buglist3.00 fixlist3.10

Summary:

PROBLEM ID: WIN9012019

SYMPTOMS

After an MS-DOS critical error has occurred in Windows (for

example, the system error "Cannot read from drive A:"), calls to

return extended error information, such as MS-DOS Interrupt 21H

function 59H or the C run-time function getexterr, return the value

53H (Interrupt 24H failure) rather than the error code for the

critical error.

CAUSE

Windows does not save the original error code to return to the

application.

STATUS

Microsoft has confirmed this to be a problem in Windows version

3.0. This problem was corrected in Windows version 3.1.
