had, and the other is a fCMOS update. However, I read the readme that came with the update and it said to use the reference disk to boot... when i have the refrrence disk in the drive it won't boot, says its not a system disk, however it did boot the other 5 ps/2 computers that are identical to it. so, the disk is still good. I still get the same 161 and 163 errors that i received before. and when i put in a dos boot disk it doesn't boot it either. Any suggestions?
Thanks for the past help rmarotta

khemicals,
I'm not familiar with the error codes but it sounds like a bad floppy drive.  Try cleaning it.  Or, can you temporarily swap a drive with a known good one?
Ralph

I am gonna search out the error codes first

If i remember rigth, press F1 (or F10) when u turn on the power, to enter the bios-setup

Satto

The explanation of your error codes are:

161 - Low CMOS battery
163 - Invalid Time and/or date

Pretty much the errors one would expect after reseting the CMOS
(I just *love* how IBM makes their error messages SO descriptive, whats wrong with verbose error messages.)
Your IBM does not have a button you can press to enter into the CMOS setup.  All the setup of the CMOS is done through Setup files that are stored on floppy, or on the hard drive.

<><><><>>><><><>
Side Note:

The IBM CMOS setup utility works the same as the COMPAQ's,  It requires software that is loaded on the Hard Drive, or Floppy in order to configure the CMOS, (this is true even for the new computers).

The software is generally saved on an *invisible* 3mb partition that is placed on the boot sector of your hard drive.  If the software is present, then it will allow you to press F10 to enter the CMOS setup utility.
<><><><><>>><>><><

Anyway.

One thing you *could* try is to swap the floppy drive from one of your other computers.

If that does not work, then I've got some bad news for you, friend...... 8o(

I am going to assume that you are trying to boot from a 1.44mb 3.5" floppy drive? Correct?

Does that machine have a 1.2mb 5.25" floppy installed on it?
I'm sure it did, at one point...

Well,

When you reset the CMOS by removing the battery, it reset the default floppy drive setting,  so your bios is now defaulting to a 1.2 mb 5.25" floppy drive for the A drive and therefore will not recognise the boot sector on your floppy disk.

Your only option would be to attach a 1.2mb 5.25" drive, and try booting from that.
(Have your utilities placed on a 5.25" floppy first)

There's your answer, my friend!

JRHelgeson

the computer never had a 5.25 drive as there isn't a blanking slot on the front wide enough for a 5.25 drive... all the slots... 2 i believe... are for 3.5 drives

oh... just in case i am gonna try two things tomorrow assuming i have time to work with that machine.... i will first try to make a 720 K floppy disk and pray that it just defaults to the 720k setting, make sure that all connections between battery and other connections to the battery are proper, and then at last try a known working ibm floppy... i'll let you all know how this goes for now... however i am still open for help
-david

1 thing more u can try, if u no a friend who has a IBM to, and still have the software on his
harddisk, try to swap it, and enter the setup.

Satto

i will add that to my list... btw.. i have 6 ibm ps/2's that i am working with so i don't need a friend.. even tho i have them :)... this is for volunteer work that i do at my high school and i already have 5 of the 6 up and runnign.... just this darn last one... these are donations from columbia gas in norwalk ohio (plug if they see it.. thx) and they are gonna be used in our keyboarding lab to teach typing.... 386's work good for that

rmarotta.... post a bogus answer... you were the first to mention a possible bad floppy drive and that was it... i switched drives today and all went well... now if i could only find a dirt cheap replacement.....????
thanks all
-khemicals

What kind of drive can you put into these old PS/2's???  I tried to remove the old drive but I can't even do that!!!

What did IBM do?  Use rivets or something!!!???

When IBM came out with the PS/2, they intentionally made it proprietary.
They didn't mean to make it easy for you interchange parts from other vendors.
Today, they make good objects to keep your boat from drifting around in the wind. (If the boat's not too big!)

Ralph

Where do I get the floppy for this thing and how do I remove the old one.  I think I bent the front cover trying to wrestle the darn thing out with a screwdriver.

real trouble now since my client needs to do his accounting.

Check the links I have posted in the above comments.
I can't help with thr drive removal, but it seems that I've seen torx screws used in IBM equipment before........
