Problem with FreeBSD 9 Beta 3 dvd

[James Mansion]

I thought I'd try this on a box I'm trying to prep as a NAS, since 
Illumos doesn't seem to recognise the Marvell ethernet.

The box has one of the new AMD E350 chips etc.  Drives 0 to 3 are SATA 
drives, drive 4 is the eSATA drive for boot.  I have a USB DVD reader, 
which has boot priority - normally this system does not have a dvd.

Mandrive boots OK and sees all the hardware. Illumos was fine except for 
the ethernet.

On boot I get:

CD Loader 1.2

Building the boot loader arguments
Looking up /BOOT/LOADER... File not found
Looking up /boot/loader... File not found
Boot failed

A FreeBSD 8.2 'boot only' disk got me to the point where it had 
initalised the disk slices and wanted to connect to an FTP source.  
Which it couldn't see - not sure why yet.  DHCP had configured it OK and 
a Mandrive live disk was fine including surfing the web etc.

Anyhow - my concern in this report is whether the Beta 3 disk is loading 
USB mass storage drivers and doing what it needs to boot from a USB drive.
