   2 # Makefile for Etherboot
   3 #
   4 # Most of the time you should edit Config
   5 #
   6 # Common options:
   7 #       VERSION=v       - Set the version string
   8 #
   9 # NS8390 options:
  10 #       -DINCLUDE_NE    - Include NE1000/NE2000 support
  11 #       -DNE_SCAN=list  - Probe for NE base address using list of
  12 #                         comma separated hex addresses
  13 #       -DINCLUDE_3C503 - Include 3c503 support
  14 #         -DT503_SHMEM  - Use 3c503 shared memory mode (off by default)
  15 #       -DINCLUDE_WD    - Include Western Digital/SMC support
  16 #       -DWD_DEFAULT_MEM- Default memory location for WD/SMC cards
  17 #       -DCOMPEX_RL2000_FIX
  18 #
  19 #       If you have a Compex RL2000 PCI 32-bit (11F6:1401),
  20 #       and the bootrom hangs in "Probing...[NE*000/PCI]",
  21 #       try enabling this fix... it worked for me :).
  22 #       In the first packet write somehow it somehow doesn't
  23 #       get back the expected data so it is stuck in a loop.
  24 #       I didn't bother to investigate what or why because it works
  25 #       when I interrupt the loop if it takes more then COMPEX_RL2000_TRIES.
  26 #       The code will notify if it does a abort.

  28 #
  29 # 3C509 option:
  30 #       -DINCLUDE_3C509 - Include 3c509 support
  31 #
  32 # 3C90X options:
  33 #       -DINCLUDE_3C90X - Include 3c90x support
  34 #       -DCFG_3C90X_PRESERVE_XCVR - Reset the transceiver type to the value it
  35 #                         had initially just before the loaded code is started.
  36 #       -DCFG_3C90X_XCVR - Hardcode the tranceiver type Etherboot uses.
  37 #       -DCFG_3C90X_BOOTROM_FIX - If you have a 3c905B with buggy ROM
  38 #                         interface, setting this option might "fix" it.  Use
  39 #                         with caution and read the docs in 3c90x.txt!
  40 #
  41 #       See the documentation file 3c90x.txt for more details.
  42 #
  43 # CS89X0 (optional) options:
  44 #       -DINCLUDE_CS89X0- Include CS89x0 support
  45 #       -DCS_SCAN=list  - Probe for CS89x0 base address using list of
  46 #                         comma separated hex addresses; increasing the
  47 #                         address by one (0x300 -> 0x301) will force a
  48 #                         more aggressive probing algorithm. This might
  49 #                         be neccessary after a soft-reset of the NIC.
  50 #
  51 # LANCE options:

  53 #       -DINCLUDE_NI6510- Include NI6510 support

  61 #       -DINCLUDE_EXOS205-Include EXOS205 support
  62 #
  63 # SMC9000 options:
  64 #       -DINCLUDE_SMC9000   - Include SMC9000 driver
  65 #       -DSMC9000_SCAN=list - List of I/O addresses to probe
  66 #
  67 # TIARA (Fujitsu Etherstar) options:

  75 #       -DUSE_INTERNAL_BUFFER - receuve and transmit buffers within program
  76 #               space, not below 0x10000, in case that region is used
  77 #
  78 # RTL8139 options:
  79 #       -DINCLUDE_RTL8139 - Include RTL8139 support
  80 #       -DUSE_INTERNAL_BUFFER - 8 kB receive buffer within program space,
