BTW i think i figured out why i never got my USB mouse to work

I FORGOT TO MOUNT /BOOT AT STARTUP!!! so whenever i copied bzImage to /boot it never reached my boot partition

I'm learning at least. ;)

I don't think you're supposed to mount /boot -- grub should know on what physical partition your boot stuff resides. At least I think.

Click to expand...
cp /usr/src/linux/arch/i386/boot/bzImage /boot

that would need /boot mounted, right?

I don't think so because the 2nd stage boot loader has to find the kernel file before it could boot it.

How could the kernel mount a filesystem before it (the kernel) was ever loaded? :p

From the gentoo install guide, fstab section:
"Warning: Please notice that /boot is NOT mounted at boot time. This is to protect the data in /boot from corruption. If you need to access /boot, please mount it!"

Maybe Gentoo is different, I would for sure make /boot part of /

fstab doesn't take effect until near the end of booting.

Gentoo has you make /boot a seperate partition.(It isnt nessecary though, but they dont tell you that.) Its a good idea, actually, if /boot is part of /, and your computer crashes, its possible to loose data (read: kernel image), but this way with it normally unmounted, it lowers the risk of loosing your kernel image by alot. You tell grub to run on your /boot partition...
hd0,1 is my /boot partition

grub> root (hd0,1)
grub> setup (hd0)

You just need to mount /boot when you copy your kernel image to it, and setup grub.

emerge grub works fine
then i run "grub" and it just dies on me, spits out an error message, and forces me to hit the reset button (the cursor keeps flashing, but no amount of keyboard input will do anything)
i took a picture of the error....

It's done this twice!!

What cflags are you compiling with? If you are using something radical, change them to something like "-mcpu=i386" and recompile grub.

nothing radical.
it actually worked fine when i compiled with
CFLAGS="-march=athlon-xp -m3dnow -msse -mfpmath=sse -mmmx -O3
-pipe -fforce-addr -fomit-frame-pointer -funroll-loops -frerun-cse-after-loop
-frerun-loop-opt -falign-functions=4 -maccumulate-outgoing-args -ffast-math -fprefetch-loop-arrays"

now i'm using
CFLAGS="-march=athlon-xp -O3 -pipe -fomit-frame-pointer"
and it doesn't work :(



i think it's gone crazy, i actually tried to ctrl+alt+del in the middle of an installation at the command prompt and it spit out that error again. I'll check stability tomorrow.

Yes, copying the new kernel would require /boot to be mounted. However, booting does not require mounting since grub ignores /etc/fstab.

...so everytime i recompiled the kernel, i never actually installed it over the old one.

:eek:

Its a good idea to put /boot on a seperate partition. Grub/lilo dosen't care about fstab. You point them at the partition your kernel image is at, and then pass the kernel the device associated with your root partition.

Anyway, on pretty much every distro I've seen, file systems get mounted pretty much right after your kernel loads, not towards the end of the boot :) Otherwise, it wouldn't have access to anything that would allow it to actually boot ;)

never, ever mount /boot unless you happen to be using it. Why? If you start randomly deleting things on you hard drive by accident, you won't delete your kernel :)

Guess who has a working USB mouse!! :D

hey notfred, i guess the reason it wasn't working was the fact that I never actually installed the new kernel. ;)

emerge kde is doing its thing, hopefully it will be done tonight.

Reinstalling Gentoo - again.
Hopefully it'll work this time. ;)
edit: SAME ERROR AGAIN WTF!!

Anybody want to bother to help me set up a non-root user? I know you aren't supposed to run as root all the time, but I have no idea how to make myself a user account that balances power with safety correctly. =\
