[aclug-L] Re: Possible meeting topic--What makes a computer

What I read that sun is doing, is the pc is a paper weight and when you turn
it on, it goes to the server and loads the os then at that point you choose
your application and it downloads.  I am speaking of modern applications.
My thought is that a virus cannot live, it the entire os dies each day.  It
is just a thought anyway. It just seemed like an interesting subject, I was
reading about sun on tech republic, I wondered if anything similar was going
on with Linux.  I myself have discovered ssh sessions, they are neat but
offer challenges for security reasons.

What exactly is your question?  Booting a PC from the network is not 
really really fundamentally any different than booting it from local 
media. 

The minimum required to boot a "PC" (by which I mean any "IBM-PC" 
compatible computer) is probably about 256kb of RAM (maybe less, if you 
can find a DOS network driver that will fit in 128kb or 64kb of RAM), an 
8088 or 8086 CPU, and a NIC with a boot ROM.  With that, you could do a 
DOS netboot from a TFTP server, and get a C:> prompt.

If you're talking about something more "modern"... If you want to boot 
Linux on a PC, you need about 8mb of RAM, same as when booting from a 
hard drive.
