Video Mode Method

At the ok prompt in Boot PROM mode, the screen resolution can be easily set on the PGX32 cards by using one of the 34 preinstalled resolution modes. These resolution settings are identified by video modes 0-33 (Table 6-3).

Note -

Use video modes 0-25 to select a screen depth of 24 bits, or video modes 26-33 to select a screen depth of 8 bits.

Note -

See "Using nvedit to Modify NVRAM" for a description of nvedit commands.

For example, to set the screen resolution to 1024 x 768 at 60Hz, video-mode 8, type:

ok nvedit
  0: 8 value video-mode  1: <ctrl-c>
ok nvstore
ok setenv use-nvramrc? true
ok reset

Note -

The last three commands enable the NVRAM. Without these lines, the changes you make with nvedit will be ignored.
