If you boot the FC4 CD or DVD installer and see an error something like 
the above text or picture, then your motherboard chipset may be affected 
by the syslinux crash bug. This bug reportedly happens most often on 
Intel Pentium4 or Nocona chipsets 845, 865, 875, 915, 925, 945, 955, and 
very rarely on some AMD64 motherboards.

Simple Workaround
The majority of users can easily workaround this problem by using the 
"garbage" workaround. Simply boot the CD/DVD, and at the first prompt 
type any line of garbage (the string "garbage" works fine), then ENTER. 
At this point you can use any regular installer command to start the 
installer, or simply ENTER.

For some rare users the "garbage" workaround does not work. For these 
users, this 6MB sized i386 boot.iso replacement should theoretically 
work. Note that boot.iso is only usable with a network-based install.
