Sanboot Slitaz Live CD

[lstraath]

You could be right about that it could mean UNDI and native driver both be active on the same device will cause trouble.
However i already have issues when chainloading undionly.kpxe-->pxelinux.0+vesamenu.c32-->sanboot livecd.iso

And undionly.kpxe-->sanboot livecd.iso is more stable (read works on more types of hardware).

But i want to use pxelinux for the menu's

Sanboot by the way of a livecd is even with undi incredible fast, thumbs up for ipxe on that one.
