My first compiled Kernel.

Hi Guys,

1st Question:
I just playing with the source for the version 2.6.8
I made it fater use "make menuconfig"
I just selected k7 like my procesor type (I have an AMD Duron)
Now, I am working with a dual boot (the other is WinXP for my wife until I can get over it)
Then I configured my lilo.conf (that was a terrible experience, because at a moment I thougth I lost everything and I had to boot twice with the flopy disk before I could fix it)
But the new kernel show this message:

VFS: Cannot open root device "304" or unknown-block(3,4)
Please append a correct "root=" boot option
Kernel panic: VFS: Unable to mount root fs on unknown-block(3,4)

Could you help me out? The old one is still working fine (v2.2.0), cause I don't think that is a problem in the lilo.conf file.

2nd Question:
Other question is. I have a AMD Duron as CPU, a NIC Realtek, a MSI KT3 Ultra as motherboard, a GeForce4 MX 420 as Video Card, etc. But I just could find the processor in the "make menuconfig" menu. How could make a kernel-image more exactly to my needs?

Salu2!

So the lilo entries for both the old and new kernel look similar? What filesystem is your root directory on, and do you have support for it in your new kernel?

Glup!!

This is my currect lilo.conf

lba32
boot=/dev/hda
root=/dev/hda4
install=/boot/boot-menu.b
map=/boot/map
delay=20
prompt
timeout=150
vga=normal
default=WindowsXP
image=/vmlinuz
label=Linux
read-only
image=/vmlinuz.old
label=LinuxOLD
read-only
other=/dev/hda2
label="WindowsXP"

And /dev/hda4 is ext2. How could I know If my new kernel support it?

Salu2!

I saw this in my .config file

# CONFIG_IDE is not set

Is There any relation?

Salu2!

Probably - do you have the source tree for the old kernel? If not, and you're using a vanilla kernel you'll need to set a lot of things up to make it all work.

Go into Device Drivers->ATA/ATAPI/MFM/RLL support and make sure at least the first two items are checked. I don't have time to go over the complete settings right now, but I'll try to post something tonight or tomorrow if nobody else does - I assume the IDE controller is onboard your motherboard?

I would say this is your problem. Without IDE support the kernel cannot read your HDD.

A good idea would be to copy the .config file from your old kernel source to the new, and run "make oldconfig". Now the kernel settings will default to the old ones. Now run "make menuconfig" or "make xconfig" and make your adjustments.
