[Qemu-discuss] SunOS 4.1.4 on Qemu 2.10.0 on Mac OS X 10.12.6 on mid 2012 Intel MBP w/16GB RAM

[Will Senn]

Hi,

I heard on the TUHs mailing list that it was possible to emulate sparc 
on qemu and further that you could run SunOS. So, I did the following:


brew install qemu - which got qemu on my mac

rounded up the sunos 4.1.4 install media and the sparcstation 5 version 
2.15 boot prom


and then followed the directions (and a bunch of variations) at 
https://en.wikibooks.org/wiki/QEMU/SunOS_4.1.4


When I got to the post-install reboot, the VM booted up to the point 
where it was starting network services and then reported a bunch of, 
"rpc.lockd: Cannot contact status monitor!" and hung. I thought maybe it 
was environmental, but I got the same errors on Linux Mint 18 with qemu 
1.7, 2.0, and 2.14 as well as on FreeBSD with qemu 2.8.1, so I'm asking 
for help.


First question - is there a better/more up-to-date guide than what's on 
the wiki (I googled but didn't find anything better)?


Second question - any idea why the error is happening or how to make it 
stop (google returned a bunch of Sun notes saying stop and restart rpc, 
but this isn't really helpful as it happens during boot and it hangs 
without letting me make any changes)?


Third question - has anyone heard of this working on modern hardware and 
software configurations (the Wiki article is pretty old and the few 
videos I saw on youtube were Crunchbang - circa Ubuntu 8?


Any substantive help appreciated.

Thanks,

Will

There is no QEMU 2.14 -- 2.10 is the most recent release. I would start
by trying with 2.10. Given the description of the symptoms it's quite
likely it won't help, but it's an easy thing to try.

thanks

I'm not sure where I got the 2.14 from, it's actually 2.5.0:

Maybe there is something wrong with the disk image you downloaded or something 
else went wrong - so I'm going to put the BIOS and disk file in an archive and 
send you an email with the download location.

Minix 1.1 with QEMU

[Will Senn]

Long time user, first time poster :)

So, I'd like to be able to run Minix 1.1 on my Macbook Pro mid-2012 
w/16gb RAM (MacOS 10.14.6 Mojave). Qemu will run pretty ancient OS'es 
such as DOS 2.0, which I use all of the time. However, I'm having some 
difficulty getting Minix to run. I am able to boot the first floppy, but 
when I change to the second floppy, the system freezes and I can't tell 
what is going on. Here's what I did to get this far:


brew install qemu

qemu-system-i386 --version
QEMU emulator version 5.1.0

mkdir ~/workspaces/retro-workspace/minix-1.1
cd ~/workspaces/retro-workspace/minix-1.1
aria2c 
http://download.minix3.org/previous-versions/bzipped/Intel-1.1.tar.bz2

tar xvjf Intel-1.1.tar.bz2
cp Intel-1.1/floppy_disk1 ./Disk01.img
cp Intel-1.1/floppy_disk2 ./Disk02.img
cp Intel-1.1/floppy_disk3 ./Disk03.img
cp Intel-1.1/floppy_disk4 ./Disk04.img


qemu-system-i386 -drive 
file=Disk01.img,format=raw,if=floppy,media=disk,readonly=off,index=0,snapshot=on 
\

  -boot a \
  -no-fd-bootchk \
  -monitor telnet::,server,nowait -serial mon:stdio

Qemu boots to the Minix 1.1 Boot screen and says to swap to floppy 2, so 
in the monitor:

change floppy0 Disk02.img raw

I press l (el) and it scans the disk, lists the files on the disk and 
reports no errors, but when I press =, it does a carriage return and 
just sits there. I'm pretty sure this is the Minix going bye bye and not 
necessarily QEMU, but I'm wondering if there is a way to see what QEMU 
thinks it is doing or if it is what's hung? Usually, at this point, 
Minix reads the disk contents into a Ramdisk and boots Minix.


Food for thought... Minix expects to run on an IBM PC (5150), IBM PC XT 
(5160), or compatible, and therefore the I/O is written for whatever 
floppy controller was extant at that time (I'm guessing here), so if 
that's different than modern day floppies, I suppose this could cause 
the problem I'm experiencing here. Is there a way to see the floppy 
controller activity in QEMU? Similarly, I gather it expects a CGA 
compatible monitor (EGA/VGA, etc should be fine).


I appreciate your help on this.

Minix 1.1 works 'ok' in 86Box and other IBM PC emulations, so I know the 
floppies are fine.


Thanks!

Will

Can you try adding '-machine isapc', which is closer to the 5150?

Phillipe,

My new incantation is:

qemu-system-i386 -machine isapc -drive 
file=Disk01.img,format=raw,if=floppy,media=disk,readonly=off,index=0,snapshot=on 
-boot a   -no-fd-bootchk   -monitor telnet::,server,nowait -serial

with the same outcome :(. Thanks for the suggestion, I'll keep it in

pause-break mapping for macbook pro laptop keyboard

[Will Senn]

All,

Is there a way to map an existing key on my macbook to the dos/windows 
key pause-break for QEMU? I'd like to be able to press the equivalent of 
CTRL-BREAK in DOS while running in qemu and this doesn't seem 
straightforward. I can CTRL-C all day long and where that works, it's 
fine, but it isn't the same functionality as CTRL-BREAK. It seems 
logical that I should be able to tell the macbook to send a specific key 
to the qemu window, but I can't seem to locate any relevant help.


Is this possible (I've done it with dos-box-x, so I know it's possible, 
tricky to be sure)?


