kernels and boot options

[NZC]

Hi!

I was wondering what the different kernels and boot options does to the installation process. Can any1 please give me a detailed explanation on the different kernels and options ?!

Available kernels. description
gentoo basic gentoo kernel (default)
800 800x600 framebuffer mode
1024 1024x768 framebuffer mode (default)
1280 1280x1024 framebuffer mode
nofb framebuffer mode disabled
smp loads a smp kernel in noframebuffer mode
acpi enables acpi=on + loads acpi modules during init
memtest boots the memory testing program

Available boot options. description
doataraid loads ide raid modules from initrd
dofirewire modprobes firewire modules in initrd(for firewire cdroms,etc)
dokeymap enable keymap selection for non-us keyboard layouts
dopcmcia starts pcmcia service
doscsi scan for scsi devices (breaks some ethernet cards)
noapm disables apm module load
nodetect causes hwsetup/kudzu and hotplug not to run
nodhcp dhcp does not automatically start if nic detected
nohotplug disables loading hotplug service
noraid disables loading of evms modules
nousb disables usb module load from initrd, disables hotplug
ide=nodma Force disabling of dma for malfunctioning ide devices
cdcache Cache the entire runtime portion of cd in ram, This uses 40mb of RAM , but allows you to umount /mnt/cdrom and mount another cdrom.

I can easily see what some of the options are for, like cdcache and dokeymap. But ones like noraid and doataraid I can quite figure out what does

Hope u can help

No detailed explanation, but as a general rule: if you never heard about it, you would probably not need it

It does not really matter what kind of kernel you choose here, as long as you can boot. It does not influence the installation in any way and in the end you want to build your own kernel anyway.

So, the 800, 1024, 1280, nofb only choose diferrent resolutions in your installation shell (nofb if you have troubles with your video card).

smp if you have multiple processors.

acpi hmmm, I can't really say, what diffenrence it makes.

memtest if you want to check your memory.

ataraid, if you need to install on an IDE Raid system, you would know if you did, believe me

The other options are only here for troubleshooting, for example if your dhcpd is behaving weird or if your disks hang on dma access, things you can try, if the boot process hangs.The rest is pretty self-explaining.

If you can boot, be happy, install, build your own kernel.

I have had a search for and could not find... what does the noapm option do ?

EDIT: Apologies, is it 'Advanced Power Management' for laptops ? (thanks Acronym Finder)
