Windows will not fully load

I have an older computer on which Win98 is running. This system basically
crashed after an attempt to re-install a printer that was giving me a
problem. I have tried re-installing Win98 from the CD that came with my
IBM computer, but I get a message saying that I already have an upgraded
version of Win98 on my computer, and it will not re-install. Presumably,
this has something to do with my having installed the service packs for
Win98. I have run scandisk successfully. However, when I boot into Windows
safe mode, I get the "program has performed an illegal operation and will be
shut down" error message with the following details:

I have tried to create a FAT32 EBD by running FAT32EBD from the Windows 98
CD. However, when I get to the stage of "Insert diskette into A drive -
Warning: all info on diskette will be erased. Press ' Y 'to continue or any
other key to exit. " I enter ' Y ' and then I get into a loop where the
program just keeps asking if I want to continue.



I do not want to upgrade this computer to any higher Windows version right
now for a lot of complicated reasons. Reformatting is not an option,
because I have some very valuable data on this computer. Of course, I have
backups, but reconstructing the database would be a huge effort. Does
anyone have suggestions as to what I might do?

Thank you.
