1.先在linux下建立一个空的硬盘镜像

dd if=/dev/zero f=medici_hd.img bs=512 count=524160

ps:柱面520，磁头16，每磁道扇区数63

2.安装SLS－linux

下载了1.0版本的，解压即可

在解压后的文件中建立一个新文件夹，命名linux0.12，把medici_hd.img放入，修改bochsrc.bxrc，内存大小改为16，注意把medici_hd.img挂接在系统第二个硬盘上

在ata0-master下加上一行

ata0-slave: type=disk, path=/usr/linux_0.12_labplatform/sls-1.0/linux0.12/medici_hd.img, cylinders=520, heads=16, spt=63

bochsrc.bxrc文件

# BOOT:
# This defines your boot drive.

# boot: cdrom
#=======================================================================
boot: a

#=======================================================================
# 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
# wavemode:
# 0=no data
# 1=output to device (system dependent. wave denotes the device driver)
# 2=VOC file output, incl. headers
# 3=output the raw wave stream to the file
# log: The file to write the sb16 emulator messages to.
# loglevel:
# 0=no log
# 1=only midi program and bank changes
# 2=severe errors
# 3=all errors
# 4=all errors plus all port accesses
# 5=all errors and port accesses plus a lot of extra info
# dmatimer:
# microseconds per second for a DMA cycle. Make it smaller to fix
# non-continous sound. 750000 is usually a good value. This needs a
# reasonably correct setting for IPS.
#
# For an example look at the next line:
#=======================================================================

#sb16: midimode=1, midi=/dev/midi00, wavemode=1, wave=/dev/dsp, loglevel=2, log=sb16.log, #dmatimer=600000

#=======================================================================
# VGA_UPDATE_INTERVAL:
# Video memory is scanned for updates and screen updated every so many
# virtual seconds. The default is 300000, about 3Hz. This is generally
# plenty. Keep in mind that you must tweak the 'ips:' directive
# to be as close to the number of emulated instructions-per-second
# your workstation can do, for this to be accurate.
#
# Examples:
# vga_update_interval: 250000
#=======================================================================
vga_update_interval: 300000

# using for Winstone '98 tests
#vga_update_interval: 100000

#=======================================================================
# KEYBOARD_SERIAL_DELAY:
# Approximate time in microseconds that it takes one character to
# be transfered from the keyboard to controller over the serial path.
# Examples:
# keyboard_serial_delay: 200
#=======================================================================
keyboard_serial_delay: 250

#=======================================================================
# KEYBOARD_PASTE_DELAY:
# Approximate time in microseconds between attempts to paste
# characters to the keyboard controller. This leaves time for the
# guest os to deal with the flow of characters. The ideal setting
# depends on how your operating system processes characters. The
# default of 100000 usec (.1 seconds) was chosen because it works
# consistently in Windows.
#
# If your OS is losing characters during a paste, increase the paste
# delay until it stops losing characters.
#
# Examples:
# keyboard_paste_delay: 100000
#=======================================================================
keyboard_paste_delay: 100000

#=======================================================================
# FLOPPY_COMMAND_DELAY:
# Time in microseconds to wait before completing some floppy commands
# such as read/write/seek/etc, which normally have a delay associated.
# I had this hardwired to 50,000 before.
#
# Examples:
# floppy_command_delay: 50000
#=======================================================================
#floppy_command_delay: 50000

#=======================================================================
# IPS:
# Emulated Instructions Per Second. This is the number of IPS that bochs
# is capable of running on your machine. Read the note in config.h
# on how to find this. Make sure to recompile after.
#
# IPS is used to calibrate many time-dependent events within the bochs
# simulation. For example, changing IPS affects the frequency of VGA
# updates, the duration of time before a key starts to autorepeat, and
# the measurement of BogoMips and other benchmarks.
#
# Examples:
# Machine Mips
# ________________________________________________________________
# 650Mhz Athlon K-7 with Linux 2.4.4/egcs-2.91.66 2 to 2.5 Mips
# 400Mhz Pentium II with Linux 2.0.36/egcs-1.0.3 1 to 1.8 Mips
# 166Mhz 64bit Sparc with Solaris 2.x approx 0.75 Mips
# 200Mhz Pentium with Linux 2.x approx 0.5 Mips
#
#=======================================================================
ips: 4000000

#=======================================================================
# mouse: Not used in any of the GUI specific modules, but the option
# bx_options.mouse_enabled is set to this value. The idea,
# is that the GUI code should not generate mouse events when
# not enabled. The hardware emualation itself is not disabled
# by this. This is to facilitate deterministic runs of bochs.
#
# Examples:
# mouse: enabled=1
# mouse: enabled=0
#
# I wouldn't recommend enabling the mouse by default, unless you have a
# really good reason to do so.
#=======================================================================
mouse: enabled=0

#=======================================================================
# private_colormap: Request that the GUI create and use it's own
# non-shared colormap. This colormap will be used
# when in the bochs window. If not enabled, a
# shared colormap scheme may be used. Not implemented
# on all GUI's.
#
# Examples:
# private_colormap: enabled=1
# private_colormap: enabled=0
#=======================================================================
private_colormap: enabled=0

#=======================================================================
# fullscreen: ONLY IMPLEMENTED ON AMIGA
# Request that Bochs occupy the entire screen instead of a
# window.
#
# Examples:
# fullscreen: enabled=0
# fullscreen: enabled=1
#=======================================================================
fullscreen: enabled=0
screenmode: name="sample"

#=======================================================================
# ne2k: NE2000 compatible ethernet adapter
#
# Examples:
# ne2k: ioaddr=IOADDR, irq=IRQ, mac=MACADDR, ethmod=MODULE, ethdev=DEVICE
#
# ioaddr, irc: You probably won't need to change ioaddr and irq, unless there
# are IRQ conflicts.
#
# mac: The MAC address MUST NOT match the address of any machine on the net.
# Also, the first byte must be an even number (bit 0 set means a multicast
# address), and you cannot use ff:ff:ff:ff:ff:ff because that's the broadcast
# address. For the ethertap module, you must use fe:fd:00:00:00:01. There may
# be other restrictions too. To be safe, just use the b0:c4... address.
#
# ethdev: The ethdev value is the name of the network interface on your host
# platform. On UNIX machines, you can get the name by running ifconfig. On
# Windows machines, you must run niclist to get the name of the ethdev.
# Niclist source code is in misc/niclist.c and it is included in Windows
# binary releases.
#=======================================================================
# ne2k: ioaddr=0x280, irq=9, mac=b0:c4:20:00:00:00, ethmod=fbsd, ethdev=xl0
# ne2k: ioaddr=0x280, irq=9, mac=b0:c4:20:00:00:00, ethmod=linux, ethdev=eth0

# KEYBOARD_MAPPING:
# This enables a remap of a physical localized keyboard to a

#=======================================================================
# KEYBOARD_TYPE:
# Type of keyboard return by a "identify keyboard" command to the
# keyboard controler. It must be one of "xt", "at" or "mf".
# Defaults to "mf". It should be ok for almost everybody. A known

常见问题小结

1.Message: ROM: System BIOS must end at 0xfffff

问题原因：
在2.3.5以前的bochs使用的BIOS-bochs-latest是64k的，那个时候需要加上
romimage: file=BIOS-bochs-latest,address=0xf0000
在2.3.5中的BIOS-bochs-latest更新了，变成了128k的，这个时候配置需要改为
romimage: file=$BXSHARE/BIOS-bochs-latest

解决方法：
去掉配置文件中的address那个

2. directive 'floppy_command_delay' not understood

解决方法：

注掉floppy_command_delay: 50000
