After installing Outlook 98 from the Internet install setup, the computer rebooted and gave the folling error:
While initializing device IOS:
Error: An I/O subsystem driver failed to load.
Either a file in the .iosubsys subdirectory is corrupt, or the system is low in memory.
How do I fix this? It boots in safe mode ok. I have no autoexec.bat or config.sys (renamed them even though they were empty).
