Searching for a rescue system that creates a bootable CD to restore my system i found mkcdrec. Because sometimes things (mkcdrec/debian/ubuntu) changes and i had to test and patch for new mkcdrec versions, so i droped it.

Then i started to make a live CD with debian-live and make my install script by myself. I also dropped it (long boottime and had too much to hack to let it work like i wanted).

Now i had the idea to build my own script that tar's my system and builds a bootable cd. I liked the idea of initramfs to extend it like i will and it boots much faster. The only drawback is that all things are hardcoded and have to be changed for every system i backup. But its only a single script: Read More...

get http://mcentral.de/hg/~mrec/em28xx-new/ ... tip.tar.gz and untar

cd em28xx-new-*
make
find /lib/modules/$(uname -r) -name "em28xx*" -type f | xargs rm -rf
find /lib/modules/$(uname -r) -name "tvp5150.ko" -type f | \
xargs rm -rf
mkdir -p /lib/modules/$(uname -r)/empia
cp *.ko /lib/modules/$(uname -r)/empia
cp tvp5150/tvp5150*.ko *.ko /lib/modules/$(uname -r)/empia
strip -d /lib/modules/$(uname -r)/empia/*.ko
depmod -a

/etc/modprobe.d/local

options em28xx card=14 vbi_mode=0 alt=4
options em28xx card=43 vbi_mode=0 alt=2

These two options lines are really working

With alt i use a lower bandwidth for usb

For Kernel >= 2.6.27 card indexes changed, no alt setting is needed and only one option line in /etc/modprobe.d/local is working:

options em28xx card=9,38
