I just use syslinux. Note: this setup is for installing RH7.1. 7.2
is similar. dhcpd.conf includes (among other things):
subnet 192.168.16.0 netmask 255.255.255.0 {
range 192.168.16.100 192.168.16.120;
allow unknown-clients;
allow bootp;
get-lease-hostnames on;
next-server 192.168.16.1;
filename "/pxelinux.0";
}
You need tftp-server installed and running; /var/tftpboot contains:
-rw-r--r-- 1 tibbs root 440 May 27 2001 boot.msg
-rw-r--r-- 1 tibbs tibbs 773163 May 27 2001 initrd.img
-rw-r--r-- 1 root root 9364 May 27 2001 pxelinux.0
drwxr-xr-x 2 root root 4096 May 27 2001 pxelinux.cfg/
-rw-r--r-- 1 tibbs tibbs 652144 May 27 2001 vmlinuz
./pxelinux.cfg:
-rw-r--r-- 1 tibbs root 191 May 27 2001 default
pxelinux.cfg/default contains:
DEFAULT ks
DISPLAY boot.msg
PROMPT 1
TIMEOUT 500
label ks
kernel vmlinuz
append vga=788 initrd=initrd.img lang= devfs=nomount ks=nfs:master.lab00.math.uh.edu:/usr/local/kickstart/ks.cfg
Note that this needs changing for 7.2; you must at least include the
ramdisk_size parameter or the installation will break in weird ways.
initrd.img and vmlinuz are just copied form the bootnet floppy.
boot.msg is just a warning:

Instructing the network card to try network before disks will result

I don't know what that is; I got a syslinux RPM and installed it to
get pxelinux.0.
