Hi again
Floppy Stuff
If we could get the floppy drive to co-operate, this is the standard method for running the diagnostics on your model. [It's too bad that your model is somewhat unique in its diagnostics, for many other models have bootable CD versions of the diagnostics available via download -- Alas, not so for the 7000].
When you created the Dell Diagnostic floppy diskette, did you double-click the I7K-394B.exe file, which began a process that self-extracted the files, and wrote them to your diskette, creating a bootable floppy diskette with the diagnostics? If not: create the diskette in exactly this way (use a fairly new floppy if you have one).
If yes: then you booted with the diskette, and received the "remove disks..." message? I'm thinking that what you are seeing is not a message from the Dell diagnostics - I'm thinking you are seeing a message from the Windows 98 Setup (that you started & aborted a few days ago) .. I think it's possible that your system isn't seeing the floppy at all. That message could be coming from Setup files still present on the C: drive from your interrupted Setup.
So let's try:
1) Enter Bios Setup, and double-check that the floppy is still set to be the first device in the Boot Order. Put the floppy first, the CD-ROM second, and the hard drive third. (Another thing: see if the date & time are OK = if not, let me know). Don't "Save Settings & Exit" yet.
2) Put the Dell Diagnostics diskette (already fully extracted) in the floppy drive
3) Put your Windows 98 CD in the CD-ROM drive.
4) Now select "Save Settings & Exit" to exit Bios Setup
5) Your computer will now boot either into the Dell Diagnostics, or from the CD-rom.
If the computer boots into the Dell Diagnostics:
1) Follow the instructions, and run full tests.
If the computer boots from the Windows 98 CD-ROM:
1) Select "Start computer with CD-Rom support" (Yes, this is real DOS).
2) From the resulting command prompt, type
A:
3) If you are then able to see an
A:> prompt, type
dir/p
4) You should see the files on the Dell diskette list, one page at a time. I'm not sure which executable starts the diagnostics, there might be just a few listed: if you'd like, copy the executables down, post the list here, & I'll suggest which is likely to be the one to start the diagnostics. This is an unorthodox method of starting them= I'm not sure if it will work or not. One tip: don't try to start the diagnostics by typing I7K-394B.exe -- that is only the name of the zipped download, & won't start the tests.
If you can't get to an A:> prompt, the drive, or it's controller, has likely failed.

All this is only if we insist on trying the Dell Diagnostics. Actually, since we know the computer can boot from the CD, we could simply use different diagnostic tools. If you have a friend with broadband (or have broadband yourself, and another computer to use), you can try making an "Ultimate Boot CD" ---
http://www.ultimatebootcd.com/ --- This is a bootable CD that has many diagnostic tools already on it - including MemTest86+ to test the memory, and most major hard drive manufacturer's diagnostics tools -- if you don't know the brand of your Inspiron's hard drive, the UBCD has the DOS version of ASTRA on it, which can try to detect your hard drive (and other system components as well). All the details about making the UBCD and how to use it are on their website.
That will be the way to go if the floppy drive is just dead.
See if this gets the tests going - I'm definitely interested to see what they tell us about the health of the hard drive.
You're hanging in there pretty well, I'd say!
