A known -# exception is french macs, that do have a "at"-like keyboard. -# -# SERIAL_DELAY: -# Approximate time in microseconds that it takes one character to -# be transferred from the keyboard to controller over the serial path. -# -# 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. -# -# KEYMAP: -# This enables a remap of a physical localized keyboard to a -# virtualized us keyboard, as the PC architecture expects. -# -# USER_SHORTCUT: -# This defines the keyboard shortcut to be sent when you press the "user" -# button in the headerbar. The shortcut string is a combination of maximum -# 3 key names (listed below) separated with a '-' character. -# Valid key names: -# "alt", "bksl", "bksp", "ctrl", "del", "down", "end", "enter", "esc", -# "f1", ...

The other choices are 'imps2' (wheel mouse -# on PS/2), 'serial', 'serial_wheel', 'serial_msys' (one com port requires -# setting 'mode=mouse') 'inport' and 'bus' (if present). To connect a mouse -# to a USB port, see the 'usb_uhci', 'usb_ohci', 'usb_ehci' or 'usb_xhci' -# options (requires PCI and USB support). -# -# ENABLED: -# The Bochs gui creates mouse "events" unless the 'enabled' option is -# set to 0.

You can also toggle the mouse -# usage at runtime (RFB, SDL, Win32, wxWidgets and X11 - see below). -# -# TOGGLE: -# The default method to toggle the mouse capture at runtime is to press the -# CTRL key and the middle mouse button ('ctrl+mbutton').

Up to 5 slots -# are available. For combined PCI/ISA devices assigning to slot is mandatory -# if the PCI model should be emulated (cirrus, ne2k and pcivga). Setting up -# slot for PCI-only devices is also supported, but they are auto-assigned if -# not specified (e1000, es1370, pcidev, pcipnic, usb_ehci, usb_ohci, usb_xhci, -# voodoo). All device models except the network devices ne2k and e1000 can be -# used only once in the slot configuration. In case of the i440BX chipset, the -# slot #5 is the AGP slot. Currently only the 'voodoo' device can be assigned -# to AGP. -# -# ADVOPTS: -# With the advanced PCI options it is possible to control the behaviour of the -# PCI chipset. These options can be specified as comma-separated values. -# By default the "Bochs i440FX" chipset enables the ACPI and HPET devices, but -# original i440FX doesn't support them. The options 'noacpi' and 'nohpet' make -# it possible to disable them. The option 'noagp' disables the incomplete AGP -# subsystem of the i440BX chipset. -# -# Example: -# pci: enabled=1, chipset=i440fx, slot1=pcivga, slot2=ne2k, advopts=noacpi -#======================================================================= -pci: enabled=1, chipset=i440fx - -#======================================================================= -# CLOCK: -# This defines the parameters of the clock inside Bochs: -# -# SYNC: -# This defines the method how to synchronize the Bochs internal time -# with realtime. With the value 'none' the Bochs time relies on the IPS -# value and no host time synchronization is used. The 'slowdown' method -# sacrifices performance to preserve reproducibility while allowing host -# time correlation. The 'realtime' method sacrifices reproducibility to -# preserve performance and host-time correlation. -# It is possible to enable both synchronization methods. -# -# RTC_SYNC: -# If this option is enabled together with the realtime synchronization, -# the RTC runs at realtime speed. This feature is disabled by default. -# -# TIME0: -# Specifies the start (boot) time of the virtual machine.
