Video Mode not Supported ...Arrghhhh!

So people, this is what happened:

I have an old Dell Dimension( P75) running Redhat 7.3 as my firewall on a 17" monitor. I just bought the Daewoo 19" LCD (sweet monitor) and decided to bump the resolution up from 1024X768 and guess what happened?

I get :"video mode not supported" and I can't do anything at all.

I know you can boot off the cd and use the "linux rescue " option, but the thing is this Dell is so old it does not boot from CD only Floppy.

Is there a way to make a floppy boot disk that will allow me to boot into rescue mode to run Xconfigurator? That failing is there a way to stop Linux from booting into run level 5 (X windows) and boot into run level 3 (Comand Line ) so I can get into the system?

Help Please..

I'm not sure about Red Hat, but Mandrake will allow you to enter "Interactive startup" by pressing i at start up (it tells you about this), after that you can choose which services you want to run, and obviously you could choose not to run dm, and then you'd get into runlevel 4 or 3. Your computer may actually allow you to boot from CD-ROM, check the BIOS for the boot order, and make sure CD-ROM is above hard drive. I'm not aware of a bootable floppy that would read linux partitions, but if you had another computer, you would be able to compile your own (slim) kernel and then throw it on a floppy disk to make it bootable.

Barring that, I'm wondering how you originally installed Red Hat on the computer, did you do an NFS install or what?

I think this is what you need.

You will need to boot to a dos prompt and use teh rawwrite program that is on the CD to create a boot floppy.
