While having your drive labeled as ad4 strikes me as weird, I don't have enough BSD experience to know if it is a symptom of a problem or not. (I know my drive is on ad4 because the on-board controllers are slower than my add-on card. After a BIOS update booting is no problem. (I initially tried to forcibly disable the on-board controller: now, I ignore it.))

Thank you for your kind reply.

Thank you for the handbook reference, i did read the section.
In fact, there is only one SATA HDD in my laptop.

I've got two identical Compaq Presario C300TU laptops - one
running Gentoo Linux and other "would" run FreeBSD 8.0 (when it gets)

Additionally, from the BIOS i've activated
 . Wireless Radio (Broadcom chipset)
 . Native SATA Controller
 . Realtek Netboot agent

There is only ONE SATA Seagate HDD of 160GB in the system.

Currently, i'm struggling to get the installation work from the
Fixit# command line.

Any suggestions ?


thanks
Saifi.
