<p>Miltonwulei: simh 4.3BSD reno dhq dh</p> <hr /> <div>Because the dz11 driver in 4.3BSD RENO can not work on simh emulator. So I found a walk arround method.That is to use dh11 replace the dz11. I test it and it does function with a bit of flaw.<br /> <br /> I use the following code to replace the original dz configration.<br /> set dz disable<br /> set vh enable<br /> set vh0 normal<br /> set vh0 modem<br /> set vh0 hangup<br /> att vh 2311<br /> <br /> After this, when the vax emulator run up, you can see some messeges on the process of booting like this<br /> :<br /> dhu0 at uba0 csr 160440 vec 300, ipl 14<br /> qe0 at uba0 csr 174440 vec 764, ipl 15<br /> qe0: delqa, hardware address 08:00:2b:aa:bb:cc<br /> <br /> this mean that the hardware is recognized by virtual machine.<br /> <br /> next step, login as root, to make dh11 device node in /dev .<br /> <br /> sh /dev/MAKEDEV dhu0<br /> <br /> this command will make ttyS0 - ttyS15 device node.<br /> <br /> now, you need to modify /etc/ttys to add those termial driver to autoload when system startup next time. the parameters is same with tty01-tty07 in the original ttys file.<br /> <br /> At last you could reboot and telnet localhost on port 2311.<br /> <br /> you will see the prompt, but there will emerge some flaw (some messed characters). but you can neglect this, and continue input your username and password. then you will get a shell.<br /> <br /> Now, I don't know the reason of those messed characters. Any one can continue to explore.</div>
