Going FROM redhat9 TO Slackware10 Help Burning ISO.

I feel so dumb asking this question, but I just CAN'T figure out how to install slackware 10.
I have downloaded the install iso's disk 1 and disk 2. I have wasted 2 disks trying to burn the ISO to them, but I just cant.

I am running Redhat 9 Shrike. Anyhelp would be greatly appreiated, AS SOON AS POSSIBLE, as I am leaving for Wienipeg Folk Fest tommorrow. I would like to get Slack installed before I leave.

Thanks in Advance.

What program are you using to burn the iso's?

Usually there is an option called "burn cd image" or something like that. Not data cd.
