Dear David,

Glad this is slightly helpful.

Unfortunately, what the BIOS can boot from is usually rather more 
restricted than the list of devices the OS can use once booted.

Does the A21e not have an internal network port on the back of the 
machine? You won't be able to network boot (PXE boot) from a PCMCIA card.

If you're trying to *install* via the network, it needs to be something 
the BIOS can see (it should appear in the boot options as "boot via LAN".

[Not relevant for installation, but may help to know this anyway:]

If you run (as root) the command    ifconfig  -a
you should get a list of all detected devices. It should appear as eth0
or possibly eth1.

If you then run     ifconfig      (without the -a switch), it will list 
the devices which are currently online.

Use           dhclient eth0         to obtain a network connection.

Then I could do a

You need to use ssh.  Is the other laptop running Linux, or Windows?
Will the internet cafe let you install programs on their Windows 
machines? Will they let you download up to 2 GB of data?

No. Essentially, during an install, everything that actually matters 
lives in RAM. Providing you don't kill power midway through, by the time
the install is finished, everything will be written out to disk.

That should be workable, but it could be tricky. Try doing this:

Would suggest you go for Ubuntu in the end.


In summary, I think you have these options:

* Try moving the disk temporarily to the other laptop. Use its CD to do 
the install. Move it back.

* Use your other laptop to install Ubuntu onto a pendrive. [You'll need 
a 4GB pendrive for this to work, unless you are comfortable with doing a 
server-install]. Then, copy the newly installed system onto your A21e.
You can use your damaged linspire installation to copy across.

* Network install onto the A21e. (Requires an internal network card, NOT 
a PCMCIA one).

* Buy, or borrow an internal CD-ROM for the A21e. Quite cheap on eBay.
This may, in fact, be the easiest way for you to get everything working.

* Buy a USB-HDD enclosure for your A21's disk. (Cost about $10). Then, 
plug that into your other machine. Boot the other machine with the 
Ubuntu installer. Then, install onto the A21's disk. [Be *careful* not 
to install on the wrong disk!]


Essentially, you have to decide to either:

1)Find some way to install direct onto your laptop's disk, either by 
moving the disk to a different machine, or by finding a device the BIOS 
can boot.

2)Use your damaged linspire system to copy a complete installation over 
from somewhere else. You need a fully installed and working Linux system 
to copy from.

3)Try to repair the linspire system. If it boots up as far as a root 
prompt, it is possible to fix it. Does Linspire use xorg, or XFree86?
To find out, run
    ls /etc/X11/xorg.conf
and
    ls /etc/X11/XF86Config-4
Then, (take a copy first), and edit that file. You could also try moving 
it somewhere else, leaving nothing in its place. See whether the system 
is smart enough to regenerate a default file for you on reboot.


Lastly, this page may help you. It's my documentation of the A22p, which 
is quite similar to the A21e. It refers to Mandrake 2006, but some of 
the stuff there may be of use.

P.S. How comfortable are you with using (or learning about):
    bash, rsync, ssh, mount, mkfs, fdisk, nano  ?

Your problem is soluble, but it's going to be quite advanced to fix.
The "wizardy" is quite fun to learn, but there is a fair amount of it 
that you'll need. So, do decide what you want to do.

The simple/quick way is to buy some more hardware - either an ultrabay 
CD-ROM, a large pendrive, a USB->Mini-IDE adapter (i.e. a USB hard disk 
enclosure for laptop size disks), or a thinkpad mini-PCI card with 
network/modem.
