求救！如何在安装时更改启动核心？

我想要在sgi1200（L440GX主板）上安装redhat7.1以上版本，在使用CD安装时，会出现aic－xxx无法通过。根据redhat网站的说法要先使用“linux apic”安装系统，假如是单CPU，必须使用smp的核心来启动，按它的说明要把“default=linux”改为“default=linux-smp”
我对这很困惑，是在安装时，出现设置lilo的页面时修改吗，我是在那里修改的，但仍然没能正常启动，请高手指点，拜托各位了！感谢！付redhat上的安装说明：

Red Hat 7.1 installation instructions
Using the appropriate boot image diskette for your system, when you boot the kernel, use the apic command line option, aka:

boot: linux apic

This will force the UP-IOAPIC code on in the boot kernel and allow the interrupt routing to get properly fixed up. This allows you to install to these machines. However, there is a second issue.


If your machine only has 1 processor installed, then the SMP kernel will not automatically get installed. You will need to enable individual package selection, then go into the kernel packages and select the SMP kernel. You will then need to make sure that when you reboot the machine, you tell it to boot the SMP kernel. You can make the SMP kernel the default by changing the line:

default = linux

to

default = linux-smp

in the /etc/lilo.conf file and then running the lilo command as root to re-initialize the master boot record on your hard disks.



Red Hat 7.2 installation instructions
Use the normal install disks, no special boot disks are needed for Red Hat 7.2. However, you will need to pass the apic option to the kernel on the boot disks, so for example when booting up the install disk you would type something like:

boot: linux apic

This does the same thing as the special 7.1 install disks in that it enables IO-APIC support in the install kernel.


Follow the step 2 instructions for 7.1.
