[syslinux] Comboot API

[Murali Krishnan Ganapathy]

Agreed. It can easily be implemented in C. Another comboot API related 
question.
The "DOS interrupts" which are implemented (a.k.a. the int 21h 
interrupts). It looks like they do not respect display pages.
For example, if I switch the display page (using BIOS int 10h), and then 
use Int 21h to display a string, then under isolinux, it goes to the 
wrong display page, but under DOS (actually DOS box under windows) it 
goes to the right one.

Was this intended?

For the comboot menu, I switch the display page, and display my menu, so 
that once I am done, I can switch the page back and the user will see 
the usual text page. BTW, the code works fine under DOS and running 
under isolinux does not result in any "bad interrupt"!
