# @OptionDescription@
#       User interaction options:
#
#       -DASK_BOOT=n
#                       Ask "Boot from (N)etwork ... or (Q)uit? " 
#                       at startup, timeout after n seconds (0 = no timeout).
#                       If unset or negative, don't ask and boot immediately
#                       using the default.
#       -DBOOT_FIRST
#       -DBOOT_SECOND
#       -DBOOT_THIRD
#                       On timeout or Return key from previous
#                       question, selects the order to try to boot from
#                       various devices.
#                       (alternatives: BOOT_NIC, BOOT_DISK,
#                        BOOT_FLOPPY, BOOT_NOTHING)
#                       See etherboot.h for prompt and answer strings.
#                       BOOT_DISK and BOOT_FLOPPY work only where a driver
#                       exists, e.g. in LinuxBIOS.
#                       They have no effect on PCBIOS.
#       -DBOOT_INDEX    The device to boot from 0 == any device.
#                       1 == The first nic found.
#                       2 == The second nic found
#                       ...
#                       BOOT_INDEX only applies to the BOOT_FIRST.  BOOT_SECOND 
#                       and BOOT_THIRD search through all of the boot devices.
#       -DBAR_PROGRESS
#                       Use rotating bar instead of sequential dots
#                       to indicate an IP packet transmitted.
#
#       Boot order options:
#
#       -DBOOT_CLASS_FIRST
#       -DBOOT_CLASS_SECOND
#       -DBOOT_CLASS_THIRD
#                       Select the priority of the boot classes
#                       Valid values are:
#                               BOOT_NIC
#                               BOOT_DISK
#                               BOOT_FLOPPY
#       BOOT_DISK and BOOT_FLOPPY work only where a driver exists,
#       e.g. in LinuxBIOS.  They have no effect on PCBIOS.
#
#       Boot autoconfiguration protocol options:
#
#       -DALTERNATE_DHCP_PORTS_1067_1068
#                       Use ports 1067 and 1068 for DHCP instead of 67 and 68.
#                       As these ports are non-standard, you need to configure
#                       your DHCP server to use them. This option gets around
#                       existing DHCP servers which cannot be touched, for
#                       one reason or another, at the cost of non-standard
#                       boot images.
#       -DNO_DHCP_SUPPORT
#                       Use BOOTP instead of DHCP.
#       -DRARP_NOT_BOOTP
#                       Use RARP instead of BOOTP/DHCP.
#
#       -DUSE_STATIC_BOOT_INFO  
#                       Use static ip insted of dynamic protocols
#                       When USE_STATIC_BOOT_INFO is defined, the following
#                       must also be defined:
#                       -DSTATIC_CLIENT_IP
#                       -DSTATIC_SUBNET_MASK
#                       -DSTATIC_SERVER_IP
#                       -DSTATIC_GATEWAY_IP
#                       -DSTATIC_BOOTFILE
#
#       -DSTATIC_CLIENT_IP=\"1.2.3.4\"
#                       Static client IP address.  Requires -DUSE_STATIC_BOOT_INFO
#                       be set to be used.
#       -DSTATIC_SUBNET_MASK=\"255.255.255.0\"
#                       Static subnet address.  Requires -DUSE_STATIC_BOOT_INFO
#                       be set to be used.
#       -DSTATIC_SERVER_IP=\"1.2.4.5\"
#                       Static server IP address.  Requires -DUSE_STATIC_BOOT_INFO
#                       be set to be used.
#       -DSTATIC_GATEWAY_IP=\"1.2.3.254\"
#                       Static gateway IP address.  Requires -DUSE_STATIC_BOOT_INFO
#                       be set to be used.
#       -DSTATIC_BOOTFILE=\"tftp://1.2.4.5/pxelinux.0\"
#                       Static gateway IP address.  Requires -DUSE_STATIC_BOOT_INFO
#                       be set to be used.
#
#       -DEXIT_ON_FILE_LOAD_ERROR
#                       Exit Etherboot if unable to load the requested boot file
#
#       -DREQUIRE_VCI_ETHERBOOT
#                       Require an encapsulated Vendor Class Identifier
#                       of "Etherboot" in the DHCP reply
#                       Requires DHCP support.
#       -DDHCP_CLIENT_ID=\"Identifier\"
#       -DDHCP_CLIENT_ID_LEN=<Client ID length in octets>
#       -DDHCP_CLIENT_ID_TYPE=<Client ID type>
#                       Specify a RFC2132 Client Identifier option, length and type.
#                       Requires DHCP support.
#       -DDHCP_USER_CLASS=\"UserClass\"
#       -DDHCP_USER_CLASS_LEN=<User Class length in octets>
#                       Specify a RFC3004 User Class option and length. Use this
#                       option to set a UC (or multiple UCs) rather than munge the
#                       client Vendor Class ID.
#                       Requires DHCP support.
#       -DALLOW_ONLY_ENCAPSULATED
#                       Ignore Etherboot-specific options that are not within
#                       the Etherboot encapsulated options field.  