The only problem is that I still haven't managed (in 3 years) to find time to spin it into a release. :-( There is some hope, though, that I'll find a bit of time (enough to spin out the 4.3-QJ0b release) this winter.

It was Q0A. Has there been any later development of it, of interest? Thanks Bob

The plain original 4.3 doesn't run on MicroVAXen, so if you had 4.3 on yours, it must have been *some* enhanced version. MS

Re: non-broken 4.3BSD set?

by Robertdkeys＠aol.com

The src tarball in the archives is only 35k or something like that, so it is mostly gone. At one time, I thought it was more there. Since I was only needing the dwb section out of the sources, to power up a dwb suite on an ancient ultrix box, I just used the quasijarus 0a source tarball (that is supposed to be Tahoe) for the bits I needed. It worked. But, for the record, it might be nice to have a complete, unbroken set, if it still exists, and the bits can be rounded up. Out of curiosity, anyone still running a 4.3BSD box? I had a couple microVAXes up with it until my ESDI drives went bellyup a few days back. (Ice storms and power glitches ate the drives.) I have maybe 30mb of ports of this and that (gzip, gmake, psroff, TeX, and other things) that I would donate to the archives if there was any interest. MicroVAXen are a cheap way of playing old BSD....(:+}}... Thanks Bob

raise of interrupt level necessary

by Wolfgang Helbig

Hi, While studying the V6 kernel, I search for some rules as when to raise the interrupt priority level (IPL). I came up with something like this: A kernel process needs to raise the IPL if a change of data must be atomic and might be accessed (not necessarily changed) by an IRS. In light of this rule, some raising of interrupts seem unnecessary: - In m40.s changes of the user space segmentation registers are bracketed by raising and lowering the IPL, although these registers are never accessed by an ISR. - Likewise, in m40.s, just before the trap routine checks the runrun flag and restores r0, r1 and the user stackpointer, it raises the IPL. I can't see what possibly should go wrong, if being interrupted while restoring the values. I'd appreciate any help from someone with more experience in kernel programming. Greetings, Wolfgang Helbig

RE: [pups] Boot_Images and the networking activated version of Simh

by Fred N. van Kempen

People, DO note that the Ethernet operations of SimH heavily depend on the proper workings AND configuration of a Packet Filter driver for your platform, so, something like BPF, EFILT, NetFLT or WinPCAP (for Win32). Try running a test app for that stuff BEFORE trying to run SimH/ENET stuff.. if the test app works OK, you can start figuring out why SimH/ENET doesn't work on your system. I have *three* network cards the drivers of which DO NOT support promisc mode. Which obviously results in WinPCAP (they're PCI cards under Win2K) not functioning properly, and, thus, same for SimH/ENET. --fred > -----Original Message----- > From: Andru Luvisi [mailto:luvisi@andru.sonoma.edu] > Sent: Friday, November 29, 2002 8:02 AM > To: gregg(a)levine.name > Cc: pups(a)minnie.tuhs.org > Subject: Re: [pups] Boot_Images and the networking activated > version of > Simh > > > On Thu, 28 Nov 2002, Gregg C Levine wrote: > > Hello from Gregg C Levine > > Just out of curiosity, can the boot images stored in the > folders that > > are under that name, actually support this new version of > Simh?

Re: [pups] 2.11BSD networking on simh

by Steven M. Schultz

Hi - > From: Andru Luvisi <luvisi(a)andru.sonoma.edu> > I have gotten 2.11 installed on simh, I have it recognizing the simulated > ethernet card, and everything appears correct except the packets just > aren't getting in and out. The simh documentation says that the DELQA > card is better than the DEQNA, but I was unable to get the DELQA (qt) > driver to recognize the card. When I compiled the kernel to use the DEQNA There are TWO variants of the DELQA as I recall. One was referred to as the "turbo" verion (I think it was called the DELQA-YM) and the if_qt driver was developed and tested specifically for, and only for, that variant. The normal DELQA and DEQNA should use the if_qe driver. > I have configured 2.11BSD with: > A valid IP address on the network the host is on. > The same netmask, broadcast, and gateway as the host. > I am running the emulator as root. > > The docs say you won't be able to talk between the host and the emulated Hmmm, that seems strange. Using P11 I talk between the host (the machine running the emulator program) and the "PDP11" all the time. Ah, it has to do with ARP handling I suspect. I know that with P11 it's IP only and thus ARP packets do not traverse the emulated ethernet card. If that is the case with simh as well then on the PDP11 side you might have to do what I did and install arp entries for everything on the local lan with which the PDP11 is going to communicate. That way the 11 already knows the 'mac' address and does not need ARP (which doesn't work thru the emulated ethernet) at all. > machine, so my test for each configuration has been pinging the gateway, > which I know responds to pings since I can ping it from the host. Ah, but on the host did you publish an ARP entry so that the host will arp for the PDP11? I think that is required. I would tinker around with installing published/proxy arp entries and seeing what happens. Cheers, Steven Schultz sms(a)2bsd.com
