VoD week

As i'm a little bit sick of lab'in and to not overthrottle myself, I relax this week with some nice VoDs :)

On Saturday i will finish INE Vol2 Lab 7 and on Sunday do TS+Config Lab 8.

Time to decide when to do the Mock Lab ... hmmm. Maybe on 24th of Sept

INE Vol2 - Configuration Lab 7

was just too hot to complete it, but i think it would have been a FAIL.

Difficulty level 9 (which is much more difficult than the real thing)

[OT] Create DOS boot usb-stick for BIOS update under linux

I needed to upgrade the bios of my Computer (Intel).

But how to do it without windows?

Download a FreeDOS image, i'll use Balder for now.
Prepare the usb-stick
check partition (e.g cfdisk /dev/sda)
mkfs.msdos /dev/sda1

Commands

qemu -boot a -fda balder10.img -hda /dev/sda
A:\> sys c:
A:\> xcopy /E /N a: c:

Check with

qemu -hda /dev/sda

All GRML uses should also take a look at http://wiki.grml.org/doku.php?id=biosupdate which provides a nice overview.

That's it!
