I don't have those BIOS controls I'm afraid.

I decided on an even simpler approach. As I don't really want all the other 
stuff in /var/tmp to evaporate every time I shut down, I put /tmp on 
tmpfs, with this entry in /etc/fstab:
	tmpfs	/tmp		tmpfs	nodev,nosuid,size=85%		0 0

Then I added these entries to /etc/make.conf:
	BUILD_PREFIX="/tmp/portage/build"	# not sure I need this
	CCACHE_DIR="/var/tmp/ccache"	# to make sure it doesn't go looking in /tmp
	PORTAGE_TMPDIR="/tmp"

Where did you find this recommendation? I can't find any reference to it.

Same question.

My SATA disks don't show up on the disk activity LED, but I do have gkrellm 
permanently on my desktop and it shows disk activity. I'll watch it with 
interest  :-)

Thanks for the help.
