Message-ID: <758@csm9a.UUCP>

Organization: Colorado School of Mines
Lines: 218

This shar file will create 3 cdiff's to patch the Minix 1.3 kernel to
work with a Tandy 1000 or 1000A... they may or may not work with the
new SX models.
These diffs are derived from a very early MINIX fix posted by John Clark
Cdiff's will be produced for const.h main.c and floppy.c
A makefile (tn_makefile) will also be generated

# ------- cut here and pass to sh -------
# Tandy 1000 and 1000A cdiffs for Minix 1.3

X# The kernel dir contains xt_wini.c and at_wini.c.  Before running make
X# you must copy one of these to wini.c, depending on which controller you
X# have.  If you do not have a hard disk, you MUST choose one of them at random.
X# On a PC, cpp and cem are in /lib and will be removed to make space while
X# linking the kernel.  On an AT, they are in /usr/lib are are not removed.
X# This is because they have to be in /lib on a PC; the diskette is too small
X# for them to be in /usr/lib.  You can change this by editing commands/cc.c.
X#
X# Normally, MINIX scrolls the screen using the 6845's registers.  However,
X# on some EGA cards (those that are not IBM compatible), the 6845 is not
X# properly emulated.  On these machines, it is necessary to scroll in
X# software by copying. This is much slower, but it works. The CFLAGS flags are:
X#
X#  -Di8088	- required on an 8088/80286/80386 CPU; forbidden on a 68000
X#  -F		- run cpp and cem sequentially (used when memory is tight)
X#  -T.		- put temporaries in working directory (when RAM disk is small)
X#
X# In the standard distribution, the following defaults are set
X#  PC:		CFLAGS = -Di8088 -F -T.
X#  Tandy:       CFLAGS = -Di8088 -DT1K -F -T.
X#  AT:		CFLAGS = -Di8088 -F 
X#
XCFLAGS= -Di8088 -DT1K -F -T.
