2. Changing your Bootup Configuration

Resumo

This tool allows you to configure the bootloader and the boot menu entries.

[Atenção]Atenção

Unless you're an expert, it's not recommended to change these settings as this may prevent you from booting your machine the next time you try to power it on.

Choosing the Boot Mode

2.1. Configuring the Bootloader

You can choose between the GRUB and the LILO bootloader. Either one will allow you to boot Mandriva Linux, it's just a question of taste.

Unless you know what you're doing, you shouldn't change the default Boot device shown, since that's where the bootloader installs itself. If more than one OS is installed on your machine, it's a good idea to leave at least 5 seconds so that you can easily select a different menu item than the default image.

The dialog finally shows a few options which can be useful depending on your specific hardware.

Enable ACPI

Enable this option to allow better power management support if your hardware is ACPI compatible. ACPI is often needed for new laptops which no longer support APM.

Force No APIC

The IO-APIC is only really useful for multi-processor systems. It may cause problems on single processor systems and should be deactivated in that case by checking this box.

Force No Local APIC

The Local APIC can be used by Linux to program interruptions to wake up threads. On multi-processor machines it can be used to send interrupts to another processor.

These relatively new APIC features are known to cause problems on some computers because of badly designed chip sets or poor support in Linux kernel drivers. These problems can cause system freezes or incorrect device detection. So you may need to deactivate them by checking the corresponding box.

Click on Advanced to be able wipe the contents of the /tmp directory (which might hold some files you download from the Internet, for instance) and to tell Linux how much RAM your machine uses should this prove to be an issue at boot time.

2.2. Managing Boot Entries

After clicking Next, the list of available entries at boot time is displayed; the default one is marked by a star (*).

It's also possible to make an entry the default one by checking the Default checkbox in the Modify dialog.
