[syslinux] PXELINUX,ISOLINUX and NFS support

[karthik]

Hi,
    I have been using isolinux for couple of months now and has been
working fine. Now i have a scenario where i want to install the isolinux
image from the network.

1) Is PXELINUX the solution for me ?
2) Does PXELINUX apply only for booting and not for installing the
remote machine ?
3) Does PXELINUX support nfs installation instead of tftp ?

Any inputs regarding this would be appreciated.
Regards
Karthik
