Booting from CD, install from USB?

Hoi girls n guys,
i've got a problem which i am unable to solve, searched the web and the forums already but couldn't find anything related to it.

The Problem ... :
i've got an old laptop ( can not boot from usb ) on which i try to install openSuSE 10.2, i have got the installation dvd but the laptop hasn't got a dvd drive. so i've created an image, copied it to my usb stick, downloaded the mini-boot-image, burned it to cd, plugged the stick in, booted from cd, everything fine until i have to specify the installation source. now i hit "alt + f9" but i can't mount the usb device.
( i tried mount -t usbdevfs /proc/bus/usb ) and get the error message: "Cannot read /etc/fstab", well no surprise it ain't there.

Is what i'm trying possible at all? Or should i download 3.16 GB again, this time as CDs? [ i had the dvd-image before i got the laptop ... ]

Edit: It hasn't got a network card aswell ...

cheers for your help.

There is a method to boot cd/dvd iso images from the hard drive. If you have spare room on the drive to create a small partition just for the image, it can be made to boot from hard drive. I found this in an article at ArchLinux (copied it months ago and don't have the URL):

I've not been able to boot a hard disk partition containing the Arch iso with grub, instead the iso must first be unpacked to an ordinary partition. This is still quicker than burning a CD:
1) Format the spare partition and (making or using a suitable mount point) mount it:
mkreiserfs /dev/hda12
mkdir /mnt/archCD
mount /dev/hda12 /mnt/archCD

2) Mount the Arch iso file (making or using a suitable mount point):
mkdir /mnt/tmp
mount -o loop arch-0.7.iso /mnt/tmp

3) Copy from the iso to the spare partition:
cd /mnt/tmp
cp -a * /mnt/archCD

4) then modify /boot/grub/menu.lst
title ArchCD
kernel (hd0,11)/isolinux/vmlinuz root=/dev/hda12 BOOTMEDIA=cd
initrd (hd0,11)/isolinux/initrd.img
You could try that on the hard drive, or adapt these instructions for the USB stick. Whether or not it would work on the USB stick depends on the point (after power on) that the files/filesystem on the USB stick becomes available.

create a folder as mount point. example:

mkdir /usb_flash

then type:

mount -t fstype /dev/sda1 /usr_flash

fstype should be the type of the filesystem. example: ext2, ext3, vfat
oops! i think i must have misinterpreted your question. my apologies.

Cheers for your help.

I tried your suggestion first dark_angel and i get the error message:
"mount: Mounting /dev/sda1 on /usr_flash failed: No such device"

for fstype is used: usbdevfs

Now i had a look at my harddisk size which is about 3GB, which the dvd image being 3.16 GB in size i sadly can't use the option to install from hdd.
