2.6 kernel for hp laptop

sub_slack · 03-08-2007, 03:07 PM

Hi, i'm trying to install gentoo. can someone help me configure a kernel for my laptop. i partitioned my drive the following way:
/dev/sda5 - /boot, ext3
/dev/sda7 - /, ext3

i also have windows xp on /dev/sda1 and grub works great. the problem is when loading the kernel.
first i used genkernel, when i put all those lines in grub.conf and rebooted it gave me an error at boot time about /dev/sda7 not beeing real root, i searched and found that i had to put scsi support into the kernel, so i tried once more manually configuring and compiling, but some similar error happened, it couldn't mount root.
what should i compile inside a kernel, as a module, and what modules to load? someone help me to configure my kernel (gentoo-sources), i have following specs on my laptop:

Centrino Duo T2050
Processor x86 Family 6 Model 14 Stepping 8 GenuineIntel ~1596 Mhz
Processor x86 Family 6 Model 14 Stepping 8 GenuineIntel ~1596 Mhz

Make sure enable support not as modules but * when you do make menuconfig. That will add support directly into the kernel. Genkernel uses an initrd image to load those modules. Here is mine but for a ati based motherboard with sata.

Code:

In this .config file support that says y is when you do menuconfig it is *
