We are using a PC equipped with IBM Cyrix 486/50, VESA bus, Ethernet board 3com 3c509 and Windows 95. When we installed network software from Windows 95 setup we can not use floppy disk anymore. Any time we try to access a file in a floppy disk the computer crashes. It is not a problem of disk controller because we already tested 3 different controllers. If we start in DOS mode, the floppy disk drive works perfectly. Only when we are under Windows 95 with network software installed the problem appears. What can I modify in the setup to have both floppy disk and network working under Windows '95?
