# You many now use double quotes around pathnames, in case
# your pathname includes spaces.

#=======================================================================
# ROMIMAGE:
# You now need to load a ROM BIOS into F0000-FFFFF.  I've wiped
# out most of the BIOS hooks, and replace them with real BIOS
# support.  Normally, you can use a precompiled BIOS in the bios/
# directory, named BIOS-bochs-yymmdd.  Use the latest one in there.
#=======================================================================
#romimage: bios/BIOS-bochs-970717a
romimage: file=$BXSHARE\BIOS-bochs-latest, address=0xf0000
#romimage: file=bios/BIOS-bochs-2-processors, address=0xf0000
#romimage: file=bios/BIOS-bochs-4-processors, address=0xf0000
#romimage: file=bios/rombios.bin, address=0xf0000

#=======================================================================
# MEGS
# set this to the default number of Megabytes of memory you want
# to emulate.  You may also pass the '-megs xyz' option to bochs
#
# The default is 32MB, most OS's won't need more than that.

# FLOPPYA:
# Point this to pathname of floppy image file or device
# This should be of a bootable floppy(image/device) if you're
# booting from 'a'.
#
# You can set the initial status of the media to 'ejected' or 'inserted'.
#   floppya: 2_88=path, status=ejected             (2.88M 3.5" floppy)
#   floppya: 1_44=path, status=inserted            (1.44M 3.5" floppy)
#   floppya: 1_2=path, status=ejected              (1.2M  5.25" floppy)
#   floppya: 720k=path, status=inserted            (720K  3.5" floppy)
#
# The path should be the name of a disk image file.  On unix, you can use
# a raw device name such as /dev/fd0 on Linux.  On WinNT and Win2k, use
# drive letters such as a: or b: as the path.  Raw floppy access is not
# supported on Windows 95 and 98.

#floppya: 1_2=../1_2, status=inserted
#floppya: 1_44=a:, status=inserted             # for win32

# DISKC: file=, cyl=, heads=, spt=
# Point this at a 10M, 20M, or 30M hard disk image file.  To create 
# a hard disk image, try running bximage.  It will help you choose the
# size and then suggest a diskc line that works with it.
#
# In UNIX it may be possible to use a raw device as a Bochs hard disk, 
# but WE DON'T RECOMMEND IT.  In Windows there is no easy way.
#
# Examples:
#   diskc: file=10M.sample, cyl=306, heads=4, spt=17
#   diskc: file=20M.sample, cyl=615, heads=4, spt=17
#   diskc: file=30M.sample, cyl=615, heads=6, spt=17
#   diskc: file=46M.sample, cyl=940, heads=6, spt=17
#   diskc: file=62M.sample, cyl=940, heads=8, spt=17
#   diskc: file=112M.sample, cyl=900, heads=15, spt=17
#   diskc: file=483M.sample, cyl=1024, heads=15, spt=63

# CDROM
#
# cdromd: dev=/dev/cdrom, status=inserted
# cdromd: dev=/dev/cdrom, status=ejected
# cdromd: dev=e:, status=ejected
#
# In windows, the drive letter + colon notation should be used.  Depending
# on versions of windows and drivers, you may only be able to access the
# "first" cdrom in the system.
#
# NOTE: diskd and cdromd must not be used together!
#=======================================================================
#cdromd: dev=D:, status=inserted             # for win32
#cdromd: dev=/dev/cdrom, status=inserted

# NEWHARDDRIVESUPPORT: enabled=[0|1]
# As of cvs version on 5/17/2001, newharddrivesupport is on by default.
#=======================================================================
#newharddrivesupport: enabled=1

#=======================================================================
# BOOT:
# This defines your boot drive.  
# You can either boot from 'a', 'c' or 'cdrom'
# Examples:
#   boot: c
#   boot: a
#   boot: cdrom
#=======================================================================
boot: a
#boot: c

#=======================================================================
# LOG:
# Give the path of the log file you'd like Bochs debug and misc. verbage
# to be written to.  If you really don't want it, make it /dev/null. :^(
#
# Examples:
#   log: ./bochs.out
#   log: /dev/tty
#=======================================================================
#log: /dev/null
log: bochsout.txt

#=======================================================================
# LOG CONTROLS
#
# Bochs now has four severity levels for event logging.
#   panic: cannot proceed.  If you choose to continue after a panic, 
#          don't be surprised if you get strange behavior or crashes.
#   error: something went wrong, but it is probably safe to continue the
#          simulation.
#   info: interesting or useful messages.
#   debug: messages useful only when debugging the code.  This may
#          spit out thousands per second.
#
# For events of each level, you can choose to crash, report, or ignore.
# TODO: allow choice based on the facility: e.g. crash on panics from
#       everything except the cdrom, and only report those.
#
# If you are experiencing many panics, it can be helpful to change
# the panic action to report instead of fatal.  However, be aware
# that anything executed after a panic is uncharted territory and can 
# cause bochs to become unstable.  The panic is a "graceful exit," so
# if you disable it you may get a spectacular disaster instead.
#=======================================================================
#panic: action=ask
#error: action=report
#info: action=report
#debug: action=ignore

#=======================================================================
# com1:
# Specify the device to use as com1.  This can be a real serial line, or
# a pty.  To use a pty (under X/Unix), create two windows (xterms,
# usually).  One of them will run bochs, and the other will act as com1.
# Find out the tty the com1 window using the `tty' command, and use that
# as the `dev' parameter.  Then do `sleep 1000000' in the com1 window to
# keep the shell from messing with things, and run bochs in the other
# window.  Serial I/O to com1 (port 0x3f8) will all go to the other
# window.
#=======================================================================
#com1: dev=/dev/ttyp9


#=======================================================================
# PARPORT1:
# This defines a parallel (printer) port.  When turned on, the emulated
# printer port sends characters printed by the guest OS into an output file.
#
# Examples:
#   parport1: enable=1, file="parport.out"
#   parport1: enable=0
#=======================================================================
parport1: enable=0

#=======================================================================
# SB16:
# This defines the SB16 sound emulation. It can have several of the
# following properties.
# All properties are in the format sb16: property=value
# midi: The filename is where the midi data is sent. This can be a
#       device or just a file if you want to record the midi data.
# midimode:
#      0=no data
#      1=output to device (system dependent. midi denotes the device driver)
#      2=SMF file output, including headers
#      3=output the midi data stream to the file (no midi headers and no
#        delta times, just command and data bytes)
# wave: This is the device/file where wave output is stored
