heh, welcome to the wonderful world of slack
the thing with choosing slackware is that you have to be prepared for an insane learning curve. slack is a minimalistic distro, they diliberately didnt do multiple kernels like the other distros, cause a slack user compiles his own anyways.
for compiling the kernel, my best advice is that if you dont know what it is, read the helpfile. (if your using make menuconfig, press ? on an option)
if your having specific issues, post em, people here are super helpful. if its just your dvdrom, it could just be a simple matter of editing /etc/fstab. dont expect everything to be up and running straiight after a slackware install, with my pc anyways i alwas gotta spend a good half hour tweaking stuff. learning what to do to get stuff working took a looooong time, but in doing so, i learned allllllllllllllot about how linux works. just dont give up, slack has alot to offer, not the least being a true understanding of the linux OS
