PXE tftp - double boot

[Vagner]

Hello!
Tell me please, how can i boot from tftp server (throught pxe) several
copies FreeBSD from different path (For example: /pxeroot/freebsd1 and
/pxeroot/freebsd2)?  
I see variale rootpath at source sys/boot/i386/libi386/pxe.c. I
compiled several pxeboot files (there i changed variable rootpath from "/" to "/pxeroot/freebsd[1-2]"), and i booted this files throught pxelinux.
Booting stoped at boot kernel.
