Question BIOS wont boot from cd-rom, what to do?

The 486 that I was talking about in the last thread that I posted won't boot from a CD-ROM, and since it can't, I have no idea on how to install Linux on it.

Is there any kind of program that can go on a floppy that a computer can boot off of, and then tell the computer to boot from the CD-ROM?

You can boot from a floppy. I suppose the 486 is up and running,or you have another machine around, what you need to do is
dd if=/mnt/cdrom/path/to/boot.img of=/dev/fd0 bs=1440k
At least it works in linux, sorry I have no experience creating a boot floppy from within windows or dos, but I believe there is a rawrite.exe or something along these lines.

Boot into DOS or Windows. Insert the CD into the drive and a blank floppy into its drive. Look on the CD for a dosutils directory, where you will find rawrite.exe or rawritent.exe. Then look on the CD for an images directory, where you will find a file called cdrom.img. This is an image of a floppy, not a file -- you cannot just copy it to a floppy. Use rawrite, or rawritent, interactively to write the cdrom.img to the floppy.

Set the 486 to boot from the floppy drive. Put the newly written floppy into the 486's floppy drive and the CD into the 486's CD drive and boot that system. The files written to the floppy will set up a ram drive in the 486's memory and will then call on the CD to do the install.

That is a beautiful explanation jglen490 . I still remember when that was the only way to install linux a couple of years ago. Linux has come a long way, and gets better by the second
