- 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!
