Hardware options (Page 1): acpi=on This loads support for ACPI and also causes the acpid daemon to be started by the CD on boot. This is only needed if your system requires ACPI to function properly. This is not required for Hyperthreading support. acpi=off Completely disables ACPI. This is useful on some older systems and is also a requirement for using APM. This will disable any Hyperthreading support of your processor. console=X This sets up serial console access for the CD. The first option is the device, usually ttyS0 on x86, followed by any connection options, which are comma separated. The default options are 9600,8,n,1. dmraid=X This allows for passing options to the device-mapper RAID subsystem. Options should be encapsulated in quotes. doapm This loads APM driver support. This requires you to also use acpi=off. dopcmcia This loads support for PCMCIA and Cardbus hardware and also causes the pcmcia cardmgr to be started by the CD on boot. This is only required when booting from PCMCIA/Cardbus devices. doscsi This loads support for most SCSI controllers. This is also a requirement for booting most USB devices, as they use the SCSI subsystem of the kernel.
