Qemu OS/2 TCP/IP networking

Posted on by

Well this should have been ‘easy’ but let me assure you it was not.  However this may save someone LOTS of effort if they ever want to get TCP/IP running in a fossil like OS/2 2.0.

First of all OS/2 2.0 will not install in new versions of Qemu.  I had to go all the way back to Qemu 0.9.0!  Although there is a tonne of floppy images to shuffle, OS/2 2.0 will install somewhat straightforwardly.  Once OS/2 is installed, You will almost surely want the xr06100 service pack.  I found I was unable to run MS-DOS or WinOS/2 sessions at all without either crashing the system, or trapping the entire OS.  But after loading the service pack it works as expected.

Now Qemu supports all kinds of network cards, from the NE2000 ISA, a PCI version of the NE2000, the rtl8139, an AMD PcNET adapter, and a bunch of Intel adapters.  And the annoying thing is that the OS/2 driver I have for the AMD PcNET adapter does not work at all.  It can’t find the card no matter how much I tried.  Which is funny when Netware 3.12 of all things can see it…

I tried all kinds of NE2000 drivers set for 0x300 irq 3 or irq 9 (I changed hw/pc.c to reflect what it was set to) to either not loading, or it’d load and transmit packets, but NEVER receive any packets.

The rtl8039 (ne2k_pci) and rtl8139 would also either not find the card, crash on binding, or send packets and again receive nothing.  To say it was very annoying was an understatement.

So I almost gave up, I found some update for the TCP/IP, u64092 went through the needed fun with loaddskf, and finally got working diskettes, and … It still didn’t work.

So in a fit of rage, I removed the 0x300/9 ne2000 in the config, so the next one, the 0x320, IRQ 10 one is in order, and….. It worked!  It even works with the Microsoft NE2000 driver!

So I go ahead and modify Qemu 0.14.1 to force the ne2000 to 0x320/IRQ 10, and it works great on the latest version!  It’s a shame it doesn’t install… But hopefully you only need to do that once!

So there we go, saved by the NE2000 again.

For anyone crazy enough to reproduce this, here is my config.sys & protocol.ini … I’ve also installed EMX, but I don’t think that really matters…

 

Looks like more outages ahead..

“We’re moving most of our servers from SVTIX[1] to Market Post Tower[2] this
weekend. we’ve got layer 2 between the two locations already, so we’ll
be bringing down servers in batches of five and moving them five at a shot.
each user should experience something like two hours of downtime, if all
goes well.”

Well at least luke is transparent on the whole thing so it looks like there will be more bumps ahead. But I do have a full backup so worst case I can bring this online elsewhere if this goes down.

If anything the blogger outage made me finally break down and get that squared away.

Qemu 0.14.1 released!

I just found out that a new version of Qemu has hit the street!  From the changelog:

  • Version 0.14.1 (commit)
  • virtio-blk: fail unaligned requests (commit)
  • qed: Fix consistency check on 32-bit hosts (commit)
  • exit if -drive specified is invalid instead of ignoring the “wrong” -drive (commit)
  • vhost: fix dirty page handling (commit)
  • Do not delete BlockDriverState when deleting the drive (commit)
  • vnc: tight: Fix crash after 2GB of output (commit)
  • lan9118: Ignore write to MAC_VLAN1 register (commit)
  • Don’t allow multiwrites against a block device without underlying medium (commit)
  • lsi53c895a: add support for ABORT messages (commit)
  • virtio-pci: fix bus master work around on load (commit)
  • fix applesmc REV key (commit)
  • rbd: don’t link with -lcrypto (commit)

  • vnc: Fix fatal crash with vnc reverse mode (commit)
  • qemu-char: Check for missing backend name (commit)

I’ve also included my patches to enable ctrl+alt+d for a quick control alt delete, ctrl+alt+r for reset, and the ISA Cirrus adapter.

As always, I’ll have win32 builds up in the usual spot.  i386/x86_64 and everything else.  I’ve tested these on Windows 7 x86_64, and they should work on XP & Vista i386 as well.

Also I’ve switched this to 7zip to save space.

 

So this VM walks into a bar…

OK, I saw this shamelessly come through on google…
And I must admit, I really don’t have one.  But I did find a funny picture in an ancient OS/2 SDK, from Microsoft…

Heh.  Then again zippy the pinhead was quite popular in the 80s.
Yow!  Did something bad happen or am I in a drive-in movie??

Which sure does remind me of stuff like this…

Whole lot of virtualization going on!

Emulators in emulators, in emulators in emulators… (XP in Virtual PC, Windows 95 in Qemu, MacOS in Mini vMac, MS-DOS in SoftPC)..  It reminds me of  Inception…

Arduino: Core memory for your pc

A picture of Arduino core memory

Arduino Core memory shield

While the site, corememoryshield.com is more so geared to making your own, they do provide the information needed to build your own core memory…

One has to wonder if in the future, some kids will struggle to get a hard disk working, or perhaps attach DRAM to a pc…

Then again I am pretty sure that SIMH, emulates machines that most certainly used core & drum memory…

I’ve gotten it listed, and gussied up a web page!

But to be honest it seems that version 2 is pretty scarce.. I’ll have to see about what it takes to add more stuff, or maybe an upgrade… I just hope it doesn’t entail replacing the whole OS!

Then again NetBSD 1.2 is possibly old enough….

I just saw on the PCC mailing list that it just built NetBSD

Some speedup with AberMUD & 4.3 UWISC.

So I found out why it’s now taking FOREVER to logon to the mud..

It turns out that there were nearly 4000 entries in the hosts file. Wow that’s a tad crazy eh? I guess this tape of BSD shows what the internet was like before DNS. I also bumped the CPU up to 4%.. it’s far more snappier.

Now to see if I can get added to abermud.info

Also as mentioned in the prior post, the AberMUD tape doesn’t just magically install, you have to run the install.sh & install2.sh which will recompile everything and set some paths, then install the DB in /usr/tmp as -iy7AM .. I guess it’s harder to forcefully delete it. Anyways logon as ‘debugger’ set yourself up a password, then run ‘reset’ to finalize the placement of everything….

And looking at the mud_syslog you can see fun stuff like this:

GAME ENTRY: Neozeed[root]
GAME ENTRY: Neozeed[root]
GAME ENTRY: Gatto[root]
GAME ENTRY: Geophoto[root]
Neozeed slain by The Yeti
GAME ENTRY: Neozeed[root]
GAME ENTRY: Erazmus[root]
GAME ENTRY: Neozeed[root]
GAME ENTRY: Jose[root]
GAME ENTRY: Neozeed[root]
GAME ENTRY: Nek[root]
Nek slain by The Yeti
GAME ENTRY: Lumpy[root]

So I don’t feel that bad being slain by the Yeti. Maybe one of us can kill the thing.

** UPDATE **

>
The Yeti attacks you
You hit The Yeti with the scimitar
Your last blow did the trick

The Yeti has just died
