WINDOWS

Summary:

A FatalExit error 0x04ff "INT 3F handler unable to load segment" can

occur if the system is unable to load a code segment. 99 percent of

the time, this error occurs in real mode. The problem is that there is

a stack frame somewhere that has a fixed DS in it. This problem can

occur if an application switches to a fixed data segment and makes a

far call to the code segment, and the code segment cannot be

subsequently discarded.

This error can also occur if an .EXE file cannot be read (for example,

there is a bad disk sector on the disk).
