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. If you are facing an issue that these tips do not address, please visit our Knowledge base or send an email to our technical support service.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. While here, you should choose the administrator account. For that open Settings->Additional->Update setting->User account Settings. Open the Update Settings and check, which access rights are used to run the program. If the energy saving setting (‘Disable scheduled tasks while running on battery power’) is checked, then your antivirus will not update antivirus databases until your device is plugged in.Ħ. For that open the Settings->Performance window. If you use a laptop, check the energy-saving settings of your security solution. In this case you should download Kaspersky Virus Removal Tool and run a system scan.ĥ. If you cannot access any of these links, your PC may be infected with a virus, which blocks access to Kaspersky Lab resources. Follow the links in this article to check if there are any Kaspersky Lab update servers available. Here you can find how to do it for Internet Explorer, Google Chrome and Firefox.Ĥ. Set your browser proxy settings to default values. To do that, open the product’s settings window and click on the Additional->Network Settings->Proxy Server Settings.ģ.

To do that, click on the program icon in the lower right corner of the display and choose ‘Update.’ Or you have a ‘license issue’, try updating your software manually. If your security solution window turns red and and shows the ‘Database extremely out of date’ warning, Kaspersky Lab products update automatically, but sometimes certain issues can happen. Keeping your antivirus databases up-to-date is just as important as the initial install. Installing a security solution is important, however you just cannot assume that you are done there.
