<br>
<br><font size=3 face="Calibri">I have two physical systems, a VAX 6220
and a VAX 4000-300. The latter system is set up to do a network bootstrap
off the 6220 using an EZA0 network device.</font>
<br>
<br><font size=3 face="Calibri">First, using vddriver and backup/image,
I generated and retrieved disk images of the RA92 drives from the 6220.
With these disk images, and specifying MicroVAX 3900 on the SimH
simulator, I am able to boot up an emulated version of the 6220 on my laptop.
So far so good.</font>
<br>
<br><font size=3 face="Calibri">My first goal is to get the physical VAX
4000-300 to do its network bootstrap off the emulated 6220 rather than
the physical 6220. By the way, I am running SimH 4.0 on Windows 8,
it seems to work OK.</font>
<br>
<br><font size=3 face="Calibri">The first problem I ran into was that the
simulator presents a different network adapter to the emulated 6220 than
it is accustomed to seeing. It typically sees a "BNA-0"
interface, but the simulator uses "QNA-0", as derived from the
XQA0 device. So, I found out that I needed to run netconfig.com.
When I ran that script, it brought the circuit online.</font>
<br>
<br><font size=3 face="Calibri">But when I tried to do network boot of
the physical VAX 4000-300 off the emulated 6220, it kept saying 'retrying
network bootstrap'. So evidently that was not sufficient. Then
I came to discover that the 6220 uses DECserver, and there is a dsvconfig.com
script. Once again, because the simulator presented a different network
device than the 6220 was accustomed to seeing, the configuration had to
be updated. So okay, I ran the dsvconfig.com script, and made it
aware of the fact that it is now a "QNA-0" device rather than
a "BNA-0" device.</font>
<br>
<br><font size=3 face="Calibri">So after running both netconfig.com and
dsvconfig.com on the emulated 6220, the physical 4000-300 no longer says
"retrying network bootstrap". Instead it now appears to
be able to communicate, but it says "unable to locate boot file":</font>

<br><font size=3 face="Calibri">>>></font>
<br>
<br><font size=3 face="Calibri">Using Wireshark, I captured some of the
packets to try to glean some more details, and I see messages like "VAXcluster-F-NOSUCHDEV,
nonexistent drive" and "VAXcluster-F-READERR, I/O error reading
boot file".</font>
<br>
<br><font size=3 face="Calibri">I am really stumped on this one because
basically the disk images should be one-to-one copies of what is on the
physical VAX 6220, so other than having to tell it that it has a different
network adapter (QNA-0 rather than BNA-0), why shouldn't it just work?
Does SimH not support MOP or DECserver? I did check, and the
sysboot.exe file is present in dua0:[sys14.syscommon.sysexe], and sys14
is the directory for the VAX 4000-300 to use for its network boot. So
I believe the boot file is available.</font>
<br>
<br><font size=3 face="Calibri">By the way, the VAX 6220 is running VMS
5.5-2H. And I have set VAXCLUSTER to 2.</font>
<br>
<br><font size=3 face="Calibri">Oh and one more thing, when the 4000-300
fails to boot, on the simulator side of things I see the following:</font>

</font>
<br><font size=3 face="Calibri">So it almost looks like it has done a successful
load of the system software to the 4000-300, but then the port closes presumably
due to not being able to locate the boot file.</font>
<br>
<br><font size=3 face="Calibri">My thoughts are that maybe:</font>
<br><font size=3 face="Calibri">1) there is some other config script that
needs to be run when using disk images from one VAX system (physical 6220)
to another (simulated MicroVAX 3900)</font>
<br><font size=3 face="Calibri">2) SimH on Windows 8 does not really support
MOP or DECserver stuff?</font>
<br><font size=3 face="Calibri">3) there is some permissions issue with
the boot file (sysboot.exe?), but since it is off a disk image (which should
be a one-to-one exact copy), how so?</font>
<br>
<br><font size=3 face="Calibri">Any ideas? Thanks in advance.</font><tt><font size=2>_______________________________________________<br>
