CD-RW instalation

Hello to everyone. I'm trying to install my cd-rw. As in many how-to says I did as follow: on /boot/grub/menu.lst I changed the line that start with "kernel" and I have added hde=ide-scsi on modules.conf alias scsi_hostadapter ide-scsi And after this my cd-rom doesn't work at all. I'm runing suse 8.2 on a VAIO laptop. I had troubles before with the cd-rom of this laptop because is a PCMIA cd-rom. WIthout doing those changes the cd-rom works fine as ATAPI and is installed in the /dev/hde/ Does anyone can help me? I want to use my cd-rw under linux. Thanks in advance, and if I'm missing any important information let me know please. Juan
