[YLUG] Grub

[Dr P Dupre]

Hi Mike,

Thank for the advices. Before I do more, I just want to understand xen ?
I do not know this "word" sorry.
I am not going to do anything on the laptop before a 2 weeks.
Do get additional RAM, what was your recommendation ?

This what I get and this is correct

/var/cache/yum/updates/packages/kernel-2.6.22.9-91.fc7.i686.rpm
/var/cache/yum/updates/packages/kernel-doc-2.6.22.9-91.fc7.noarch.rpm
/var/cache/yum/updates/packages/kernel-headers-2.6.22.9-91.fc7.i386.rpm

I also have the option to recompile a kernel. Before the FC7 I used to do
it (ie. in FC4). Do you know the option to make the "standard"
(like in the distribution) kernel ? which .config file, is the one
is 2.6.23-...  OK ?

Regards
