 Posted: Thu Feb 08, 2007 3:55 pm Post subject: Installing with LiveCD 2006.1 [SOLVED] |
 |
|
I installed Gentoo using the LiveCD 2006.1, I chose to use the LiveCD-kernel because the gentoo-sources (I wanted to use) installed fine but resulted in not finding my boot-partition at boot.. (problem with SATA-disks?)
Somewhere I read the LiveCD-kernel is the same as the gentoo-sources only compiled (obviously), I (being Gentoo-n00b) don't understand how come the gentoo-sources don't work where the LiveCD-kernel does.
I want to have a custom compiled kernel but bump into the same thing again and again (no bootpartition found) and would like to know how the LiveCD-kernel is compiled, so I can use that as a base to start from.. I understand the LiveCD-kernel-source is not available but maybe the conf-settings for genkernel???

the livecd kernel is gentoo-sources compiled with genkernel to support just about anything. 
so either you are leaving some necessary support out when building yourself or your grub boot line is incorrect.
you can save your genkernel configuration file anywhere by using | Code: | | genkernel --menuconfig all |
and selecting "save configuration to an alternate file" maybe /usr/src/.config so you will have it to compare.
lspci will tell you most of what support you need for your chipset etc.
you can emerge gentoo-sources and use the make oldconfig command in the src dir ..

Areyou 100% sure you set up the boot partions with correct? and configed grub correctly?

Thanks for the info..
Correct me if I'm wrong but this also means that I can't compile a custom-kernel based on the .config of the LiveCD-kernel? Since there is no source and (I assume) no .config-file? So for now I have no choice than to start from scratch? |

The kernel on the LiveCD is linux-2.6.17-gentoo-r7 which corresponds to sys-kernel/gentoo-sources-2.6.17-r7.
The minimal install CD uses the same kernel and the procedure to compile your own kernel for your new installation is to run | Code: | emerge gentoo-sources
zcat /proc/config.gz > /usr/share/genkernel/x86/kernel-config-2.6
genkernel all |
This will install gentoo-sources-2.6.19-r5 (the latest stable) and then use the 2.6.17-r7 config to configure it. Unfortunately, SATA drivers are configured in the 2.6.17-r7 config but this doesn't transfer to 2.6.19-r5 and no SATA support is compiled.
The LiveCD probably does the same thing and you will need to try and persuade it to emerge the 2.6.17-r7 kernel instead of the latest stable using | Code: | | emerge =gentoo-sources-2.6.17-r7 |
instead which will give you a kernel with SATA support. Unfortunately, I don't know how the LiveCD works so I can't give precise instructions.

| Which compiler flags?? Iquiring minds want to know... I can't see my DVD when I boot my kernel, only in the live cd boot. Argh! |

You're probably missing SCSI CD-ROM support | Code: | Device Drivers --->
SCSI device support --->
<*> SCSI disk support
<*> SCSI CDROM support |
