# Debug - enables the debugging port and consists of two comma-separated parameters: com port and baud rate;
# it is also possible to specify custom port address with: COM0:[address],[baud_rate]
# Default - specifies which operating system listen in config file will be started if no choice is made
# Theme - allows to set a custom theme to personalize XTLDR's look'n'feel
# Timeout - sets the countdown timer (in seconds) before the default OS get started automatically
# Tune - plays a tune on the pcspeaker right before the XTLDR loads

Comments must start\n# with a semicolon (;) or a hash character (#) and run to the end of the line.\n#\n# Basic section is [XTLDR] which contains a bootloader specific options:\n# Debug - enables the debugging port and consists of two comma-separated parameters: com port and baud rate;\n# it is also possible to specify custom port address with: COM0:[address],[baud_rate]\n# Default - specifies which operating system listen in config file will be started if no choice is made\n# Theme - allows to set a custom theme to personalize XTLDR's look'n'feel\n# Timeout - sets the countdown timer (in seconds) before the default OS get started automatically\n# Tune - plays a tune on the pcspeaker right before the XTLDR loads\n#\n# Another type of section is [OS-Section] which adds a new position (operating system) to the boot menu. Each type\n# of the operating system provides a set of available parameters. If unsupported option is added, it is being ignored\n# by the XT Boot Loader. The available options are:\n# SystemName - sets a long operating system name that will be shown on the boot menu\n# SystemType - specifies an OS type from a predefined list of supported boot protocols\n# SystemPath - the ARC path, eg. multi(0)disk(0)rdisk(0)partition(1)\n# KernelFile - sets kernel filename with optional path relative to SystemPath\n# InitrdFile - sets initramfs image filename with optional path relative to SystemPath\n# HalFile - sets HAL filename with optional path relative to SystemPath\n# Parameters - specifies extra boot options for the kernel\n[XTLDR]Tune=400 880 2 988 2 783 2 392 2 587 3Debug=COM1,115200Timeout=30Theme=FancyDefault=ExectOS[ExectOS]SystemName=\"ExectOS Operating System\"SystemType=XTOSSystemPath=multi(0)disk(0)rdisk(0)partition(1)/ExectOSKernelFile=xtoskrnl.exeParameters=DEBUG DEBUGPORT=COM1,115200[Windows]SystemName=\"Microsoft Windows 2000\"SystemType=NT50SystemPath=multi(0)disk(0)rdisk(0)partition(2)/WindowsKernelFile=ntoskrnl.exeHalFile=hal.dllParameters=/NOGUIBOOT /MININT[Linux]SystemName=\"GNU/Linux\"SystemType=LINUXSystemPath=multi(0)disk(0)rdisk(0)partition(3)/bootKernelFile=vmlinuzInitrdFile=initramfs.cpio.gzParameters=root=/dev/xvda3 rootfstype=ext4", &ConfigSections);
