Hello Peter, It isn't stated on your site how to transfer initrd images using PXELINUX. I found out how to do it, but I can imagen that some people won't. Perhaps you could add an clear example like this to your http://syslinux.zytor.com/pxe.php section: ----- To load a linux kernel using an initrd root filesystem add an configuration entry: LABEL linux-install KERNEL vmlinuz APPEND root=/dev/ram0 initrd=rootfs.gz PXELINUX will fetch both the kernel(vmlinuz) and the compressed root filesystem using lftp. After this PXELINUX boots the kernel which mounts the initial ramdisk as root. ----- Also, dhcpd doesn't know the option 'dhcp-class-identifier'. Futhermore, using the statement: append dhcp-parameter-request-list 208, 209, 210, 211; makes the dhcpd to obmit the router option for the clients. I'm not sure if this is (a bug) on the server or client side. Anyway, we now have PXELINUX working at our company and it works great. Thank you for your efforts! Regards, Rene
