FreeBSD PXELINUX

*FreeBsd PXELINUX

เอกสารฉบับนี้เป็นการ install โดยใช้ sysinstall ซึ่งถูกแทนที่ด้วย bsdinstall ใน freebsd version 9

# install syslinux


yum install  xinetd tftpd-server syslinux dhcp vsftdp -y
cd /usr/shared/syslinux 
cp pxelinux.0 menu.c32 memdisk mboot.c32 chain.c32 /tftpboot

yum install xinetd tftpd-server syslinux dhcp vsftdp -y

cd /usr/shared/syslinux

cp pxelinux.0 menu.c32 memdisk mboot.c32 chain.c32 /tftpboot

FreeBsd 8.x use sysinstall for install freebsd.
