I just did the upgrade to 2.75 and DOS 3.3 from Wyse. Unless your problem
is that the installation disks are 1.44M, I don't think the ROM upgrade is
going to solve your problem. Accessing 1.44M floppies is about all that the
ROM upgrade has that is significant. The DOS upgrade has a number of fixes
and improvements that are also probobly covered by DOS 4.01. I'd look
elsewhere for your problem. Perhaps if you gave more details about the
media, hardware you have installed, what Windows files actually make it to
disk, etc. someone will have a brilliant idea for you.