Thanks,

Will

Emulate pc speaker in QEMU on MacBook Pro?

I see this, in the manual:

The PC speaker audio device can be configured using the pcspk-audiodev 
machine property, i.e.


qemu_system-x86_64 some.img-audiodev    
,id=-machine    
pcspk-audiodev=


I'm on a macbook pro, what  do I need to specify, and what is 
 supposed to be for id and pcspk-audiodev in order to get the pc 
speaker sounds of my dos 2.10 instance to be audible on my mac? I could 
find ANY explanation of what these values might be...

 is anything (it's an identifier in case you want to have

on a Mac (sdl might be available too, I'm not sure, see the list under 
the -audiodev option).  So something like this:

Hi Zoltan,

Thanks for the hint. I tried it and I didn't get any error, but I also 
don't get any speaker sounds. How do I troubleshoot. I've got the 
monitor open and I don't see any errors. Is coreaudio something native 
to my mac, or something I need to install/configure and is audio0 the 
usual default device? Sorry if this sounds newbieish.


Thanks,

Remap a key

[Will Senn]

I've been digging into the lack of a proper break key on laptops (my 
MacBook for example) and I was wondering if it would be possible to 
remap one of the existing keys on the laptop to the CTRL-BREAK key, 
which sends the scancode E0 46? I'd be fine with having CTRL-ALT-] map 
to it or pretty much anything not typically typed in DOS. But doing 
assembly programming in DOS without a break key is frustrating to no 
end. Pointers to qemu keymapping documentation would be helpful or any 
sort of 'here's a keymapping example' tip.


Thanks,

Will

1. Use the appropriate hot-key to switch to the qemu monitor screen

This can of cause be automated by having software on the guest

Another available method is to use the VNC console and a VNC client

Hi Jakob,

I get:
sendkey ctrl-break
invalid parameter: break

Is there a list of valid parameters?




It's not in the official documentation but, to get a list of keys, 
type sendkey [tab].


Awesome, thanks. Maybe ctrl-pause...

Re: Emulate pc speaker in QEMU on MacBook Pro?

Hi Will,


 is anything (it's an identifier in case you want to have multiple 
audiodevs).  For backend you probably want to use `coreaudio` on a Mac (sdl might be 
available too, I'm not sure, see the list under the -audiodev option).  So something 
like this:

     -audiodev coreaudio,id=audio0 -machine pcspk-audiodev=audio0

I expected you have working audio playback with these qemu command line 
arguments. To exclude a problem with your guest please run 'Day 1 - F-Bird' 
from the QEMU Advent Calendar 2018. I know this program uses the pc speaker.
Well, I thought you were pulling my leg, with the greek 'Day 1 - F-Bird' 
stuff, but a google search led the way to the Advent Calendar, and lo 
and behold, It works!


qemu-system-x86_64 -audiodev coreaudio,id=audio0 -machine 
pcspk-audiodev=audio0 -fda fbird.com



On the dos instance, no joy. Here's my runfile, does it look sane?

#!/bin/bash
qemu-system-i386 -machine isapc \
  -drive 
file=C.img,format=raw,if=ide,media=disk,readonly=off,index=0,cache=unsafe \

  -boot c \
  -audiodev coreaudio,id=audio0 -machine pcspk-audiodev=audio0 \
  -drive format=raw,file=empty1.img,index=0,if=floppy \
  -drive format=raw,file=empty2.img,index=1,if=floppy \
  -monitor telnet::,server,nowait -serial mon:stdio &
sleep 1
telnet localhost 

No beeping here. Next thing I'm going to try is running fbird from dos.

It's progress!


Thanks,
Zoltan

Hi Zoltan,

Thanks for the hint. I tried it and I didn't get any error, but I also don't 
get any speaker sounds. How do I troubleshoot. I've got the monitor open and I 
don't see any errors. Is coreaudio something native to my mac, or something I 
need to install/configure and is audio0 the usual default device? Sorry if this 
sounds newbieish.

Thanks,

Will

I spoke to soon. As soon as I quit the monitor, an error was displayed:

coreaudio: Could not lock voice for audioDeviceIOProc
Reason: Invalid argument

Did this error message appear after you typed quit in the monitor? Then it's a 
bug in the qemu coreaudio shutdown routine and you can ignore this message.

Yes, it came after. No worries, I'm going to fiddle with this.



With best regards,
Volker

Volker and Zoltan,

To wrap this up, fbird.com works in dos and I have sound. So, consider 
this issue resolved! Thanks for your help and patience. Now, I just 
gotta figure out what's wrong with my beeping (not bleeping) assembly 
code :).

Re: OT - 24-pin dot matrix printer emulator (nlq etc.)

[Will Senn]

Hi Supratim,

This may not  be exactly what you're looking for, but it's related. I 
use 86box to emulate IBM PC (but it'll emulate anything up to Pentium 
III class machine (if I remember correctly). One of the emulated LPT/PRN 
devices is the Epson dot-matrix printer. It works really well (it 
generates pngs, which I put into pdf and print on my laserjet). I have 
no idea whether they borrowed the device from another emulation or what. 
I only use it from DOS, but 86box will probably run Win 98 without too 
much trouble.


Later,

Will

Hi

Possibly off-topic, but does anyone know of or use some sort of a 
Epson or whatever 24-pin dot matrix printer simulator that would, for 
example, create a virtual parallel port for other simlated instances 
of operating systems (Windows 98SE for example) to print to? Ideally 
it would understand escape sequences for NLQ fonts etc.


Thanks
