OK - thankyou for that, hpa

I originally got mine from:

http://mirror.switch.ch/ftp/mirror/fedora/linux/releases/9/Fedora/i386/iso/Fedora-9-i386-netinst.iso

The sha1sum is:

3b1df20ece05d64c34dd9c64400975b74eded0f2  Fedora-9-i386-netinst.iso

I have also put it on my website, just in case it gets 
updated on the mirrors:

http://www.karsites.net/fedora/9/Fedora-9-i386-netinst.iso

obviously same sha1sum ;)

The Fedora guys are following this thread now. I have put 
the link to your patch on my Fedora bug report:

https://bugzilla.redhat.com/show_bug.cgi?id=450678

I have never built an iso file before, but I'll read up on 
it. My plan was to copy the files from the F9 net-installer 
CD to my hard drive, update them with your patch, and then 
re-make the iso file and burn that back to CD-R. Would that 
work?
