boot.sh

#!/bin/bash
#
# Usage: ./boot.sh [config] [pc.js arguments...]
#
# Builds and boots BASIC-DOS with one of the configurations in software/src/configs/console, after
# tools/tests/prep.sh copies the test binaries into it.  Any additional arguments are passed to pc.js
# (eg, --halt, or a list of commands to run, such as "VER;MEM", which pc.js adds to CONFIG.SYS's SHELL
# line, or if they don't fit, to AUTOEXEC.BAT).  Changes to the boot disk are NOT saved back to the
# config folder (--nosync).
#
# The machine is a 2Mb IBM PC AT (ibm5170 with --ram=2M, which pc.js splits into 640K of conventional memory and 1408K
# of extended memory, unless another --ram is given), whose real-time clock sets the date and time.  Each
# configuration's CONFIG.SYS has a "CPU=8088" line, so CPU$ acts as it does on an 8088 and BASIC-DOS runs in real
# mode (tools/tests/mmutest.sh's pm and r3 machines and tools/tests/pmboot.sh boot without it).
#
#   fpe     floppy, console on COM1, no FPU (the default)
#   fpu     floppy, console on COM1, with an 80287
#   hd      10Mb hard disk (C:), console on COM1 (see tools/tests/testhd.sh for booting BASIC-DOS from
#           a diskette with an MS-DOS-formatted hard disk instead)
#   bios    floppy, VKD$ driver (see configs/console/bios/CONFIG.SYS) on a CGA
#   cga     alias for bios
