Open your menu.lst file:
-------------------------------
sudo nano /boot/grub/menu.lst
-------------------------------
And find the entry you normally use to boot with and go to the line that begins with "kernel", it should say something like this:
------------------------------------------------------------------
kernel /boot/vmlinuz-2.6.15-26-386 root=/dev/hda5 ro quiet splash
------------------------------------------------------------------
Add a "vga=" option to the end of the line, and put in the code from the table above. So if you want 1024x768 at 16 bit color at command line, add "vga=0x317" to the end of your kernel parameters.
Now,
save the file, and it will take effect when you
restart.
