- SPARC is a family of RISC microprocessors designed and marketed by
- Sun Microsystems, incorporated. They are very widely found in Sun
- workstations and clones. This port covers the original 32-bit SPARC;
- it is old and stable and usually considered one of the "big three"
- along with the Intel and Alpha ports. The UltraLinux project
- maintains both the SPARC32 and SPARC64 ports; its web page is
- available at <http://www.ultralinux.org/>.

Sparc32 does not have a CAS instruction like sparc64. cmpxchg()
is emulated, and therefore it is not completely atomic.

Find out whether your system includes a PCI bus. PCI is the name of
a bus system, i.e. the way the CPU talks to the other stuff inside
Only choose N if you know in advance that you will not need to modify
OpenPROM settings on the running system.
