HP Pavilion (P7-1145) w/ HIB_707.ROM v7.07 BIOS, Hitachi HDS72101oCLA632 Disk,
SATA Emulation is AHCI
>Description:
On re-boot after installing FreeBSD 9.0 (with the installation CD removed, of course), BIOS reports (I paraphrase) no bootable disk or defective drive.

If I subsequently reboot the installation CD, take the <shell> option in the install program, and use the disklabel program, first with '-w', and then with '-B', and then reboot (after removing the CD), the system boots, but not correctly (at least not as I would expect) because the "boot:" prompt apppears.
