epia-m vga cromwell bios

Wed Sep 1 13:58:01 CEST 2004

This is actually 2 questions in one.
I've been having some problems getting VGA to work on my epia-m board.  I was able to get etherboot to load the kernel, etc, but when I made the recent changes for VGA, elfboot doesn't like what I did.  I've included a capture of the serial output
and my configuration file.  I also was interested in doing something like the cromwell open-source bios for the Xbox, where vga is fully initialized from the start and a nice graphical screen can be set up to enable booting from etherboot, cd-rom or the hard disk via grub.  My Xbox mod-chip is also 256kb, so I'm guessing it should work.  Here's the serial port capture:
