also came back with some DNS errors but I was not able to capture them, went by too quickly.

Whats the "filtered" mean in the nmap scan?
Now it is stuck at:

Could not find kernel image: linux
created a boot.msg in /tftpboot (copied from an old pxe boot server, I plan on adding centos51 once I get it going)
0bAvailable boot commands:
0aDOS0f - Start a DOS environment (with tools)
0aFC60f - Start Fedora Core 6 Installer/Updater [see note]
0aMEMTEST0f - Start memtest86
07Pressing <ENTER> will attempt to boot from the local drive
Note: For Fedora notes and options, press F4
append ks=http://10.1.1.66/FC6/core/i386/ks.fc6 initrd=fc6/initrd.img ramdisk_size=8192 selinux=0
"mac address" is the actual mac address, just substituted for privacy
still getting stuck at trying to load pxelinux.cfg
added next-server <10.1.1.66>;
to dhcpd.conf and it gives me the boot menu but it can't find the ks file. Does httpd need to be running in order to server the ks file?
Our old pxe server has httpd running and our location in default to the ks file is:
append ks=http://10.1.1.66/CentOS/5.1/ks/ks.install initrd=centos51_i386/initrd.img ramdisk_size=8192 selinux=0 text
but I get the Error downloading kickstart file:
I always love it when I find a new error. At least this one gives me hope.
checked /var/log/messages and see this when I try to boot from the PC i want to install.
in.tftpd: tftp: client does not accept options.
its followed by a few DHCP messages
then on the PC that fails to load it crashes:
loaded received SIGSEGV! BACKTRACE
install exited abnormally.
umounting some filesystems
you may safely reboot your system.
At least now it gets me to my boot menu and loads the ata_pixx driver, then probes the ethernet card, then crashes.
