VirtualBox LAN boot ROM Size

On this site https://gist.github.com/robinsmidsrod/4001104 it says this about the size:

include/iprt/cdefs.h
1888:#define _64K                    0x00010000

src/VBox/Devices/PC/DevPcBios.h
43:#define VBOX_LANBOOT_SEG            0xe200

src/VBox/Devices/PC/DevPcBios.cpp
1348:                if (cbFileLanBoot > _64K - (VBOX_LANBOOT_SEG << 4 & 0xffff))

$ perl -e 'printf "%x\n", 0x10000 - 0xe200 << 4 & 0xffff'
e000
$ perl -e 'printf "%d\n", 0x10000 - 0xe200 << 4 & 0xffff'
57344
So the conclusion is that the maximum size of a ROM is 0xE000 bytes (= 57344)


Installing the new LAN boot ROM into VirtualBox

See: http://etherboot.org/wiki/romburning/vbox

8086100e.rom is the LAN boot ROM for the Intel PRO/1000 MT Desktop (82540EM) which is the default when you have the VirtualBox Extension Pack installed.

Create a virtual machine ( Here I call it "Hadoop Client" ) and do settings that you want to boot from network
Copy the 8086100e.rom into the directory of that VM
Add the ROM image to the VM config:
Under Linux:

vboxmanage setextradata "Hadoop Client" VBoxInternal/Devices/pcbios/0/Config/LanBootRom 8086100e.rom
Under Windows:

"c:\Program Files\Oracle\VirtualBox\VBoxManage.exe" setextradata "Hadoop Client" VBoxInternal/Devices/pcbios/0/Config/LanBootRom "C:\VirtualBox VMs\Hadoop Client\8086100e.rom"
