Hi all It seems it is Centos6 (specifically Centos 6.9, kernel 2.6.32-696) since I also tried on my Centos 7 -- not as recent as yours Mark (I don't like RHEL7/Centos7 so tend not to use it unless I need something specific).
Just like you I re-used my simh-master.zip (recent), built SimH (4.0.0-current) and ran pdp11 (no DEBUG). I copied the RL01 image I had already that I knew worked from my Win 10 storage onto Centos7 "local storage". I then did a cmp on the two for confirmation they were identical. Then created 11/70, 1MB RAM, IDLE enabled. Attached the new disk from local Centos7 storage and noted it was immediately correctly recognised (thanks for the tip Mark), booted and et voila! So there is something screwy with my Centos6 or the kernel. I will re-update Centos6 later and re-try, just in case.

You found your way there reasonably well. Building with DEBUG=1 is only necessary if you're planning on running the simulator under a debugger and plan to set breakpoints, etc directly in the simulator code. The simh provided debug output is always there without regard to having built things with DEBUG=1. Meanwhile, you've isolated things well to what seems to be where the Disk image file is located. To help yourself you should use host system tools to assure that the files are indeed EXACTLY the same. I pulled down a CentOS 7 ISO image and installed that in a newly created VirtualBox VM on my Windows 10 Laptop. I pulled the latest code from github.com/simh/simh master branch and built it and tested. This is what happened to me: [mark@localhost simh]$ make pdp11 *** Installing git hooks in local repository *** lib paths are: /lib64/ /usr/lib64/dyninst/ /usr/lib64/iscsi/ /usr/lib64/mysql/ include paths are: /usr/include using libm: /lib64/libm.so using librt: /lib64/librt.so using libpthread: /lib64/libpthread.so /usr/include/pthread.h using regex: /usr/include/regex.h using libdl: /lib64/libdl.so /usr/include/dlfcn.h using mman: /usr/include/sys/mman.h *** Info *** *** Info *** The simulator you are building could provide more *** Info *** functionality if video support were available on your system. *** Info *** Install the development components of libSDL packaged by your *** Info *** operating system distribution and rebuild your simulator to *** Info *** enable this extra functionality. *** Info *** using libpcap: /usr/include/pcap.h *** Info *** *** Info *** pdp11 Simulator are being built with *** Info *** minimal libpcap networking support *** Info *** *** Info *** *** Info *** Simulators on your Linux platform can also be built with *** Info *** extended LAN Ethernet networking support by using VDE Ethernet. *** Info *** *** Info *** To build simulator(s) with extended networking support you *** Info *** should read 0readme_ethernet.txt and follow the instructions *** Info *** regarding the needed libvdeplug components for your Linux *** Info *** platform *** Info *** *** *** pdp11 Simulator being built with: *** - compiler optimizations and no debugging support.

What is the size and md5sum of the file you are attaching to the RL0 device? Notice in my test the directory I'm working in the one for my user account on the local CentOS file system and is not a shared drive. The same results are observed if I use a file on a shared drive. If the md5sum of the disk image file is the same as mine, then I'll go and find a CentOS 6 image and dig further. If the md5sum of the disk image file differs, then first pull down and unzip a new disk image: $ wget http://www.mirrorservice.org/sites/www.bitsavers.org/bits/DEC/pdp11/discimages/rl01/rsx11m_3.2/RSX-11M_V3.2_RSX11MBL26_3.2.DSK.gz $ gzip -d RSX-11M_V3.2_RSX11MBL26_3.2.DSK.gz $ md5sum RSX-11M_V3.2_RSX11MBL26_3.2.DSK If this file doesn't have the same value as I do, then clearly the problem has nothing to do with simh. Once you've got matching input files, try with the minimal 2 SCP commands I used: sim> attach RL0 RSX-11M_V3.2_RSX11MBL26_3.2.DSK sim> B RL0 As you noticed, the output produced by the attach command will predict whether the boot will succeed. = Mark _______________________________________________ Simh mailing list Simh@trailing-edge.com http://mailman.trailing-edge.com/mailman/listinfo/simh
