[iPAQ] Installing Linux, step 13

I know this subject was already covered on the linux@handhelds.org-list a
few months ago, but I didn't quite get the answer.. As it turns out I ran
into the problem when trying to do this:

--
This step is dangerous: make sure you perform it exactly correctly. At the
'boot>' prompt, type 'load bootldr', then start an xmodem download of the
file bootldr-0000-2.9.5. A bootldr tarball corresponding exactly to these
boot loader bits is available. 
--
Ok, it loads fine for a while and then I get the TIMEOUT ERROR. There was
a solution on the linux list and this is how I understood it should work:
1. boot> load bootldr
2. ctrl-a s <xmodem> <select bootldr-0000-2.9.5>
3. Let it transfer for a while and stop when you get NAK's (I don't recall
seeing any NAK's. Anyone have more info on this?)
4. boot> load bootldr
5. ctrl-a z s <cr> <cr>. What's this do? 
I'm using minicom as the terminal.