This option
#                       should be enabled unless you have a legacy DHCP server
#                       configuration from the bad old days before the use of
#                       encapsulated Etherboot options.
#       -DDEFAULT_BOOTFILE=\"default_bootfile_name\"
#                       Define a default bootfile for the case where your DHCP
#                       server does not provide the information.  Examples:
#                         -DDEFAULT_BOOTFILE=\"tftp:///tftpboot/kernel.nbi\"
#                         -DDEFAULT_BOOTFILE=\"tftp://1.2.4.5/lts/pxelinux.0\"
#                       If you do not specify this option, then DHCP offers that
#                       do not specify bootfiles will be ignored.
#
#       NIC tuning parameters:
#
#       -DALLMULTI
#                       Turns on multicast reception in the NICs.
#
#       Boot tuning parameters:
#
#       -DCONGESTED
#                       Turns on packet retransmission.  Use it on a
#                       congested network, where the normal operation
#                       can't boot the image.
#       -DBACKOFF_LIMIT
#                       Sets the maximum RFC951 backoff exponent to n.
#                       Do not set this unreasonably low, because on networks
#                       with many machines they can saturate the link
#                       (the delay corresponding to the exponent is a random
#                       time in the range 0..3.5*2^n seconds).  Use 5 for a
#                       VERY small network (max. 2 minutes delay), 7 for a
#                       medium sized network (max. 7.5 minutes delay) or 10
#                       for a really huge network with many clients, frequent
#                       congestions (max. 1  hour delay).  On average the
#                       delay time will be half the maximum value.  If in
#                       doubt about the consequences, use a larger value.
#                       Also keep in mind that the number of retransmissions
#                       is not changed by this setting, so the default of 20
#                       may no longer be appropriate.  You might need to set
#                       MAX_ARP_RETRIES, MAX_BOOTP_RETRIES, MAX_TFTP_RETRIES
#                       and MAX_RPC_RETRIES to a larger value.
#       -DTIMEOUT=n
#                       Use with care!! See above.
#                       Sets the base of RFC2131 sleep interval to n.
#                       This can be used with -DBACKOFF_LIMIT=0 to get a small
#                       and constant (predictable) retry interval for embedded
#                       devices. This is to achieve short boot delays if both
#                       the DHCP Server and the embedded device will be powered
#                       on the same time. Otherwise if the DHCP server is ready
#                       the client could sleep the next exponentially timeout,
#                       e.g. 70 seconds or more. This is not what you want.
#                       n should be a multiple of TICKS_PER_SEC (18).
#
#       Boot device options:
#
#       -DTRY_FLOPPY_FIRST
#                       If > 0, tries that many times to read the boot
#                       sector from a floppy drive before booting from
#                       ROM. If successful, does a local boot.
#                       It assumes the floppy is bootable.
#       -DEXIT_IF_NO_OFFER
#                       If no IP offer is obtained, exit and
#                       let the BIOS continue.
#                       The accessibility of the TFTP server has no effect,
#                       so configure your DHCP/BOOTP server properly.
#                       You should probably reduce MAX_BOOTP_RETRIES
#                       to a small number like 3.
#
#       Boot image options:
#
#       -DTAGGED_IMAGE
#                       Add tagged image kernel boot support (recommended).
#       -DAOUT_IMAGE
#                       Add a.out kernel boot support (generic).
#       -DELF_IMAGE
#                       Add generic ELF kernel boot support (recommended).
#       -DEL64F_IMAGE
#                       Add generic ELF64 kernel boot support (useful for > 4GB disks).
#       -DWINCE_IMAGE
#                       Add the ability to boot WINCE.... now only sis630 OK!
#       -DPXE_IMAGE
#                       Add the ability to boot PXE NBPs.  Requires
#                       PXE_EXPORT.  Currently not supported on
#                       anything other than i386
#       -DFREEBSD_PXEEMU
#                       Add the ability to boot PXE images... only FreeBSD supported
#       -DIMAGE_MULTIBOOT
#                       Add Multiboot image support (currently only
#                       for ELF images).
#                       Without this, generic ELF support is selected.
#       -DIMAGE_FREEBSD
#                       Add FreeBSD image loading support (requires at least
#                       -DAOUT_IMAGE and/or -DELF_IMAGE).
