Hi,
I'm looing for a Linux-system that can boot from an USB-hard-disk. Via a Google I found Grml. But I have some problems with this. So please allow me to describe the system, the problems etc.
My system: Aldi offered a notebook in may 2006 and I bought one. This is my system, if you need more information about it let me know.
What I did: I downloaded the grml.iso-file via grml.gwendoline.at, burned a Cd and started the notebook: works, fine. I added my external hard-disk via USB ( I removed the internal hard-disk for safety, I want to keep the installed XP) and installed the software via grml2hd: works, fine.
For a test I stopped the machine, removed the CD and started it again. In the BIOS I've checked 'boot from USB-device' already and voila: it worked.
The next day I wanted to do this again: problems. So please allow me to describe my problems.
problem #1: the inital screen comes up with the 3 choices. By doing nothing the choice 'grml' was started. Next was a scrren with the text: loading 2.6.18-grml, followed by approx. 180 dots (takes 10 minutes or so). What's this? At the end of this a message was displayed: BIOS data check succesfull (or something similar).
Now we come to the booting-process. This works, a lot of lines are running on the screen. But we come to problem #2: a message appears: usb 2-2: reset high speed USB device using ehci_hcd and address 2 This will be repeated multiple times, some other messages are appearing and these messages appear over and over again. One of the messages between is: SCSI-error, return-code = 0x00050000
What's this?
Can you please give me a hint. Thanks. AugustQ
PS: on my desktop-machine I can easily switch operating system by removing the hard-disk (power off). I'm looking for a similar solution for my notebook. Opening a bay and swapping the disk is possible but I don't want it this way.

Loading of the kernel and initrd - takes a while on external devices with lilo. Maybe using Grub instead is worth a try.

Sorry no idea yet. Can you please provide me a screenshot of the booting process where it hangs? (Please put the screenshot on a webserver and don't send it directly to the mailinglist, either use a public image service if you don't have webspace on your own or please mail it to me off-the-list.)
Oh, and you might want to try to use root=UUID=... instead of root=/dev/sd[a-z]... so you can make sure your system uses the correct device for booting.
