[syslinux] Problems with PXELINUX and Redhat 9.0

[Dan Dunham]

I'm trying to boot the Redhat 9.0 install kernel with PXELINUX.  I've
successfully booted previous versions of the Redhat install kernel
using the same hardware and PXELINUX configuration.  I've tried this
with PXELINUX 2.04, 2.03, and 1.75, all with similar results.  I have
attached the PXELINUX output and (hopefully) relevant data below.

I've noticed some other people on this list with the same problem.
I've succesfully booted many different kernels with this exact same
configuration, and this is the first time I've had this problem.  One
thing that might be relevant is that this is the largest kernel image
I've attempted to PXE-boot.  It is 855693 bytes, and is available
here:

ftp://ftp.redhat.com/pub/redhat/linux/9/en/os/i386/images/pxeboot

Thanks for your help,
Dan
