[in short, mangled] I'll try to do better next time. In any event, I'll have to repost it anyway. I have found and repaired several major bugs. At the moment when the system boots, the message: "login: " appears on the terminal, and you can actually log in and most things work. I am still tracing down problems with CTRL-S and a few things. I'll report back as soon as I am done. One question, perhaps somebody can help me. I sort of have the feeling that RS232 port 1 uses vector 12 and port 2 uses vector 11. Is this correct? I have scoured the IBM XT Reference Manual from cover to cover, and--silence. If I were designing a PC, I'd do it the other way, but IBM didn't ask me. There is a minor problem with conflicting interrupt vectors (Ethernet vs. RS232), but I'll try to make that as modular as I can (e.g., if you don't compile with the Ethernet flag, you get 2 RS232 ports; if you have Ethernet, you get one). You can always change things around yourself fairly easily by modifying the calls in kernel/main that set the vectors. Andy Tanenbaum -- Andy Tanenbaum (ast@cs.vu.nl)
