Model 60 is a PS/2, I think...
Good call, I must have not had my coffee yet! It is a System/2 not System/1.

If you don't change the dallas chip:
-The floppy drive will not work
-Every time you reboot the computer you will have to press F1 to bypass the configuration errors
-The system will boot only from ROM drive (using PC-DOS 4.0 and quad screen) and not from the operating system installed on the hard disk (forget the idea of using freedos)
The Dallas chip is not soldered to the motherboard, replacing it with a working one will not break the board.
Hi Nestor,
Also looking at the ribbon cable on the floppy drive, it appears as though PIN 1 is cut, but if I recall from when i had this system 20 years ago, I seem to remember it was like this on my old system too...
All the symptoms you describe are caused by the dead DS1287, but I think the drive motor should spin. I remember using a DD floppy disk to launch configur.exe and it gave a lot of read errors, but at least i could see the contents of the floppy with DIR command.
Maybe your floppy drive doesn't work (I have a Mitsubishi one that behaves like that)

You probably need to re-enter the settings in the BIOS to get those error codes to go away. I'm not familiar with that exact model, but either you need to press a key on the keyboard to enter the BIOS settings or you need an IBM reference disk for the 2011. This bootable disk allows you to access the BIOS settings.

And see if you can get into the BIOS by pressing the F1 or F2 keys.

The key board is not responding and there is a constant beeping sound.
Your keyboard is not working. The constant beeping sound is a clear signal. Inside the IBM PS/1 keyboard (Model M2) there is a controller board with two SMD electrolytic capacitors that tend to break down. You can open the keyboard, unsolder these capacitors and solder two new capacitors. Or you can use any standard PS/2 keyboard instead
That will make any 30X error dissapear. The other two should be gone when you run the CONFIGUR.EXE setup utility (the PS/1 BIOS SETUP application). It should be located in C:\DOS
What battery was inside it before you replaced it? I'd use the DS1287 instead of the DS12887. Although I think only one pin needs to be bent back on the 12887 to make it essentially a 1287. Then (until you fix it), use another PS/2 keyboard and see if you're greeted with C:\.

my P/S1 TYPE 2121 has ISA slots, is twenty years old and no change of battery. The keyboard has given up the ghost
