[OpenBIOS] Help with patch

[Programmingkid]

I want to place vga related code in the vga.fs file, but it just doesn't compile. Here are some of the errors I see:

Error:  File /Users/john/Desktop/openbios/drivers/vga.fs, Line 234.  (Output Position = 1166).  Word  find-device  is not in dictionary.
Error:  File /Users/john/Desktop/openbios/drivers/vga.fs, Line 235.  (Output Position = 1179).  Word  active-package  is not in dictionary.

Is there a way to fix this error?
