To: djgpp AT delorie DOT com DJ-Gateway: from newsgroup comp.os.msdos.djgpp Reply-To: djgpp AT delorie DOT com How can DJGPP's FSDB (full screen debugger) read the descriptor tables? I mean when you press alt-g or alt-i. I want my own program to display stuff from them, but doing a sidt/sgdt to a struct { ushort limit; ulong address; } and the referring to the address just crashes under Win98. Well, that's what I expected, since those tables are (should be?) protected by the OS, and are probably mapped differently anyway. So how does FSDB do it then? -- - Antti
