kernel-generic-smp-3.2.45_smp-i686-3
and create a initrd for kernel 3.2.45 not 3.2.29

It does not work. I booted into my hard disk salixos installation and installed kernel-generic-smp-3.2.45_smp-i686-3 and kernel-modules-smp-3.2.45_smp-i686-3 and gave the command: "mkinitrd -c -k 3.2.45-smp -m ext4 -f ext4 -r /dev/sdb1". This created the initrd.gz file in /boot folder of hard disk which I transferred to /boot of usbdrive alongwith vmlinuz-generic-smp-3.2.45-smp file. I then corrected the grub-legacy menu.lst file and booted from usbdrive but got the error that /dev/sdb1 is not mounted. I am dropped in a limited shell. The /dev/ folder shows that all sda partitions are present but no sdb partition. Did I do any step incorrectly?

Are you sure your usb drive is /dev/sdb?

You would also need to transfer all kernel modules if you're doing it that way.

A simpler way, that actually installs the packages, would be to use the --root option of spkg to specify your mounted usb drive, or to chroot into your usb drive and do everything from there.

How to boot salix from an external usb disk.

These has been tested and work
(/media/57ab93a9-ed94-44e3-984d-76b1b0826d98 is where is mounted my USB_stick. On a salix 14.0.1 kde installation). Replaced with yours.
We do not need generic kernel. the installed kernel-huge-smp-3.2.45_smp-i686-3 is what we need.

1. First install salix 14.0.1 from a livecd or a installation cd to the external disk drive. We do not install lilo since we will use grub to boot.
2. We also need an existing salix 14.0.1 installed to a hard drive.
3. We boot on our salix 14.0.1 hard disk installation.
4. Then we chroot to external usb disk where salix is also installed.

Code: Select all

su
mount -o bind /dev /media/57ab93a9-ed94-44e3-984d-76b1b0826d98/dev
mount -o bind /proc /media57ab93a9-ed94-44e3-984d-76b1b0826d98/proc
mount -o bind /sys /media/57ab93a9-ed94-44e3-984d-76b1b0826d98/sys
chroot /media/57ab93a9-ed94-44e3-984d-76b1b0826d98 /bin/bash
cd /boot
mkinitrd -c -k 3.2.45-smp -f ext4  -m usbhid:ehci-hcd:ext4 -u -o /boot/initrd.gz
exit
Now we edit our grub.cfg and add these lines

Code: Select all

menuentry "Slackware Linux (Slackware 14.0) (on /dev/sdb1)" {
	savedefault
	insmod ext2
	set root='(hd1,1)'
	search --no-floppy --fs-uuid --set 57ab93a9-ed94-44e3-984d-76b1b0826d98
	linux /boot/vmlinuz-huge-smp-3.2.45-smp root=/dev/sdb1
	initrd /boot/initrd.gz
}
Reboot
and boot on your external USB disk with salix.

I am writing this message from my USB stick installed salix-14.0.1-xfce-32 after booting with initrd.gz and grub.

Should this work the same using an external hard disk connected via USB? If so, I'd be interested in giving it a try :)

Yes, it worked. The huge-kernel together with initrd created using the mkinitrd command given above is needed to boot from a usb drive. The generic kernel does not work with this initrd.
