n/a - OS cannot be installed as it locks up during kernel init stages
Hi Team,

This would be a first ever for me, I've been using FreeBSD for years and NEVER had a case where it would not install for me on a machine, until now..

I should mention that I have tested with the 7.1-BETA2/amd64 as well and get the same results too (so whatever the problem is, obviously exists in there too)

Anyway, enough ranting and raving, I will give the Specifics:

The problem is that when I boot from the FreeBSD CD to install, the kernel gets stuck at:

Trying to mount root from ufs:/dev/md0 

And it will sit there on that indefinitely. The keyboard also appears to be unresponsive (pressing caps lock/num lock produces no LED activity on the keyboard)

The hardware:

Intel desktop board (Model BLKDP45SG) (Info from the vendor is available from )

The board is based on the Intel ICH10R Chipset, and has 4GB of DDR3 memory installed, along with an Intel Core Duo CPU.

The board is unusual to me as it has:

* No IDE connectors (SATA Only)
* No PS/2 Connectors for Keyboard and Mouse (only USB is supported)
* No FDC connector (for floppy)

I am booting from a SATA DVD-ROM drive.

Any ideas on what I can do? If you require more information, please let me know.

Attempt to install either 7.0-RELEASE/amd64 or the 7.1BETA2/amd64 on my hardware.
