Please stop sending all the HTML crap to FreeBSD lists!

As to your problem, it's probably BIOS. Most ThinkPads, including the
600X, use a DOS utility, PS2, to configure BIOS. Only a very few
things can be configured from the startup BIOS screen. PS2 is
available as a bootable floppy image from the IBM web site. Look for
"DOS Configuration Utility" in downloads.

"ps2 ?" will get you started. There are LOTS of APM options including
disk spin-down. I have my system configured to spin down the disk
after a minute when on battery power and that works OK. I have it
leave the disk spun up when plugged into AC power.
