I eventually got it to boot. I was using the last updated debian binaries package from repository but this one seems not to be update.

When compiling qemu-1.3.0-rc0.tar.bz2 from qemu.org (which says 12.9 to info version though), boot from disk2:d is fine.
I got a disk image from a real machine to boot in no-graphic mode.

Question: does anyone has experience with frame buffer and graphics from SS5 emulated? I still got a "no frame buffer" in the boot sequence when I remove the option -nographic.

Thanks for your help & time.
Have a good day all,
Jean Michel

I am new to Qemu..

I would like to use Qemu in the following context:
Emulate a Sparc5 running SunOS 4.1.3 on a i386 machine (installed in Debian so far) and use from the emulated Sparc an Ethernet terminal server hosted by the Debian host machine.

I have been using SunOS and Solaris for years, (starting career with "true" Sparc2...) but I cannot go further than the open boot prompt this time.

I follow a few tutorials from the net like:

All mates there say to boot on disk2:d, but after a whole day trying different things I still got a Data Access Error.

Steps used:
make disk:
$ qemu-img create -f qcow2 sunos4.img 4G

Start emulation:
$ qemu-system-sparc -L . -m 256 -hda sunos4.img -cdrom sunOS4.iso -M SS-5 -boot d -bios ./ss5.bin -nographic -serial telnet:,server

$ telnet localhost 3000

<starting OBP> which end by:

sunOS4.iso: created from a bootable Solaris 1.1.2 CD.

I tried several things without success like using the real CD drive of the hsot computer, another CD Solaris 9 etc...
Any help would be greatly appreciate.

Thanks for your time,
sorry if the answer is trivial.
