Boot Cheat Codes
Boot codes or Cheat codes are parameters you can add during boot to syslinux to alter the behavior of Backtrack. Boot codes must start with "bt" (e.g. bt nodhcp) at the boot prompt. Below you can find some of them.
bt acpi=off
skip acpi hardware detection in the case of hangups. Only way I could get my laptop (HP zv-6000 also worked on my HP pavilion Home entertainment pc) to boot without black screen (Also needed for Dell Inspiron B130 Laptop).
dbt
dbt (instead of bt) Dual processor/core support. If you get SQUASHFS errors, you can't use dual core support.
bt irqpoll
use "bt irqpoll" if shows no PCI interrupts & disabling cardbus in dmesg (e.g. using ubiquiti SRC card)
bt noagp
skip agp hardware detection in the case of hangups.
bt nodhcp
This option prevents your network adapters from using DHCP[1] during the boot process.
bt nohd
When you plan to do forensic work, you should boot using "bt nohd" to prevent automounting hard disks.
bt nopcmcia
skip pcmcia hardware detection in the case of hangups.
bt nosound
Start with sound level 0%
bt changes=/dev/device
All changes you made in BT are kept in memory until you reboot. But with this boot parameter, you tell BT to use a different device than memory for storing changes. You can, for example, format your disk partition /dev/hda1 with some Linux 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.
