# VGA_UPDATE_INTERVAL:

|
# Video memory is scanned for updates and screen updated every so many

|
# 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

# KEYBOARD_SERIAL_DELAY:

# Approximate time in microseconds that it takes one character to

|
# keyboard_serial_delay: 200

# Time in microseconds to wait before completing some floppy commands

# 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

# MAX_IPS and SYSTEM_CLOCK_SYNC
|
|
# These two options are experimental, and may not even be implemented
|
|
# yet. If MAX_IPS is set to a value other than 0, Bochs will try to
|
|
# slow down the simulation until the average instructions per unit time
|
|
# reaches MAX_IPS. This can be used to prevent Bochs from speeding through
|
|
# wait intervals, which has caused problems with key autorepeats and
|
|
# other time sensitive tasks. SYSTEM_CLOCK_SYNC prohibits the Bochs
|
|
# simulation from running (very much) faster than the system clock, also
|
|
# by inserting delays occasionally. Some examples of how ips,max_ips,
|
|
# and system_clock sync interact:
|
|
# 1. ips=500000, max_ips=0, system_clock_sync disabled
|
|
# Bochs runs as fast as possible. Timer interrupts are scheduled
|
|
# as if it was running at 500000 instructions per second. This is
|
|
# the old behavior, and it's still the default.
|
|
# 2. ips=500000, max_ips=700000, system_clock_sync enabled.
|
|
# Bochs will not run faster than system time, and if it gets behind
|
|
# it will run at a maximum of 40% faster than real time until it
|
|
# catches up.
|
|
# 3. ips=500000, max_ips=500000, system_clock_sync disabled
|
|
# If Bochs gets behind, it will stay behind forever
|
|
# instead of running faster to catch up with the system clock.

# 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.

#

# mouse: enabled=1
