[LinuxBIOS] Extraction of vga bios from .BIN file?

[Eric Poulsen]

Okay,

I tried awardeco, and it DOES NOT list the VGA ROM, but CBROM (under the 
"dosbox" emulator) worked well.

Only one thing -- the extracted VGA ROM is _exactly_ 64000 bytes 
(instead of 65536) -- do I need to pad it out (with zeros?) before 
concatenating it with LinuxBIOS to achieve the final burnable image?
