Dell PIII, 384 MB RAM, 20 GB HD.
Following error starting Win 98SE after custom install Office 2000 Premium:
While initializing device IOS:
Error: An I/O subsystem driver failed to load.
Either a file in the .\iosubsys directory is corrupt or system low in memory.

System freezes. Can run only in Safe Mode w/o CD support.

How do I fix?

My advice would be to download a program that can check your RAM and make sure everything is functioning correctly there. I don't have much knowledge of the I/O subsystem drivers, but if the RAM checks out OK, I would suggest first reinstalling Office (even though you just installed it), and if that doesn't work, then reinstalling 98SE. But don't reinstall the OS without getting some more info on I/O subsystems. There may be a fix for that. Hope this helps!

the memory area required for the i/o subsystem has run out of memory. you can fix this easily by locating the [vcache] line in your win.ini file and enter the following...

[vcache]
maxfilesize=1024

if the setting already exists, reduce the value by a factor of 16 (1024 = 64 * 16).

hope this helps...
