Listmates,
I can't recall who suggested it, Aaron or Patrick, but somebody made
the suggestion to get a simple use to ide adapter to access spare laptop
drives, etc. Well, I purchased one, and it is absolutely the sharpest
thing since sliced bread. I have several drives for my laptop and
murphy's law dictates that what you need is always on the other drive
(theme, notes, etc.)
I connected the usb cable to my spare 2.5 inch drive, changed the bios
to boot from (1) removable devices (2) hard disk (3) cd/dvd drive (4)
network. (Laptop is a Toshiba P35-S629) I turned the computer on, the
usb drive started right away and it looked like the system was booting
from the usb drive. However, the system booted from the installed hard
drive instead.
The usb drive was mounted automatically as:
media/disk /dev/sdb7 spare 10.3 /home
media/disk-1 /dev/sdb6 spare 10.3 /
media/xpdrive /dev/sdb1 spare 10.3 XP partition
Is there a grub boot parameter like (boot=/dev/sdb6) that will tell
grub to boot from the usb drive? The reason being is that I would like
to boot the install to update it. Any help will be appreciated and thank
you whoever it was that recommended the usb to ide solution!
I too would like to see this. I use both USB and Firewire enclosures that
I would occasionally like to boot.
But I'm betting you won't get that to work because you would have to load some
software just to get it to see that drive, and I'm not sure those
pieces are going to
be in the initrd.
I've booted the CDs / DVDs via an external USB optical drive numerous
times, so I suspect the initrd has all the pieces for working with USB
connected drives.
Most likely just a matter of editing the right grub entry and the
fstab on the external. I havn't tried it, but it does not sound that
hard.
Default kernel doesn't have everything necessary for
USB disks... the USB module has to be loaded up...which
then creates a chicken and egg problem.
So, part of the solution is recompiling the kernel
to include the USB module (and all the others which
the USB module depends on).
Because USB ports are more common than parallel ports
now, and especially USB devices, I would like to see
the USB module compiled into the default kernel,
rather than USB being a "2nd class" form of I/O.
As long as it's still maintained as a module, the
embedded systems projects can still choose to leave
it out of their default builds if they so choose.
