Use the executable @file{qemu-system-sparc} to simulate a SparcStation 5
|
| 1944 | 1945 |
or SparcStation 10 (sun4m architecture). The emulation is somewhat complete. |

SMP up to 16 CPUs is supported, but Linux limits the number of usable CPUs |
|
| 1947 |
to 4. |

The number of peripherals is fixed in the architecture. Maximum memory size |
|
| 1972 |
depends on the machine type, for SS-5 it is 256MB and for SS-10 2047MB. |
