It's mounting the root filesystem, the boot partition, /proc, chrooting and then | Code: | USE="-doc symlink" emerge =gentoo-sources-2.6.17-r8
zcat /proc/config.gz > /usr/share/genkernel/x86/kernel-config-2.6
genkernel all |
The same sequence as when you first compiled it, just the explicit version number for gentoo-sources.
The commands for mounting, chrooting and so on have been given above for editing lilo.conf and running /sbin/lilo

ok this is what i did i deleted vista   and i'm installing gentoo right now i have to compile the kernel now but i need some help so it doesnt go wrong this time .
here my new partition table:
| Code: | sdb1 = /boot
sdb2= /swap
sdb3 = /root |
i want to know should i use genkernel or genkernel --menuconfig ?
and should i use lilo or grub ? i know this is a choice of the user but you know more of linux then me so could you tell me ?
thx in advance, |

I should use genkernel as kernel configuration is an extra burden you could do without at this stage: just make sure you get the 2.6.17-r7 gentoo sources so it will boot.
There are probably more people here that know about GRUB than LILO so you should find it easier to get help if you choose GRUB.
You say you are installing on sdb, what is sda? The boot loader will usually be installed on sda unless the BIOS sees the disks in a different order.

Well done, you're on the way to becoming a Linux expert: it's all in solving your own problems by finding what others have done and applying it to your own situation.
I've been looking though the posts too: here's one which seems to cover it: look at NeddySeagoon's replies especially https://forums.gentoo.org/viewtopic-p-3051763.html#3051763. You will also find some quite easy to follow stuff about adding the SATA drivers in the KC13 FAQ under "2) Kernel panic â VFS error:" which also has a link (in Resources) to another FAQ on configuring and compiling a kernel.

Well, basicly, have you got two SATA disks? If so, what have you got on the other one?
Two SATA disks because if you only had one it would usually be called sda.

thanks
i read https://forums.gentoo.org/viewtopic-p-3051763.html#3051763 but there's not explained how to rebuild the kernel just how to resume compiling. But if i just do make menuconfig and then make && make modules_install will that recompile ?
and i just have 1 harddrive in my pc... |

Just to dot the i's and cross the t's- chroot as before â NeddySeagoon has a guide for this too NeddySeagoons' Rough Guide to Chrooting except you will have to replace hda by sda, that is, /boot is /dev/sda1 where it is hda1 in the guide
- cd to your kernel source directory
Runand make the changes to the kernel configuration: there are brief navigation instructions at the top of the first frameLeave menuconfig by selecting Exit and selecting "Yes" to save your new configurationCopy the config to /boot under a name which includes the kernel version, for instance | Code: | | cp -pv .config /boot/config-2.6.19-gentoo-r5 |
Runto clean out all the old stuff and start afreshCopy the saved config back in | Code: | | cp -pv /boot/config-2.6.19-gentoo-r5 .config |
Run | Code: | | make && make modules_install |
When compilation is done, save your new kernel to /boot | Code: | | cp -pv arch/i386/boot/bzimage /boot/kernel-2.6.19-gentoo-r5 |
Check that your grub.conf has an entry for the new kernel, if not, add a new section like | Code: | title 2006.1 Gentoo Linux 2.6.19-r5
root (hd0,0)
kernel /boot/kernel-2.6.19-gentoo-r5 |
Make sure that the "root" line is correct for your systemExit from the chrootUnmount /mnt/gentoo/boot, /mnt/gentoo and /procNow you should be able to reboot

and the CD/DVD-ROM drive isn't SATA?

rebuilding went perfect only now i get this
| Code: |
Root-NFS: No NFS server avaible, giving up.
VFS: unable to mount root fs via NFS, trying floppy.
VFS: insert root floppy and press enter
VFS: Cannot open root device "sda3" or unknown-block(2,0)
Please append a correct "root=" boot option. |
and if i press enter i get kernel panic. |

"unknown-block(2,0)" is the floppy drive â it looks as though, for some reason, you have CONFIG_ROOT_NFS selected in your .config and this is causing the error â you have got the SATA support compiled in, not as modules haven't you? If you use "m" to select the options like "< >" you will get a module, you have to use "y" instead. Could you check the settings you have against those recommended in KC13?
One thing that hasn't been shown is the SATA chipset you have: can you run lspci when booted into the install cd and post the lines with either IDE or SATA in them, please?
Could you also post the version of the kernel sources that you are compiling?
Back to NFS_ROOT: when you run "make menuconfig" again, could you navigate to | Code: | -> File systems
-> Network File Systems |
and change | Code: | | < > NFS file system support |
to have the "< >" empty?

i dont have a floppy drive. And i selected all my drivers with y not with m
here the output of lspci:
| Code: | IDE interface: Intel Corporation 82801EB/FBM/FR/FW/FWR (ICH6 family) IDE Controller (rev 03)
IDE interface: Intel Corporation 82801FW (ICH6R/ICH6RW) Sata controller (rev 03) |
and i dont know for sure if < > NFS file system support was enabled. Is NFS file system support not enabled by default ? |

|
then you should have, as well as | Code: | Device Drivers --->
SCSI device support --->
<*> SCSI disk support
SCSI low-level drivers --->
<*> Serial ATA (SATA) support |
| Code: | | <*> Intel PIIX/ICH SATA support |

Well, I didn't look carefully enough to see when the CONFIG_ROOT_NFS option was enabled. You can check very quickly by cd'ing to your kernel source directory and runningIf it doesn't show ROOT_NFS then it's OK. It might show "CONFIG_NFS_FS=m" as this seems to be a default. If it shows ROOT_NFS then you will have to change "< > NFS file system support" to blank and that will remove it.

The settings were copied from the KC13 FAQ â but for kernels 2.6.18 and below. Again from KC13, for 2.6.19 you still need | Code: | Device Drivers --->
SCSI device support --->
<*> SCSI disk support |
You don't need anything under | Code: | | SCSI low-level drivers ---> |
but you now need | Code: | Serial ATA (prod) and Parallel ATA (experimental) drivers --->
<*> ATA device support
<*> AHCI SATA support
<*> Intel PIIX/ICH SATA support |
You don't need NFS support unless you have another machine you are going to mount partitions from over NFS. As you are going to be reconfiguring your kernel, you can remove it if you like.
You also need to have filesystem support compiled in, see KC13 for that.

Could you upload your kernel .config file (/mnt/gentoo/usr/src/linux/.config when booted up to the installcd) and /var/log/messages to http://pastebin.ca and post the URIs you get back?
Instructions are here.
If you go to the bottom of the first page, you will be able to select a shorter time for the files to stay there, a week should do it.

I'm very pleased â and a lot of it is down to your own hard work, too.
Can you post the output from | Code: | | ls -alF /etc/conf.d |
andplease?

| Wynn - Thanks so much for all the help you posted on this thread. I have been plagued for over a week with misc. errors all based around the lack of SATA support when using genkernel (defaults). Since most systems come with SATA drives, do you think the instructions should be ammended to reflect the lack of SATA support in a genkernel default install? Anyhow, thanks again. |
