Opteron / Tyan motherboard fault on boot.

[Dave Belfer-Shevett]

We're in the process of deploying Linuxbios to boot a cluster of Opteron
based blade servers.  I built a new kernel, put it in /tftpboot after
using:

mkelf-linux --rootdir=rom --ip=rom ./bzImage > vmlinuz.tyan

and cycled the blade.  Wen booting, I get:

Searching for server (DHCP)
Me: 192.168.1.200, Server: 192.168.1.200, Gateway 192.168.1.1
Loading 192.168.1.200:vmlinuz.tyan (ELF)... done

LinuxBIOS-1.1.62.0_Fallback [date date] starting...
Unknown Trwt

Looking at an old message to this list, there's this snippet:
http://www.mail-archive.com/linuxbios@clustermatic.org/msg03174.html

where the following line(s) are, in set_Trwt()...
        if ((clocks < DTH_TRWT_MIN) || (clocks > DTH_TRWT_MAX)) {
                die("Unknown Trwt");
        }

What is this, and why is it happening?  Is there a patch needed for LinuxBIOS
to work properly on modern Opterons?

Thanks, I'm in dire straights here, any help would be appreciated.
