poweredge does not boot from cd

I have a running system (SuSE8.1) on a Dell poweredge 500sc. This machine's BIOS for whatever reason does not see the cdrom-drive at hdd, making it impossible to boot from CD. I want to boot from the cd, because I want to install 9.2 on this thing. Is it possible to enter a line in grub's menu.lst, so that i can boot the cd and install?? -- L. de Braal BraHa Systems NL Terneuzen T +31 115 649333 F +31 115 649444
