![]() Noudev - This disables udev support on 2.6 kernels. This is not safe to use with lvm2.ĭolvm2 - This enables support for Linux's Logical Volume Management. Since devfs is the only option with a 2.4 kernel, this option has no effect if booting a 2.4 kernel.ĭoevms2 - This enables support for IBM's pluggable EVMS, or Enterprise Volume Management System. You will also need to use noudev for this to take effect. This is useful for debugging USB issues.ĭodevfs - This enables the deprecated device filesystem on 2.6 systems. Nousb - This disables the autoloading of USB modules. This is useful for systems where sound support causes problems. Nosound - This disables sound support and volume setting. This is useful for debugging SMP-related issues with certain drivers and motherboards. Nosmp - This disables SMP, or Symmetric Multiprocessing, on SMP-enabled kernels. This is useful if your system is having problems with the SATA subsystem. Nosata - This disables the loading of Serial ATA modules. Nolapic - This disables the local APIC on Uniprocessor kernels. Nokeymap - This disables the keymap selection used to select non-US keyboard layouts. This is useful for doing debugging of a failing CD or driver. Nohotplug - This disables the loading of the hotplug and coldplug init scripts at boot. Nogpm - This diables gpm console mouse support. This should only be necessary if your Firewire hardware is causing a problem with booting the CD. Nofirewire - This disables the loading of Firewire modules. Nodmraid - Disables support for device-mapper RAID, such as that used for on-board IDE/SATA RAID controllers. This is useful on networks with only static addresses. Nodhcp - This disables DHCP probing on detected network cards. Nodetect - This disables all of the autodetection done by the CD, including device autodetection and DHCP probing. It has been known to cause some problems on older hardware. Noapic - This disables the Advanced Programmable Interrupt Controller that is present on newer motherboards. This also disables the default hdparm settings from being executed. If your system is having trouble reading from your IDE CDROM, try this option. Ide=nodma - This forces the disabling of DMA in the kernel and is required by some IDE chipsets and also by some CDROM drives. Replace hda with the device that is requiring this option. This option is only used on machines with an older BIOS. Hda=stroke - This allows you to partition the whole hard disk even when your BIOS is unable to handle large disks. This is also a requirement for booting most USB devices, as they use the SCSI subsystem of the kernel. This is only required when booting from a PCMCIA/Cardbus device.ĭoscsi - This loads support for most SCSI controllers. ![]() This requires you to also use acpi=off.ĭobladecenter - This adds some extra pauses into the boot process for the slow USB CDROM of the IBM BladeCenter.ĭopcmcia - This loads support for PCMCIA and Cardbus hardware and also causes the pcmcia cardmgr to be started by the CD on boot. Options should be encapsulated in quotes.ĭoapm - This loads APM driver support. The default options are 9600,8,n,1.ĭmraid=X - This allows for passing options to the device-mapper RAID subsystem. The first option is the device, usually ttyS0 on x86, followed by any connection options, which are comma separated. This will disable any Hyperthreading support of your processor.Ĭonsole=X - This sets up serial console access for the CD. This is useful on some older systems, and is also a requirement for using APM. This is not required for Hyperthreading support.Īcpi=off - Completely disables ACPI. This is only needed if your system requires ACPI to function properly. Easily remove malicious objects from your computer without the risk ofĪcpi=on - This loads support for ACPI and also causes the acpid daemon to be started by the CD on boot. For example, "doscsi" enables SCSI support in the initial ramdisk boot, while "noscsi" disables it. This lists the Gentoo-specific options, along with a few options that are built-in to the kernel, but that have been proven very useful to our users.Īlso, all options that start with "do" have a "no" inverse, that does the opposite. Boot from the Kaspersky Rescue Disk to scan and remove threats from an infected computer without the risk of infecting other files or computers.īurn this ISO image to a CD, insert it into the infected system's CD-ROM drive, enter the PC's BIOS, set it to boot from the CD and reboot the computer. ![]()
