booting/installing Solaris over HTTP

[sab]

thanks Robin,
I am researching into pxegrub and how i can fetch a miniroot to boot and initiate a build without using DHCP.
I am right now stuck at the following level on a HP Proliant DL380 G5:
======================================================

The network connection is fine. It works perfectly outside of iPXE.
I can see in the webserver logs that the client hits the webserver after a delay with following message and then it stops there:

<CLIENT_IP> - - [14/Jun/2013:18:12:31 -0500] "GET /miniroot/x86.miniroot HTTP/1.1" 200 95524456

I am suspecting it may be something to do with the below error messages being thrown out by ifstat command:
=================================================
[RXE: 439 x "Operation not supported (http://ipxe.org/3c086003)"]
[RXE: 343 x "The socket is not connected (http://ipxe.org/380f6001)"]

=================================================

Since I was using the ipxe.iso file downloaded from http://boot.ipxe.org/ipxe.iso, I figured I will compile my own and try it.
But when i try to compile it on Solaris, here's what it says:
===============================================
bash-3.00# cd ipxe-238050d/src
bash-3.00# make
make: Fatal error in reader: Makefile, line 7: Unexpected end of line seen
===============================================


Here's what happens when I tried "gmake":
===============================================
bash-3.00# cd ipxe-238050d/src
bash-3.00# gmake
/bin/sh: git: not found
/bin/sh: ld: not found
/bin/sh: as: not found
grep: illegal option -- q
Usage: grep -hblcnsviw pattern file . . .
/bin/sh: as: not found
grep: illegal option -- E
Usage: grep -hblcnsviw pattern file . . .

*** It hangs here forever ***
===============================================


These are the packages I have on the system:
===============================================
GNU C - The GNU C compiler 3.4.3
GNU binutils - Binary file utilities 2.15
GNU make - A utility used to build software (gmake) 3.81
SUNWperl584core Perl 5.8.4 (core)
SUNWzlib 11.10.0,REV=2005.01.08.01.09
===============================================

Do you know if this has ever been tried on a Solaris box before?
