Hi,
I just recompiled the kernel on a Red Hat 6.1 machine:
dual piii 600 mhz
512 mb ram
1 gb swap
1 scsi-2 18 gb hard drive (/dev/sda)
1 ide 10 gb hard drive (/dev/hda)
kernel smp 2.2.12-20
The os is installed on /dev/sda, where /dev/sda3 is the root partition.
I encountered no errors during the kernel compile. I copied the new
kernel image to a floppy, and tried to boot the new kernel from the
floppy. During loading (Loading...), I got an error message saying,
"Out of memory, system halted". So then I tried booting the new kernel
from the hard drive. I put in a new stanza into /etc/lilo.conf for the
new kernel. Here's my /etc/lilo.conf:
boot=/dev/sda
map=/boot/map
install=/boot/boot.b
prompt
timeout=50
default=new
image=/usr/src/linux/arch/i386/boot/bzImage
label=new
root=/dev/sda3
image=/boot/bzImage-2.2.12-20-111200smp
label=jonesy
read-only
root=/dev/sda3
image=/boot/bzImage-2.2.12-20-011800smp
label=221220smp
read-only
root=/dev/hda3
image=/boot/vmlinuz-2.2.12-20smp
label=linux
initrd=/boot/initrd-2.2.12-20smp.img
read-only
root=/dev/sda3
image=/boot/vmlinuz-2.2.12-20
label=linux-up
initrd=/boot/initrd-2.2.12-20.img
read-only
root=/dev/sda3
When I ran /sbin/lilo, I got this error:
Warning: /dev/sda is not on the first disk
Added new *
Added jonesy
Added 221220smp
Added linux
Added linux-up
"new" is the label for the new kernel I want to boot. What's with the
warning message? fdisk shows this for /dev/sda:
Disk /dev/sda: 255 heads, 63 sectors, 2231 cylinders
Units = cylinders of 16065 * 512 bytes
Device Boot Start End Blocks Id System
/dev/sda1 1 102 819283+ 5 Extended
/dev/sda2 * 103 152 401625 83 Linux
/dev/sda3 153 641 3927892+ 83 Linux
/dev/sda4 642 2231 12771675 83 Linux
I've set /dev/sda2, the /boot partition, to be bootable. But when I
tried booting off the hard drive, I just got a screenful of 1s and 0s,
and the machine is frantically trying to access the floppy drive. I
checked the bios. The boot sequence is set to "A,C", and scsi drives
are to boot before ide. What can I do to boot this new kernel? Thanks,
Hidong
