For example, to set the console resolution to 1280x1024@76Hz,

type the following:

ok nvedit

0: : video-timing " 1280, 384, 32, 64,

1024, 43, 3, 8, 135000000, 0" ;

1: <ctrl-c>

ok nvstore

ok setenv use-nvramrc? true

ok reset-all

NOTE: The syntax is very important. The spaces must be

present exactly as they appear in the example.

NOTE: The last three commands enable the NVRAM. Without

these lines, the changes you make with nvedit will be ignored.
