Have you ever been puzzled by some CPU fault as to why it occurred, that is, why did the CPU think there was a problem? If so, this feature is for you. Whenever 386SWAT is called on the difficult to figure out CPU faults (TSS Fault, Stack Fault, GP Fault, or Page Fault), the Autofault feature attempts to determine why and to present a short prose description of the cause. The description is displayed in the lower lefthand corner of the screen. Pressing a key causes the message to disappear. To display it again (up to the time another fault occurs), press s-F4.
This feature is implemented for GP, TSS, and Page Faults, although they all could use more tweaking.
