I'm trying to work out why some users can boot ok from cd/dvd while others cannot.

For those that cannot, here are some boot cheats that might work

bdev=/dev/sr0 OR
bdev=/dev/dvd OR
bdev=/dev/cdrom

blab=MX-14-live

 
No luck with any of those.

Thanks for this, anticapitalista; unfortunately they didn't work for me. I raised a post about my problem, but this has been removed (or I can't find where it has gone).

Essentially though, the only time I have had this problem, is with Arch based distros and I have sometimmes had to use
I'll have a look at this again tomorrow, no time tonight.

Many thanks,

Chris.

IDE vs. SATA?

Would introducing a delay help? Something like rootdelay=10 I've never seen this fix the problem, but I've seen people recommending it... so who knows.

It will search for the bootdevice for 15 secs to begin with, it never finds the drive. I doubt adding 10 secs will help. Worth a shot though. I'll give it a whirl

Nope, rootdelay didn't help.


Just to be as detailed as possible, who knows it might help:

Once you hit enter on the bootscreen the counter goes to 100, loading kernel. Then it stays stuck on that 100 for a while, and all that time the light of the drive that the disk is in is on.

As soon as the screen goes black and proceeds to display the booting process the light goes off, and it will stay that way.

Another cheat

find=all

If that fails, then we need serious debugging.

Add this bp=2 then at the screen type lsmod somehow copy the info.

Also try bp=2 then type find /dev/ -type b | egrep -v "/ram|/loop"

or simpler find /dev/ -type b

The find command errored.

Here is the result of the requested commands: sda is my harddrive that I am typing this from now (sig line system)
sdb is the USB external drive

Thanks Eadwine, the device is not being picked up.
