grub boot screen


im just curious as to when the grub boot loader starts ( dual booting with win xp) there 2 different things for linux. heres what it says:

Red Hat Linux (2.4.20-6smp)
Red Hat Linux (2.4.20-6)
Windows XP

is that normal?

Well, it doesn't say that for me. I've just got one option for each OS. Have you updated your version of RedHat since installing grub? Or perhaps you Reinstalled 2 copies of Red Hat by accident. (Hey, it could happen)

It looks to me like you have 2 different kernel versions for RedHat. One is for a regular, everyday PC with one processor. The other one (with the SMP in it) is for a computer with more than one processor. Symmetic Multiple Processing (I think, or something similar anyway), SMP. I think you know what the Windows XP one does (or I hope so, at least.) Just a note, you can use either version of those two kernels without much of a difference, I think. If you run an SMP kernel, or a kernel with SMP compiled into it, it will still run on a computer with one processor.

Later

i see...well i know its not 2 different copies...maybe it has something to do with the hyperthreading? its a p4 3.0 with ht and from what i understand it makes the os think that theres 2 processors...is there any way i could remove the other one if theres not any difference?

I'm not sure about the Hyperthreading causing your system to think theres more than one processor. Maybe. There is really no reason to get rid of either one of the entries. If you do, however, want to get rid of one of the entries you need to edit your /etc/grub.conf file. Just edit that file and take out which ever entry you want. It won't really make a difference, though. I mean, you will now have only 2 entries on your GRUB screen but both kernels will still be there. I guarantee that you have 2 different kernels.

ok i guess ill just leave them there then its not really a problem i was just curious as to why they were there. and that is what hyperthreading does, makes programs able to execute 2 threads at the same time, essentially the same as a dual processor setup, which is why the os sees 2 processors
