Install Ubuntu 5.10 on external usb hdd driver on HP NX6130

It's a success that I had installed ubuntu 5.10 on my external usb hdd driver.
My external hdd driver is Samsung MP40H, 40G.

Dirver	Size	Mount Point	Note
/dev/sda1	20G	FAT32	First primary partition
/dev/sda2	100MB	/boot	Second primary partition, BOOTABLE
/dev/sda5	5G	LVM	First LVM PV
/dev/sda6	6G	LVM	Second LVM PV
/dev/sda7	512MB	/swap	Swap partition
/dev/sda8	8G	/	/ partition

Details of my laptop:

1. Modal: HP NX6130
2. CPU: Pentium M 1.73G
3. RAM: 256MB DDR2
4. HDD: seagate 40G
5. LCD: 14ins

Tips:

1. HP nx6130's bios setting is easy to use. My boot options are first: cdrom, second: hdd disk driver, third: notebook hdd driver.
2. Run the following commands after system reboot.

   $chroot /target
   $mount -tproc none /proc
   $mount
   $mount /dev/sda2 /boot # My /boot is on /dev/sda2
   $df                    # Check if /boot is mounted
   $fdisk -l              # List disk partition in the box.
   	

3. $vi /etc/mkinitramfs/modules
   Add following module word by word.
   ehci-hcd
   uhci-hcd
   usb-storage
   usbcore
   usbbid
   scsi_mod
   sd_mod
   
4. $vi /etc/mkinitramfs/initramfs.conf At the very top of this file, add this line which tells UBUNTU to pause for 12 seconds before starting up ...
   WAIT=12 (in all caps here, not sure if necessary though)
5. Install grub to external hdd's MBR(Main Boot Record)

   	$grub
   	grub>root(hd1,1)  # My /boot is on /dev/sda2. e.g. If yours is on /dev/sda5 (first extended partition), this should be (hd1,4).
   	grub>setup(hd1)   # Install grub to MBR of my external hdd.
   	grub>quit
   	$umount /boot
   	$exit # 
   

6. When the system comes back up it will ask for a partition to mount. Pick the correct mount point for your external drive from the list.
   Mine was mount /dev/discs/disc1/part8 (my / is on /dev/sda8). But yours may be different depending on the number and/or types of drives in your system.
   COMMENT: /dev/discs mount points start with disc0 (with 0 meaning the first drive in a system). So, my mount point of /dev/discs/disc1/part8 was really the second disk [disc1] (the sda drive we are working with) and the / partition [part8] on that disk.
7. Rebuild the boot image.
   $mkinitramfs /boot/init.img-2.6.12-9-386-usb /lib/modules/2.6.12-9-386
8. Edit the GRUB bootloader menu file to correct a small error that looks at the wrong drive to boot from.
   $vi /boot/grub/menu.lst
   There is a line in these three Ubuntu menu choices that has root listed on it and probably has (hd1,0) to the right of it.
   We need to change this to (hd0,1) (This is the partition of my /boot paritition /dev/sda2 ) on all three of these menu choices. Why? Because according to GRUB, the external USB drive will be our first drive (hd0,1) and not our second drive (hd1,0) because we loaded GRUB on it's bootsector.
9. In menu.lst, there is a line "root=/dev/sda8". The root is your / partition.
   And you can add "vga=791" to the line after boot of grub, you can use a monitor resolution at 1024x768 24Bit.