#       -DFREEBSD_KERNEL_ENV
#                       Pass in FreeBSD kernel environment
#       -DAOUT_LYNX_KDI
#                       Add Lynx a.out KDI support
#       -DMULTICAST_LEVEL1
#                       Support for sending multicast packets
#       -DMULTICAST_LEVEL2
#                       Support for receiving multicast packets
#       -DDNS_RESOLVER
#                       Support for resolving hostnames in bootfile name (experimental)
#       -DDOWNLOAD_PROTO_TFTP
#                       If defined, includes TFTP support (recommended).
#                       TFTP support is required if PXE support is selected.
#       -DDOWNLOAD_PROTO_NFS
#                       If defined, includes NFS support.
#       -DDEFAULT_PROTO_NFS
#                       If defined, makes NFS the default protocol instead
#                       of TFTP. Requires DOWNLOAD_PROTO_NFS.
#       -DDOWNLOAD_PROTO_SLAM
#                       If defined, includes Scalable Local Area Multicast
#                       support.
#       -DDOWNLOAD_PROTO_TFTM
#                       If defined, includes TFTP Multicast mode support.
#       -DDOWNLOAD_PROTO_HTTP
#                       If defined, includes HTTP support.
#
#       Console options:
#
#       -DCONSOLE_FIRMWARE
#                       Set for firmware/BIOS provided (default if nothing else is set).
#                       Normally this is shows up on your CRT.
#       -DCONSOLE_SERIAL
#                       Set for serial console.
#       -DCONSOLE_DUAL
#                       Both of the above
#       -DCONSOLE_DIRECT_VGA
#                       Set for direct VGA console (only for x86).
#       -DCOMCONSOLE
#                       Set port, e.g. 0x3F8.
#       -DCONSPEED
#                       Set speed, e.g. 57600.
#       -DCOMPARM
#                       Set Line Control Register value for data bits, stop
#                       bits and parity. See a National Semiconditor 8250/
#                       16450/16550 data sheet for bit meanings.
#                       If undefined, defaults to 0x03 = 8N1.
#       -DCOMPRESERVE
#                       Ignore COMSPEED and COMPARAM and instead preserve
#                       the com port parameters from the previous user
#                       of the com port.  Examples of previous user are a BIOS
#                       that implements console redirection, lilo and LinuxBIOS.
#                       This makes it trivial to keep the serial port
#                       speed setting in sync between multiple users.
#                       You set the speed in the first user and the
#                       rest follow along.
#
#       Interface export options:
#
#       -DPXE_EXPORT
#                       Export a PXE API interface.  This is work in
#                       progress.  Note that you won't be able to load
#                       PXE NBPs unless you also use -DPXE_IMAGE.
#       -DPXE_STRICT
#                       Strict(er) compliance with the PXE
#                       specification as published by Intel.  This may
#                       or may not be a good thing depending on your
#                       view of the spec...
#       -DPXE_DHCP_STRICT
#                       Strict compliance of the DHCP request packets
#                       with the PXE specification as published by
#                       Intel.  This may or may not be a good thing
#                       depending on your view of whether requesting
#                       vendor options which don't actually exist is
#                       pointless or not. You probably want this
#                       option if you intend to use Windows RIS or
#                       similar.
#
#       Obscure options you probably don't need to touch:
#
#       -DZPXE_SUFFIX_STRIP
#                       If the last 5 characters of the filename passed to Etherboot is
#                       ".zpxe" then strip it off. This is useful in cases where a DHCP server
#                       is not able to be configured to support conditionals. The way it works
#                       is that the DHCP server is configured with a filename like
#                       "foo.nbi.zpxe" so that when PXE asks for a filename it gets that, and
#                       loads Etherboot from that file. Etherboot then starts up and once
#                       again asks the DHCP server for a filename and once again gets
#                       foo.nbi.zpxe, but with this option turned on loads "foo.nbi" instead.
#                       This allows people to use Etherboot who might not otherwise be able to
#                       because their DHCP servers won't let them.
#
#       -DPOWERSAVE
#                       Halt the processor when waiting for keyboard input

# almost certainly means using '1' if the Client ID is an Ethernet MAC
# address and '0' otherwise. Set DHCP_CLIENT_ID_LEN to the length of

# NOT add 1 for a terminator and do NOT add an extra 1 for the

# This can be used for classification of clients, typically so that a

# string identifies a class of to which this client instance belongs
# which is useful in your network, such as a department ('FINANCE' or
# 'MARKETING') or hardware type ('THINCLIENT' or 'KIOSK').  Set
# DHCP_USER_CLASS_LEN to the length of DHCP_USER_CLASS in octets.
# This is NOT a null terminated C string, do NOT add 1 for a
