Boot parameters
This page contains various boot parameters that ArchPwn accepts. You could make this changes permanently by editing directly isolinux.cfg in your USB stick. If you have a readonly support press TAB at the boot menu and append this parameters to the current line.
Skip ACPI hardware detection
If you're experiencing hang-ups while booting, you can skip ACPI hardware detection by appending to the boot-line:
acpi=off
Prevent PCI interuptions
Append to the boot-line:
irqpoll
To have no PCI interruptions and to disable the cardbus in dmesg (e.g. using ubiquiti SRC card).
Altering target device for saving changes
All changes that are made while in ArchPwn are kept in the RAM, by using the boot parameter:
changes=/dev/device
You can tell ArchPwn to use a different device other than memory for storing changes. For example, you can reformat your disk partition /dev/hda1 to a Linux-compatible filesystem (eg. ext2) and then use changes=/dev/hda1 to store all changes to that disk. This way you won't loose your changes after reboot.
