Dear list readers,
I am having a problem with pxe loader on FreeBSD 9.0 i386 release. No
matter what value I put for DHCP option 017 (Root Path) in Microsoft
DHCP server, pxe always sets root path:
pxe_open: server path: /
I've read src/sys/boot/i386/libi386/pxe.c as instructed in handbook, and
i learned there that root path is a failover value which gets set if no
valid value is supplied by DHCP server. At first i thought that
Microsoft DHCP does not send it but i confirmed with windump it does:

I do not understand code well enough to fix it, or at least send
pxeloader static value of /b/tftpboot/FreeBSD/install/, so if someone
would instruct me how to do it i would be very grateful.
Thank you in advance for your help.
