yes. it's created by make menuconfig (or config / oldconfig / config). I've never understood why it's hidden, I would have called it kernel.config. There is also a "live" version that you can find in /proc/config but maybe you've got to compile something in kernel (or it's only for 2.6, I don't remember) > >2. optinal: if you use alsa-driver > ># cd /lib/modules > ># touch 2.4.20-gentoo-r7/kernel/sound > >(should be enough to protect r7's alsa modules, but it would be better to > >backup them) > ># emerge alsa-driver > > I have not installed "alsa-driver" yet.

When I try to install grub, I get stuck in the post-bios-boot-thingy (before bootloader gets loaded) with a blinking cursor at bottom of screen. but, I would do the following. title=Gentoo Linux (genkernel) root (hd0,0) kernel (hd0,0)/boot/kernel-2.4.20-gentoo-r8 root=/dev/hde3 hdd=ide-scsi initrd (hd0,0)/boot/initrd-2.4.20-gentoo-r8 or in vi /Gentoo4yy3jpf(Cgentoo-r9<esc>2j^Aj^A:wq ;-) -- mathieu -- [EMAIL PROTECTED] mailing list
