# Makefile for NETBOOT
#
# Basic Options:
#	-DSECURE_BOOT	- Disable 'boot>' prompt completely
#	-DASK_BOOT	- Ask "Boot from Network (Y/N) ?" at startup
#	-DROMSIZE	- Size of EPROM - Must be set (even for .COM files)
#	-DRELOC		- Relocation address (usually 0x90000)
#
# NS8390 Options:
#	-DINCLUDE_WD	- Include Western Digital/SMC support
#	-DINCLUDE_NE	- Include NE1000/NE2000 support
#	-DINCLUDE_3COM  - Include 3c503 support
#       -D_3COM_USE_AUI - Disable transceiver on 3c503 by default
#	-DNE_BASE	- Base I/O address for NE1000/NE2000
#       -D_3COM_BASE    - Base I/O address for 3c503
#	-DWD_DEFAULT_MEM- Default memory location for WD/SMC cards
# XXX nothing depends on this Makefile so you must run `make clean' after
# changing an option.
