 - mv gmp-4.3.2 gcc-4.7.0/gmp
 - mv mpfr-2.4.2 gcc-4.7.0/mpfr
 - mv mpc-0.8.1 gcc-4.7.0/mpc
 - Build binutils
 - cd build_binutils
 - ../binutils-2.22/configure --target=$TARGET --prefix=$PREFIX --disable-nls
 - make all
 - make install
 - cd ..
 - Build gcc
 - cd build_gcc
 - ../gcc-4.7.0/configure --target=$TARGET --prefix=$PREFIX --disable-nls --enable-languages=c --without-headers
 - make all-gcc
 - make install-gcc
- Install QEMU:
 - Precompiled Windows binaries are located at http://lassauge.free.fr/qemu/
 - Install http://lassauge.free.fr/qemu/release/Qemu-1.0.1-windows.zip
 - Copy bios.bin and vgabios-cirrus.bin from the Bios folder to QEMU's
 root directory.
- Install the TAP driver:
 - OpenVPN installers are located at http://openvpn.net/index.php/download.html
 - Install http://swupdate.openvpn.org/community/releases/openvpn-2.2.2-install.exe
 - Install only the "TAP Virtual Ethernet Adapter" component.
 - Modify the Network Connections:
 - Rename the TAP interface from "Local Area Connection (n)" to "tap"
 - Bridge the TAP interface with your active Local Area Connection.
- Update PATH:
 - Add QEMU and /usr/local/cross/bin to the PATH variable in .bash_profile
-------------------------------------------------------------------------------
Configuration:
- g_localTimeZone in time.c
-------------------------------------------------------------------------------
What to expect:
- Type 'help' to see available commands. Some examples:
 - 'http' fetches web pages
 - 'gfx' switches into graphics mode
 - 'host' performs a DNS lookup on a hostname
 - 'ping' sends an ICMP echo request to an IP address
 - 'lsroute' prints the routing table
 - 'datetime' prints the current time
 - 'synctime' sends an NTP request and updates the CMOS
- tools/os_helper.exe provides services to improve OS development. Currently
 this is used for remote logging via UDP.
-------------------------------------------------------------------------------
Emulator steps:
 $ make
 $ qemu.bat
-------------------------------------------------------------------------------
Hardware steps:
 Format a FAT16 drive, update the boot sector and copy the loader and kernel
 binaries.
 $ make
 $ tools/set_boot.exe //./<drive letter>: boot/boot.bin
 $ cp boot/loader.bin <drive letter>:/
 $ cp kernel/kernel.bin <drive letter>:/
 Boot!
