Switching from CD-RW to CD without kernel reboot

[Burn Alting]

Hi Peoples,

I'm a little bit lazy, so will ask here before searching ....

I am running RH7.2 but with a 2.4.19 kernel.org kernel with an IDE CD-RW 
attached.

What I want to do is to burn CD-RW's for backup or just read off the CD. Is 
there a simple way to configure the kernel to be able to switch between 
burning cd's (cdrecord etc) and just reading CD's WITHOUT having to reboot 
the kernel (at present I boot a kernel - lilo.conf/grub.conf with a parameter 
"hdc=ide-scsi" if I want to burn CD's or with this if I just want to mount a 
CD)

Thanks in advance

Burn
