) asinstalling Suse Linux 10.0

Hello,
I cannont install Linux because, in spite of changing the BIOS to look to the CDROM first, it won't. The computer is 6 years old, a Pentium III 386, 512mg ram, 60g harddrive, partitioned into 2 30g drives, with XP installed on C. I do have a floppy (3 1/2), as well. Any help would be greatly appreciated...thanks!
Susan
