The QEMU project is currently considering to move its bug tracking to another 
system. For this we need to know which bugs are still valid and which could be 
closed already. Thus we are setting older bugs to "Incomplete" now.
If you still think this bug report here is valid, then please switch the state 
back to "New" within the next 60 days, otherwise this report will be marked as 
"Expired". Or mark it as "Fix Released" if the problem has been solved with a 
newer version of QEMU already. Thank you and sorry for the inconvenience.

** Changed in: qemu
       Status: New => Incomplete

  qemu-system-sparc w/ SS-20 ROM does not add processors

Status in QEMU:

Bug description:
  When booting a SPARCstation-20 with the original ROM, qemu does not
  set the number of processors in a way that this ROM can understand it,
  and the ROM always reports only 1 processor installed:

   ~/qemu  /usr/local/bin/qemu-system-sparc -bios ./ss20_v2.25_rom -M SS-20 
-cpu "TI SuperSparc 60" -smp 2 -nographic

  Power-ON Reset

             SMCC SPARCstation 10/20 UP/MP POST version VRV3.45 (09/11/95)

  CPU_#0       TI, TMS390Z50(3.x)       0Mb External cache

  CPU_#1       ******* NOT installed *******
  CPU_#2       ******* NOT installed *******
  CPU_#3       ******* NOT installed *******

      <<< CPU_00000000 on MBus Slot_00000000 >>> IS RUNNING (MID =


  Cpu #0 TI,TMS390Z50 
  Cpu #1 Nothing there 
  Cpu #2 Nothing there 
  Cpu #3 Nothing there 


  SPARCstation 20 (1 X 390Z50), No Keyboard
  ROM Rev. 2.25, 128 MB memory installed, Serial #1193046.
  Ethernet address 52:54:0:12:34:56, Host ID: 72123456.

  (It is necessary use SS-20 since it is the only sun4m model that supports 
512MB RAM, and I can't get Solaris to install on the SS-20 using OpenBIOS.) 

  When booting with OpenBIOS I can't seem to boot any version of Solaris
  though I had heard this did work.  Solaris 8 and 9 do work nicely with
  this ROM, but I am opening this to see if it is possible to fix this
  to allow the original OBP ROM to see multiple processors.
