# IMPORTANT!

# The use of this file to set options that affect only single object
# files is deprecated, because changing anything in this file results
# in a complete rebuild, which is slow. All options are gradually
# being migrated to config.h, which does not suffer from this problem.
#
# Only options that affect the entire build (e.g. overriding the $(CC)
# Makefile variable) should be placed in here.

# Do not delete the tag OptionDescription and /OptionDescription
# It is used to automatically generate the documentation.
#
# @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.
# -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. Example:
# -DDEFAULT_BOOTFILE="tftp:///tftpboot/kernel"
# 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:
#
# -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
#
# 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:
#
# -DPOWERSAVE
# Halt the processor when waiting for keyboard input
# which saves power while waiting for user interaction.
# Good for compute clusters and VMware emulation.
# But may not work for all CPUs.

# CFLAGS+= -DREQUIRE_VCI_ETHERBOOT
# EXPERIMENTAL! Set DHCP_CLIENT_ID to create a Client Identifier (DHCP
# option 61, see RFC2132 section 9.14) when Etherboot sends the DHCP
# DISCOVER and REQUEST packets. This ID must UNIQUELY identify each
# client on your local network. Set DHCP_CLIENT_ID_TYPE to the
# appropriate hardware type as described in RFC2132 / RFC1700; this
# 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
# the Client ID in octets (this is not a null terminated C string, do
# NOT add 1 for a terminator and do NOT add an extra 1 for the
# hardware type octet). Note that to identify your client using the
# normal default MAC address of your NIC, you do NOT need to set this
# option, as the MAC address is automatically used in the
# hwtype/chaddr field; note also that this field only sets the DHCP
# option: it does NOT change the MAC address used by the client.

# EXPERIMENTAL! Set DHCP_USER_CLASS to create a User Class option (see
# RFC3004) when Etherboot sends the DHCP DISCOVER and REQUEST packets.
# This can be used for classification of clients, typically so that a
# DHCP server can send an appropriately tailored reply. Normally, 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
# terminator. RFC3004 advises how to lay out multiple User Class
# options by using an octet for the length of each string, as in this
# example. It is, of course, up to the server to parse this.

# on the NIC so that people after you won't get nasty surprises.
#
# -DCFG_3C90X_PRESERVE_XCVR - Reset the transceiver type to the value it
# had initially just before the loaded code is started.
# -DCFG_3C90X_XCVR - Hardcode the tranceiver type Etherboot uses.
# -DCFG_3C90X_BOOTROM_FIX - If you have a 3c905B with buggy ROM
# interface, setting this option might "fix" it. Use
