Not without modifying the code.

You could include an embedded script which clears the screen before attempting to boot; see http://ipxe.org/cmd/set#notes for instructions on clearing the screen and http://ipxe.org/embed for information about embedding scripts.

After embedding, will i still require this (it's in my embedded script now) on my dhcp server:

dhcp-boot=http://192.168.0.xx/xxxxxx/bootstrap.ipxe

if in the case the chain link in the embedded script is broken, what happens? will the above line serve in dnsmasq serve as backup?

your link also brought me to notice:

make bin-x86_64-efi/808610de.efirom # 64-bit driver ROM

that got me interested in building UEFI pxe.

Do I just type: " make bin-x86_64-efi/808610de.efirom "
and that it would automatically know it has to build a 64bit efi rom based on filename?

###3###
zlib and binutils header files (only needed for EFI builds)
[ebuild R ] sys-devel/binutils-2.21 USE="nls -multislot -multitarget -test -vanilla"
[ebuild R ] sys-libs/zlib-1.2.5-r2

I have an old linux box, which i dont intend to update, will those versions suffice for EFI?

If you have an embedded script, then the control flow (including what to do in the case of failure) is entirely under the control of that script. For example, you could create a script that retries indefinitely:

Code:
#!ipxe
:try_dhcp
dhcp || goto try_dhcp
:try_boot
chain ${filename} ; sleep 1 ; goto try_boot

Yes.

Probably. Try it and see if it builds.

Code:
#!ipxe
:try_dhcp
dhcp || goto try_dhcp
:try_boot
chain ${filename} ; sleep 1 ; goto try_boot

Sorry I'm a little slow,

please tell me if i got the program flow wrong

scenarios:
dhcp -> gets ip -> boots ${filename} -> out of myscript.ipxe
dhcp -> gets ip -> boots ${filename} but fails to find filename -> infinite 1 sec loop attempting to boot ${filename}?
dhcp -> doesn't get ip -> infinite loop till it does?

and filename = http://192.........../bootmenu.ipxe right?

Yes, pretty much. You can find documentation for flow control in scripts at http://ipxe.org/scripting#flow_control.
