A multi-core single-CPU system (yours) is virtually identical to a |
12 |
single-core multi-CPU system. I would use MAKEOPTS="-j2" or higher |
13 |
(basically, twice what you would do for a single-processor system) in |
14 |
your make.conf to take advantage of all that parallel processing |
15 |
power. Use the normal CFLAGS and CXXFLAGS, there aren't any special |
16 |
options for multiprocessor systems there. When you compile your |
17 |
kernel, be SURE to include SMP (symmetric multi-processing) support |
18 |
to let the kernel use both cores. |

SATA hard drives, if supported natively by the southbridge, require |
21 |
no extra drivers. Since your motherboard must be relatively new, |
22 |
this is your case. If they aren't supported natively, one of the |
23 |
various sata_* modules will autoload and handle it. They might be |
24 |
enumerated as SCSI devices, though (/dev/sd* rather than /dev/hd*), |
25 |
but I believe this is perfectly normal. |
