Setting cursor position from initial SeaBIOS boot screen + changing cursor color

[Robert Butler]

Good morning/evening/afternoon/night,

As a bit of personal hobby, I've recently started studying SeaBIOS in the
hopes of making it behave in a more "life-like" manner (see: VMware's BIOS).
However,  I seem to be at

a bit of a loss for where to start looking for information on the API that I
can use inside SeaBIOS, though. Can someone point me in the right direction?
Perhaps someone can link

me to an html page (or PDF, even) or something that gives me an idea what I
can use during BIOS initialization?

Is there ANY information out there that I can use while doing this?

I mostly need access to the following:

*  The cursor's x/y position

*  Foreground and background text color

*  Low + Extended memory information

*  Installed disk information

Is the above information even available to me at start up like that?

Thanks in advance!

- Robert
