  • Take a good look at the picture...
    Seeing as how Microsoft doesn't tell you where to find any of the files they listed, I'll see if I can get any help here.

    I have an extremely old Windows 98 IBM Thinkpad 600 laptop. (It pretty much stopped working after a 192 error message, but that's another story.)
    Windows 98 started to have these problems when I booted it up:
    • Every 5 minutes Explorer had an "Illeagle Operation"
    • Whenever I used Windows Explorer (to look at folders) it would remain blank and not display anything.

    So now I am going to try and reinstall Windows 98, since I don't have anything to loose on the laptop. So here I am in MS - DOS mode, and I'm trying to access the CD ROM drive in my laptop. I know that the drive letter should be D:, but when I type that in, MD DOS always replies, "Invalid Drive specification". I even tried what someone had reccomended earlyer by going one letter down to E:, but that still didn't work.

    So if anyone has any answers to this problem, that would be greatly appreciated. (Not to get off topic, but if anyone can explain why I keep getting a 192 error when booting up my laptop, that would be great.)

    P.S. I can only use one drive at a time; floppy or CD. I have to shut down my laptop and insert the drive to be able to use it.

    Thanks in Advance!

        Well, I already knew it was a fan error, but the fan works prefectly well.

          1. Measure the voltage of the backup battery. If the
          voltage is not correct, replace the backup battery.
          2. Fan
          3. System board

          Did you bother to check anything besides the fan? Battery voltage? Diagnostic?

            Yes, I did read it.

            I'm very certain it isn't the fan.
            Could be the system board.
            How do you measure the voltage?

              Remove the battery and test with a VOM (volt-ohm meter).

                Well, I apologize for asking so many questions, but can I use that on a normally battery tester? I'm pretty sure I don't have one of the things that you suggested.

                  Depends on the battery tester - If has a digital readout and is capable of testing the correct voltage range. The voltage should be +/-5% of the battery's rated voltage. Slightly higher is always better than under.

                    Well, the batter tester is a hang-on-the-wall battery holder, but it comes with a little tester. I'm afraid that it's only meant to test batteries such as 9 volts, AAs, etc.

                    Anyways, do you think I should just buy a new battery?

                      You will need to use a bootdisk for Win98SE with CDRom support to do so...DLoad from bootdisk.com..

                      At the A: prompt after booting type D: and hit Enter. Then type setup and hit Enter and the Win98 setup should start.
                      ( Some bootdisks make R: the CDRom drive so if D: doesn't run use the above instructions with "R:"...)

                        Remember, I can only use one drive at a time

                        Anyways, I think I fixed the problem by reformatting my hard drive, but I'll post again if it isn't fixed.

                          Once again, I can't access D: without it giving me an "Invalid drive specification" error. Second, I can't even have both floppy and CD in my laptop at the same time.

                          P.S. I have also tried A-Z in drive letters. Same thing.
