Leo's monitor problem revisited, hex to mode-line converter

[Brian Kelsay]

I found this info about mode numbers on the DamnSmall Linux forums.  I hope the spacing didn't get 
too mess up by this useless mail program called Groupwise.

2) If you're booting from HDD, you don't get to manually enter a parameter, to set the system to do 
this, you have to edit the lilo.conf file. Find the line 'vga=<somenumber>'. Change <somenumber> to 
whatever mode you feel comfortable with below:

Use the Non-Hex Numbers, I have included a conversion chart.

Save the file, and at the prompt run 'lilo' then reboot and all should be well

To reset back to normal change the 'vga=<number>' to 'vga=normal'.
