epia800 direct vga working

[Nathanael Noblet]

I have a few questions regarding the changes you made. I have an 
epia800 board. I altered the epia.config / HOWTO instructions to boot 
filo. Once that worked I added to the filo payload the vga bios 
extracted from the normal bios while running. Now I've applied this 
patch and I'm trying to figure out the differences between the two. The 
main difference as I see it is that you use the linux /path/to/linux 
command and I'm trying to do the payload /path/to/filo+vga... I'm 
wondering if these two things are compatible? I'm also wondering if I 
NEED the vga bios extracted still? I'd rather not alter the setup to 
make it boot from a kernel dd' to the hardrive as I like the fact that 
filo allows me to boot whatever kernel I feel like. Could you give me a 
hand so I can alter this. I've looked around and I'm trying to figure 
out what to change in my config...
