Re: [Qemu-devel] User-space emulation on Mac OS X to run Mac OS X Intel applications

Hi all,

Looking at qemu, it seems as if it could be possible to allow it to
run Intel OS X apps on PowerPC OS X, much like a reverse Rosetta. The
x86 frameworks/libraries are included with Xcode, so possibly
everything else could run natively, just have the app itself emulated.

Is anybody willing to try getting this to work?


I used to work on it. I will resume the work in 6 months.

The remaining problems were mostly the apple only (that only dyld  
should call) syscalls like load_shared_file, which needs to be  
implemented properly.


Pierre.

Re: [Qemu-devel] Problems with Zeta LiveCD

[Christian Wiese]

Hi,

this behaviour is because of the way a BeOS/ZETA cd is constructed. For 
some more infos take a look at the bottom of this page:

http://forum.mlotz.ch/viewtopic.php?t=120

What you could do:
- Make a boot floppy out of track one of your demo-cd.
- Extract the second track as iso (be sure to take only the second track)
- In qEmu boot from your virtual floppy, press `space` to access the 
bootmenu and select your virtual hd.
This way I get a complete ZETA installed in qEmu. But don´t expect to 
much, as most hardware is currently not supported (the last time i tried)


Greetings,
Chris

Re: [Qemu-devel] Problems with Zeta LiveCD

[Ulf Magnusson]

I noticed the official distribution already has the two tracks split into zetaboot.img and zetacd.img, so that's less work me :)

I ran

$ qemu -cdrom zetaboot.img -hda zetacd.img -boot d

and selected the hd from the boot menu. That led to a kernel panic (PANIC: boot device not found"). 

I then tried running without any hd, and instead changed the disk to
zetacd.img from the console when the prompt for the CD came up. That
way I got to the magnifying glass stage of the ZETA boot screen, but
there it panics with "PANIC: no shell!". Any ideas?

Thanks for your reply,

Sorry, haven´t the files here till now.
But maybe you could try something like that:
qemu -floppy zetaboot.img -cdrom zetacd.img -boot a
If I get the live cd the next days I´ll try with it myself.

[Qemu-devel] Re: Julian's My story

[Juozas Bromley]

I am in good health and have always enjoyed sex.
I was losing my erection during intercourse and during oral sex with 
my girlfriend.
It was difficult to pinpoint the problem so I decided to order some 
Vjagrra online.

I ordered my Vjagrra which arrived in several days. I ordered 4x100mg 
pills and on the weekend decided to give it a go without saying 
anything to my girlfriend ;) 35 minutes before we went to bed I took 
half a pill, and WOW! what a difference. 

I had a rock hard erection for over an hour of non stop sex. Even 
after I had climaxed I was ready to go again in twenty minutes, which 
we did. this lasted for over two hours, and I was still hard in the 
shower after. 

It was like being a teenager over again. Amazing!

If you have a problem, try Vjagrra, it is great http://www.chosenam.com

[Qemu-devel] Problem running Sparc on OS X

[Bob Nestor]

Last month Jose Renau posted a patch titled " SPARC patch for OS X  
(big endian machines)". Without his patch there is no output to the  
screen when booting Sparc on OS X.  With his patch I get the console  
output from PROLL.  I was actually able to boot the first stage  
bootstrap of the Debian Sarge distribution.  Unfortunately the patch  
doesn't solve the problem of booting a Solaris installation CD, but I  
think this may be due to a disk block size problem.  (Sun and MacPPC  
assume a 2048 byte disk block size on the CD.)


Here's Jose's original message with his patch:


Without the following patch, I was unable to "start" the Linux boot  
process

on OS X (powerPC bigendian). I tried on ia64 (Linux) and works fine too.
