Video Error - Undefined Mode on boot

First i'm not sure if this should be here or in newbie, I don't know if it's a slackware related problem or just a general issue.

But what's happening is when I boot get this message
You passed an undefined mode
Hit <ENTER> to see availible modes or <SPACE> to continue. Or wait 30 seconds.
I was just hitting space because I didn't want to break anything. I looked through rc.d to see if I could find what was causing the error but I couldn't figure it out.

I have tried some of the modes and found one that works for me but how to I make that selection permanent?

Edit: This is happening immedatly at boot.
Lading Linux.................................
BIOS check sucessful
You passed an undefinded mode
Hit <ENTER> to see availible modes or <SPACE> to continue. Or wait 30 seconds.

When you hit enter what video mode did you pick that worked? It may be entered in /etc/lilo.conf if the vga mode is what you are talking about. When you make change to lilo remember to run /sbin/lilo. Review man lilo for more help.

Thanks for the info. So I went into lilo.conf and found the mode set to vga=norma, so I changed it to VESA vga. I ran /sbin/lilo and rebooted. No change except where it used to say vga it now says VESA vga.

The options I get when I hit Enter.
Video Adapter: VESA VGA
Mode:      COLSxROWS
0  0F00     80x25
1  0F01     80x50
2  0F02     80x43
3  0F03     80x28
4  0F04     80x30
5  0F05     80x34
6  0F06     80x60
I've been using option 4. Should I add this to Lilo somewhere? I didn't have much time yesterday to look at the .conf to see if there was a place for it.

This is the Slackware forum and you're replying on a post that is over 10 years old. It is not likely the problem in this thread is related to your issue, so it'd probably be best for you to create your own thread in the Ubuntu/Kubuntu/Debian forum (not sure which are there and what the best one would be).
