I currently have Xp on my machine with three partitions,one with XP,Redhat and Mandrake.I tried booting from the CD-rom, but it just goes to XP.Is there a way to make a installation floppy for SuSE?

You'll need to go into your BIOS setup and change the boot order so that the CD-ROM is first.

I have System commander 7 and when I disable it,it boots to XP

I've no idea what "System Commander 7" is or does.

here's how, from the SUSE readme file.

In addition to a boot disk you will also need modules disk 1.

You can create a new boot/install floppy if you have access to either a
running Linux box or a running DOS box.

Choose one of the boot images in this directory according to the list below.

Under DOS, write it to a formatted (i.e. error-free) 1.44MB-floppy using
CD1:/dosutils/rawrite/rawrite.exe.

Under Linux, use a command like

cd /whereCD1isMounted/disks
dd if=./myBestBootImageAccordingToReadme of=/dev/fd0u1440

Now you have a new boot/install floppy which you can use to boot either the
installed system or the rescue system from CD.

----------------------------------------------------------------------------
bootdisk: Standard bootdisk

i386: Fallback bootdisk for i386 and older Cyrix processors.

rescue: Rescue disk

Only a few modules fit on the bootdisk. Therefore three modules floppies
exist. If you do not find the driver for your hardware on the normal disk,
just insert the appropriate modules disk as soon as linuxrc starts.

modules1: USB and file system modules.

modules2: SCSI/RAID/EIDE modules and old (non-ATAPI) CDROM drivers.

modules3: Network, PCMCIA and FireWire (IEEE1394) modules.
