Re: [coreboot] Bios Debugging

Hi Jordan,

was just skimming over it today. I think I'll change my mind 
and claim the opposite: great product. I wasn't aware there is
also a full release. Tomorrow I will have a closer look at this
product but it looks really impressing so far. Thanks for 
insisting!!!

Hans :-)

What was missing from these emulators?  SimNow was designed specifically to
develop firmware images.  What did you find lacking?

And please don't get me wrong - SimNow isn't perfect.  I was
asking to figure out what you thought could be better.
I am trying to encourage more SimNow users, and I will gladly
take anything I can send back to the developers.
