Hi, I'm just about to install gentoo on a dual core Intel CPU machine with a SATA HD. So, essentially, I have two questions. What CFLAGS are recommended for a dual core CPU and what precautions must one take to have the SATA HD recognised by the install media? I don't think the CPU is 64 bit in case you need to know.
A multi-core single-CPU system (yours) is virtually identical to a single-core multi-CPU system. I would use MAKEOPTS="-j2" or higher (basically, twice what you would do for a single-processor system) in your make.conf to take advantage of all that parallel processing power. Use the normal CFLAGS and CXXFLAGS, there aren't any special options for multiprocessor systems there. When you compile your kernel, be SURE to include SMP (symmetric multi-processing) support to let the kernel use both cores.
SATA hard drives, if supported natively by the southbridge, require no extra drivers. Since your motherboard must be relatively new, this is your case. If they aren't supported natively, one of the various sata_* modules will autoload and handle it. They might be enumerated as SCSI devices, though (/dev/sd* rather than /dev/hd*), but I believe this is perfectly normal.
