If so, it looks like i'll throttle the execution rate as well as running the VMs on 10BASE-T ports. ;) Idling for any simulator requires that the host system's clock tick be <= the size of the simulated system's clock tick. VAX systems have a clock tick of 10ms. Idling for simulated VAX systems works best if the host clock tick is 1ms. Windows systems have a user mode programmatically settable clock tick size (a facility useful for some media playback capabilities). On Windows systems simh will set the host's clock tick to 1ms while a simulator is running. We haven't seen programmatically settable host clock tick sizes on other platforms. In general, other platforms have a tick size which can be changed in some system specific way (which might require building a kernel with a desired tick size) or not changeable at all. This issue comes up often enough that adding how to make these system specific adjustments would be a useful addition to the simh FAQ. Any feedback on this subject will be welcome. Recent simh code will display what it has determined to be the host's clock size if simh believes the host's clock tick is too small to support idling when you attempt to enable idling. Recent simh code can always display host system's tick size with the 'EXAMINE TIMER OS_SLEEP_MIN_MS' command. The latest simh code is available from https://github.com/simh/simh/archive/master.zip.

I haven't heard from anyone who's had issues getting idling to work on Windows. If you know of such a case, I would be interested to explore what may be happening in this case. Thanks. - Mark Pizzolato

RSX-11M v4.1 SYSGEN - OK, I give up - what am I doing wrong?

Interestingly, 11M v3.2 BL26 works fine, even after the SYSGEN, but I don't have DECnet for that. 11M v4.0 BL32 and 11M v4.1 BL35 both fail after SYSGEN in exactly the same way. 11M v4.2 BL56 works, but won't fit on an RL02 anymore (or at least I can't figure out how to fit it on such). I had to build it on an RD drive instead - that's of no consequence on simh (where hardware is free!), but isn't going to work on the real machine. I think any version of 11M should be able to fit on an RL02. But there might be some special considerations that are needed. I seem to remember building such a thing, about 20 years ago... Johnny

Try creating a new RSX11M.SYS, which is a bit smaller, and then rerun the VMR command, Nope - no change, but thanks for the idea. I didn't think that was it - notice that it actually gets far enough to print the MCR ">" before it dies - boo [1,54]rsx11m RSX11M V4.1 BL35 SYSTEM CRASH AT LOCATION 025614 REGISTERS R0=025232 R1=056270 R2=010464 R3=034766 R4=033262 R5=000000 SP=000710 PS=030010 - so I don't think it's having a problem loading the memory image. It's something after that which dies ... Bob

I'm letting it autoconfigure and I'm taking pretty much the default answer for everything. The build seems to go without error and yet the resulting system crashes as soon as it boots. I give up - what am I doing wrong? Somebody give me a clue, please! The simh log is attached. When RSX is building the system, it at one point creates the new system image to run, called [1,54]RSX11M.SYS. The relevant line is PIP RSX11M.SYS/CO/NV/BL:498.=RSX11M.TSK Now, your machine only have 128kW. That is 256 kByte. Of this, 8 kByte goes away because of the I/O page. Leaving 248 kByte. This is 496 disk blocks. It *might* be that your disk file is too big, making the system assume that it can place stuff in memory that don't exist. RSX11M.SYS is pretty close to just a memory dump. Try creating a new RSX11M.SYS, which is a bit smaller, and then rerun the VMR command, and try booting that file instead and see if that helps? Johnny
