[SeaBIOS] Use SeaBIOS as UEFI CSM

[Roderick Klein]

Hello Paul,

I am the president of the Dutch OS/2 VOICE organisation. I have also 
kind of been lurking here look at this possibility. Instead of modiying 
legacy OS'es I was wondering if a UEFI loader could be created with 
SeaBIOS build in. I think I did ask the question once on this list but 
never got a reply. Off to work!

Something I think is very hopefull was this thread:
https://communities.intel.com/thread/51481?start=0&tstart=0

"I have FreeDOS running on Galileo using SeaBIOS as a CSM (Compatibility 
Support Module)."

I am very interested to heat the opinion of other people!
Then again what operating system do your colleagues need or use a 
virtual machine. And how many modern Linux, FreeBSD versions do not 
support UEFI ? Then again if you are running an older OS of an 
application that can be ported.

Best regards,

Roderick Klein
