boot BackTrack with kexec

[reisub]

hey guys,

i installed BackTrack 5 on a USB-Stick with persistent mode (described here).
But my Thinkpad only supports USB 1.1 due to a flexing problem. So I use an USB2.0 PCMCIA-controller which works correctly with Linux but the BIOS can't boot from it.

So I decided to reboot from my existing Installation (ArchLinux) with kexec directly into BackTrack. I use this command:

kexec -l --command-line="file=/cdrom/preseed/custom.seed boot=casper persistent text splash" --initrd="/mnt/sdb1/casper/initrd.gz" /mnt/sdb1/casper/vmlinuz
kexec -e

At first it seems to work and I can see the splashscreen. But it won't boot any further. When I hide the splashscreen using [Esc] it shows the following error:

[...]
Running /scripts/casper-premount
Done
Done
stdin: error 0
/init: line 3: can't open /dev/sr0: No medium found
/init: line 3: can't open /dev/sr0: No medium found

The last 3 lines are printed every second until I reboot

Does anybody has an idea how to fix this?

ok, I figured it out on myself.
The Kernel needs the PCMCIA-Module but it can't load it from the USB-Stick. I would have to recompile the kernel with built-in PCMCIA-support.

So I will install BT on the harddrive now, much easier this way
