Debian Woody Installation Woes

I am trying to install Debian 3.0_R1 onto an old PC of mine. I am getting a strange error I’ve never seen before even tho’ I have successfully installed Debian several times before. Here is the boot prompt and the subsequent error message:

boot: linux
loading /install…
loading idepci.bin…
ready

Uncompressing linux…

invalid compressed format (err=2)

–System halted
Does anyone have any idea what this means, how I fix it and why it’s happening?
Thanks in advance.
