UT2k4 | Can not install with multiple *.isos | issue may be export SETUP_CDROM=
 

Kernel: 2.6.22.14-72.fc6
Default mount point for physical discs is:
/dec/hdc /media/gametitle

Note:
All game cds were copied to hard drive (games/*.iso) via the following command: (substituted CD# respectively)

mkisofs -v -o UT2K4_CD1.iso /media/gametitle

The following was performed:

(1) Copied installer "linux_in.sh," from CD1 to home directory.
(2) Executed installer from home directory via:
$sh linux_in.sh

--At this point I was asked to insert CD2--

(3) Executed the following to mount contents of CD2:
mount -o loop UT2K4_CD2.iso /media/ISO0/

(4) Executed the following to point to contents of CD2:
export SETUP_CDROM=/media/ISO0/

--At this point, after being asked to insert CD2, I clicked "Continue" (within installer dialog window)--

Nothing happens, the same installer dialog window appears stating "Continue" or "Cancel" for CD2.

What am I overlooking in regards to the "export SETUP_CDROM" command? The above syntax should work, correct?
