This stuff is in. Definitely worked at 0.13 - 0.14 times, but I never had time to check 0.15+. compile my qemu with: git clone git://git.savannah.nongnu.org/qemu.git cd qemu ./configure --target-list=sparc-softmmu make (version 0.13.50) That 2009 blog is outdated: QEMU now lives in git://git.qemu.org/qemu.git and should be at 0.15.93 (1.0-rc3). Compare http://qemu.org for details. CC'ed sparc maintainer and Artyom. Andreas Andesas tks for the info. upgrading to 0.15.1 did not solve the issue.

Ive downloaded the ss5.bin bios (sparc station 5)) I have the solaris disk and i can do the installation but can't get the disk to boot. I can boot from the cd, mount and check the /etc/system file it has the "set scsi_options=0x58" option i set to make it work, still not working: Here is the output: /ok boot disk0:d Boot device: /iommu/sbus/espdma@5,8400000/esp@5,8800000/sd@0,0:d  File and args: SunOS Release 5.5.1 Version Generic [UNIX(R) System V Release 4.0] Copyright (c) 1983-1996, Sun Microsystems, Inc.

Resetting ... / maybe the disk is wrong ive try several disk one following these instructions: 1) qemu-img create -f qcow2 file.qcow2 12G 2) Add -drive file=file.qcow2,unit=3 to your qemu startup 3) Boot single user 4) echo 'disk_type="QEMU12.0G":ctlr=SCSI:ncyl=49152:acyl=0:pcyl=49152:nhead=16:nsect=32:rpm=7200' /etc/format.dat I'd guess these geometry parameters are not correct for your 12G disk. It's strange though that the installer kernel sees different geometry from the normal boot kernel. 5) echo 'partition="QEMU12.0G":disk="QEMU12.0G":ctlr=SCSI:2=0,25165824:0=0,20971520:6=40960,4194304' /etc/format.dat These could also be wrong, but I have no idea what the numbers mean. In order not to mess with all this numbers I used a pre-defined 1.3G disk in the Solaris format utility and created it with dd: dd if=/dev/zero of=$1 bs=10k count=133756 Otherwise, Ignacio, are you sure that disk0 is your root FS disk and not something else? Can you post your qemu command line? qemu-system-sparc -M SS-5 -startdate "2009-12-13" -bios /root/ss5.bin -nographic -hda /root/imagenes/solaris.disk -hdb /root/solaris_2.5.1_1197.iso Thks for your help Artyom. I'll try with a dd, and solaris format utility and I'll let u know Ignacio --         Simplicity is the ultimate sophistication         Ignacio Geli         Implementación y Soporte
