# Makefile for Etherboot
#
# Most of the time you should edit Config
#
# Common options:
#	VERSION=v	- Set the version string
#
# NS8390 options:
#	-DINCLUDE_NE	- Include NE1000/NE2000 support
#	-DNE_SCAN=list	- Probe for NE base address using list of
#			  comma separated hex addresses
#	-DINCLUDE_3C503 - Include 3c503 support
#	  -DT503_SHMEM	- Use 3c503 shared memory mode (off by default)
#	-DINCLUDE_WD	- Include Western Digital/SMC support
#	-DWD_DEFAULT_MEM- Default memory location for WD/SMC cards
#	-DCOMPEX_RL2000_FIX
#
#	If you have a Compex RL2000 PCI 32-bit (11F6:1401),
#	and the bootrom hangs in "Probing...[NE*000/PCI]",
#	try enabling this fix... it worked for me :).
#	In the first packet write somehow it somehow doesn't
#	get back the expected data so it is stuck in a loop.
#	I didn't bother to investigate what or why because it works
#	when I interrupt the loop if it takes more then COMPEX_RL2000_TRIES.
#	The code will notify if it does a abort.
#	SomniOne - [e-mail]
#
# 3C509 option:
#	-DINCLUDE_3C509	- Include 3c509 support
#
# 3C90X options:
#	-DINCLUDE_3C90X	- Include 3c90x support
#	-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
#			  with caution and read the docs in 3c90x.txt!
#
#	See the documentation file 3c90x.txt for more details.
#
# CS89X0 (optional) options:
#	-DINCLUDE_CS89X0- Include CS89x0 support
#	-DCS_SCAN=list	- Probe for CS89x0 base address using list of
#			  comma separated hex addresses; increasing the
#			  address by one (0x300 -> 0x301) will force a
#			  more aggressive probing algorithm. This might
#			  be neccessary after a soft-reset of the NIC.
#
# LANCE options:
#	-DINCLUDE_NE2100- Include NE2100 support
#	-DINCLUDE_NI6510- Include NI6510 support
#
# SK_G16 options:
#	-DINCLUDE_SK_G16- Include SK_G16 support
#
# I82586 options:
#	-DINCLUDE_3C507	- Include 3c507 support
#	-DINCLUDE_NI5210- Include NI5210 support
#	-DINCLUDE_EXOS205-Include EXOS205 support
#
# SMC9000 options:
#       -DINCLUDE_SMC9000   - Include SMC9000 driver
#       -DSMC9000_SCAN=list - List of I/O addresses to probe
#
# TIARA (Fujitsu Etherstar) options:
#	-DINCLUDE_TIARA	- Include Tiara support
#
# NI5010 options:
#	-DINCLUDE_NI5010 - Include NI5010 support
#
# TULIP options:
#	-DINCLUDE_TULIP	- Include Tulip support
#	-DUSE_INTERNAL_BUFFER - receuve and transmit buffers within program
#		space, not below 0x10000, in case that region is used
#
# RTL8139 options:
#	-DINCLUDE_RTL8139 - Include RTL8139 support
#	-DUSE_INTERNAL_BUFFER - 8 kB receive buffer within program space,
#		not at 0x10000 - 8kB, in case that region is used
#
