Question Tablet Host rejecting PXE Config

I have a small PXE server running on CentOS 5.6 which has been working well with my Dell and HP hosts. Recently i got a tablet that i will need to configure along with 50 more. I wanted to image it and that is what i set up my PXE server for.

When the IconiaTab 500 boots it get passed DHCP and then says:
PXE-T01: File not found
PXE-E3B: TFTP Error - File not found
So i turn on verbose logging for tftp to get more information:

service tftp
        socket_type             = dgram
        protocol                = udp
        wait                    = yes
        user                    = root
        server                  = /usr/sbin/in.tftpd
        server_args             = -s /tftpboot -v
        disable                 = no
        per_source              = 11
        cps                     = 100 2
        flags                   = IPv4
Which give me the following in /etc/varlog/messages

Aug 13 11:20:52 kanpxe in.tftpd[15927]: RRQ from filename pxelinux.0
Aug 13 11:20:52 kanpxe in.tftpd[15927]: tftp: client does not accept options

I'm barely a gifted amateur when it comes to this. Im trying to bring more into the business but i dont have
to configure it much so what little i know usually goes into the voids of my memory. I mostly do Windows.

I managed to fix it. The larger part of the issue was whatever file the tablet was trying to pull down. I edited my config file to include a map file "-s /tftpboot -vvv -m /tftpboot/".

The contents of my map file are as such
e ^[a-zA-Z0-9].*$
r .* pxelinux.0

The explanation and source are from here

On another note i had some issues with input devices which i found solutions for here:
