Bootable Ghost USB key

Today I was trying to create a Bootable DOS USB thumbrive for restoring my GHOST partition, I search many times but cannot find a good solution. Finally, I solve it after many hours.

Hence to document it down.
Most of the instruction is from: http://visibleprocrastinations.wordpress.com/2007/09/13/build-yourself-a-bootable-ghost-usb-key/

The problem is I do not have floppy drive anymore.

1. Download and install HP flash drive creation tools (both)

a. HP USB Disk Storage Format Tool

b. HP Drive Key Boot Utility Version 7.41

2. Next download a win98SE setup flash image because only win98 support USB drive.

3. Finally download bootkey that automatically configure for GHOST
Instruction as per http://visibleprocrastinations.wordpress.com/2007/09/13/build-yourself-a-bootable-ghost-usb-key/

4. Since I do not have a floppy drive this is what I do.
Step 1 -> Format your thumbdrive using the installed "HP Drive Key Boot Utility"(from 1b)


Step 2 -> Using the win98SE image from 2.

Step 3 -> Remove and reinsert your thumbdrive, then copy all the content including system files into a directory.

Step 4 -> Now using "HP USB Disk Storage Format"(from 1a) to again format your thumbdrive, selecting the system files from Step 3.

Step 5 -> Finally copy the files from bootkey (from 3) into the thumbdrive including the ghost.exe into the correct folder.

You are now ready to go.

Adaptive Codecs for different devices from PDA, handphone to laptop

Recently, I saw a presentation from a local research institute on an adaptive codec that they are developing.

Today if you have video content that you will like to provide for your users' devices like handphone, laptop or DVD player, you will need multiple files.
Eg. your handphone might only support QVGA (small size video) while your laptop can display in High Definition, and DVD can only take Mpeg2 and DIVX. So what do you need if you are the content provider.
- You need to store different files for different devices.

However with the new codec container, you only needed to store the picture once, depending on he device connected, the container will release the correct files. This will speed up the overall download speed as well as format type.
