Request to help for Sparc arch - Solaris vm creation.

Hi Openbios team, First of all I would like to thank you for the contribution to opensource community which is helping lot of developers like me to progress professionally. It would be great if you can help me with the problem I am facing with using qemu with openbios . I am trying to create a solaris environment with sparc architecture on an ubuntu 14.04 linux OS with help of qemu-system-sparc . When I am trying to load a solaris image using this qemu-system-sparc64 i am getting the following error message . When I tried debugging it I found that the openbios-sparc is not installed in ubuntu machine I am working with . This qemu-system-sparc64 uses a softlink which points to the directory /usr/share/qemu/openbios-sparc64 which is not found in the machine . I am stuck here , I am not sure what should be the contents of the above directory so that this sparc emulation works good . I tried to install the openbios from your official website but failed in using it along with qemu . Can you please help me to get out of this situation or suggest me some way to create a 64 bit sparc solaris environment on linux os . Thanks in advance :) Warm Regards, Tej =====-----=====-----===== Notice: The information contained in this e-mail message and/or attachments to it may contain confidential or privileged information.

Once the package is installed you should find that QEMU can locate the binary automatically. As regards running Solaris under Linux using qemu-system-sparc64 sadly this is still a work in progress. Since the work is currently unsponsored then myself and a few others are quite restricted in the time we can spend on this so progress isn't as fast as we would like. On the plus side, qemu-system-sparc64 is getting much more reliable with newer QEMU/OpenBIOS releases and is now capable of booting NetBSD/OpenBSD and (nearly) FreeBSD. So all I can say about Solaris for the moment is watch this space :) ATB, Mark.

openbios has some warnings (that are errors with -Werror) on gcc6.

Re: [OpenBIOS] [PATCH] bootinfo_load.c: Translate \r to \n for Mac OS 9 compatibility

I forgot to mention that this patch eliminates the error message printed by Fedora when using the older forth-based CR and LF filtering patch.

Why some Linux distributions start booting to black screens
by Programmingkid March 11, 2016

March 11, 2016

Some Linux distributions like Fedora start booting to an all black screen. I found out the reason why is because there appears to be something wrong with the screen node's color! word. If you type these commands in OpenBIOS: dev screen see color! You will see that color! is empty. This would definitely prevent the color of text from being changed.

[PATCH] bootinfo_load.c: Translate \r to \n for Mac OS 9 compatibility
by Programmingkid March 8, 2016

March 8, 2016

Mac OS 9's bootscript uses '\r' a lot. These interfere with how OpenBIOS functions. So the solution is to translate them to '\n' characters. This will allow Mac OS 9 to boot. Signed-off-by: John Arbuckle <programmingkidx(a)gmail.com> These are the operating systems I used to test my patch. - Mac OS 10.4.0 - Mac OS 9.2 - Fedora Linux 17 - Debian Linux 5 No regressions have been detected.

Google Summer of Code 2016
by Programmingkid March 1, 2016

March 1, 2016

Hi Mark, I was wondering if you were willing to be a mentor again for another student for this year's Google Summer of Code. Last year Cormac O'Brien made a lot of progress that put us into view of making Mac OS 9 work in QEMU. This year we could bring on someone else who could eliminate all these extension problems. Your work with Cormac last year was very impressive. Would you be interested in mentoring this year? I am thing about making the title to this years Google Summer of Code entry as "Make Mac OS 8.0 and higher work in QEMU". Nothing set in stone yet.
