[LinuxBIOS] Problem Using SimNow Simulator

I'm trying to get started with LinuxBios by using the AMD SimNow hardware
simulator to run LinuxBios on a Serenade board. Once we have success with
simulations, we will try it on real hardware.  The Serenade board is one
of the standard predefined boards that comes with the simulator. Once I
serenade.rom and reference this file as the rom device connected to the
8111(replacing the AMI BIOS file), I reboot but don't get too far into the
Linuxbios, I expected to see recognizable postcodes, such as 0x13 from
c_start.S then 0x80, 0x39, 0x40 etc from hardwaremain(), but port 80 only
between 00 and 0x10. I try to single step from 0xfffffff0 (or 0xfffbfff0)
dont see code that looks like c_start.S. Does something come before this?

I must have built serenade.rom improperly: I did the following,
buildtarget amd/serenade
doneloaded filo.elf
edited serenade/Config.lb to refer to the filo.elf as a payload

Any ideas would be appreciated.
