# Makefile for MemTest-86
#
# Author: Chris Brady
# Created: January 1, 1996
#
# Enhancements - V1.2: May 28, 1996 by Loic Prylli
#
#
# Path for the floppy disk device
#
FDISK=/dev/fd0
#
# Comment out the following to disable testing with cache off
#
CACHE=-DCACHE
#
# Comment out the following to disable testing with long refresh timing
#
REFRESH=-DREFRESH
#
# gcc compiler options, these settings should suffice
#
CCFLAGS=-Wall -m486 -O2
# WARNING - Read the following carefully if you modify the code in any way!
#
# TXT_ADR sets the origin for the text segment. Since the code is
# relocated there are two code segments. The first must match TESTADR in
# mtest.h. The second REL_TXT_ADR must be set to (TESTADR+MAIN_SZ+RELOBASE)
# in mtest.h.
#
# DAT_ADR sets the origin for the data segment. This is is set by hand and
# will need to be adjusted if the code grows much. The current settings
# leave only a small amount of room for growth. Look at the loader map to
# check this address. The total size of the text and data segments must
# be less than MAINSZ in mtest.h. REL_DAT_ADR should be set to
# REL_TXT_ADR + (DAT_ADR - TXT_ADR)
#
TXT_ADR=0x1000
DAT_ADR=0x2600
REL_TXT_ADR=0x102800
REL_DAT_ADR=0x103e00
