Benefit of using ROM Emulator and debugging on VT8623/VT8235

[Andrew Ip]

Hi,

I ask those who are using ROM emulator for developing
LinuxBIOS.  What is the benefit of using it besides flashing romimage?
Is it possible to do any code tracing?  At the moment, I'm having
hard time to trace an interrupt problem on vt8623/vt8235(similar
to EPIA-M) where Award'USB works but LinuxBIOS doesn't.  However,
both has the same IRQ assignments.  Furthermore, same code works
on EPIA-M with proper IRQ settings.  Any suggestion on debugging
tools?  Thanks.
