[NTLUG:Discuss] how to reprogram diskonchip modules

[Ralph Green]

Howdy,
  I have a few thin client machines I would like to setup.  The Neoware
and HP machines have these diskonchip modules in sizes from 64 meg to
256 meg.  That should be plenty of room for an embedded Linux setup to
act as an accesspoint or firewall.  My problem is that I don't see how
to program them.  They have 44 pin female headers.  I find adapters to
let me plug 2.5 inch drives into a desktop PC and those expect male
headers.  Is there some simple part that I should be looking for?  Or,
do people that program these for business use some expensive programmer?
It seems like all it would need it a kind of special, but fairly simple
adapter cable.
Good day,
Ralph Green, Jr
