I have a new 486 DX-66 and have found that when trying to install software
from either floppy drive, I often ran into problems.  It seemed that
even though I had "Inserted disk #2 in drive B:", the installation program
still detected disk 1.  To try to isolate the problem, I booted from a
"command.com" only floppy disk.  Typing DIR gave me the expected list of
files on drive A:, namely command.com.  However, putting a different floppy
into drive A: and doing a DIR revealed that the drive was not updated
(refreshed?); i.e. I still get only command.com - it hasn't realized that
I've switched floppies.  I tried this same procedure on my 486-33 and got
the expected results i.e. it gave me the correct directory of each diskette.
     My thought is that booting from a floppy like this eliminates a
problem with config.sys or autoexec.bat..  Also I don't see any connection
to the fact that it is a 486-66.  Has anyone any experience with such a
problem?
Thanks
