    I'm trying to check that some old hardware works before putting it up for sale on eBay (anyone interested in parts of systems based on Pentium 60, Pentium 200MMX, Celeron 300A or Athlon XP 2000+ ?).

    In order to do so, I want to get the Celeron system working with Win98SE. To install it, I need to connect a CD-ROM drive. This is where I run into trouble.

    The DOS drivers recognise the CD-ROM drive and MSCDEX assigns drive letter R: I can even switch to drive R: But as soon as I attempt any kind of read operation (eg: dir r I get an error message (sorry, forgot the exact text, but it's NOT "invalid drive spec"). What's more, the light on the drive does not come on.

    I've tried this with two different CD-ROM drives using their own drivers (a 16x Goldstar CD and a 16x Samsung DVD) with the same result.

    I could really use some advice on how to trouble shoot this further without wasting my time.

    What I've done:
    - Device line in CONFIG.SYS
    - MSCDEX line in AUTOEXEC.BAT
    - Master jumper setting on IDE channel 2
    - Tried alternate IDE cable
    - Tried slave on IDE 2

    What I propose to try:
    - Slave on IDE 1
    - Something in the BIOS?
    - Connect drive to WinXP machine to see if it works at all.
    - Using the middle connector on the IDE cable
    - Using various switches to MSCDEX or the device line?
    - Master on IDE 1 (no HDD)
    - A simpler CD-ROM disc?
    - A different version of MSCDEX?
    - A Samsung DVD-R/W drive (would this even have DOS drivers?)

    As you can see, I've got a lot of ideas that I don't expect to have any effect.

    So which ones do you think are worth trying, and what haven't I thought of?

    Thanks hugely!

    Syntax MSCDEX /D:<driver_name> /M:<buffer_sector_cache> /E /L:R

    - driver_name should be the same file as the one in config.sys
    - you need to figure out your buffer settings
    - /E is used if you're using expanded memory
    - /L is used to define the drive letter for your drive, in your case you mentioned "R"

    You also need to have "lastdrive=Z" in your config.sys file

    typically it'll look like "lh c:\windows\command\mscdex.exe /d:mscdxx /m:100 /l:r"

    You can leave the cd rom drive as a slave.

    I hope this solves your problem.

    Load Ubuntu from CD - that'll test your hardware.

    cheers, Paul

    I'm not entirely sure how Ubuntu is going to help me... Inside joke, maybe?

    Anyway, the MSCDEX syntax I had was OK, but a good thought, since it's one of those things MS doesn't document very well.

    Turned out, opening my WinXP case and connecting the drives for testing was the right way to go.

    It seems, there's hardware problems with both drives (could be as simple as a dirty lens), so both are now at my local recycling centre.

    Luckily, I had a third drive, and it even worked better with Win98's automatic boot floppy's drivers than it did with Samsung's own!

    Feeling much better, now that this is all working!

    Thanks to those who thought they might be able to help, even if you didn't post.

    Ubuntu recognises most hardware and will run happily on old machines. If it won't load you have a boat anchor.

    cheers, Paul
