using only the intel controller; 1 ide dvd-rom; post takes 15-20 secs; most of the time used to be spent by the marvell controller; have hdd first in boot order; don't know if your sata drives add that much time or it's something else; try to disconnect everything except the hdd (including usb web cams and what not) to get the best possible post time and start adding them back 1 by 1 and maybe you'll find the culprit
