I have thought about getting a portable 386 box to run UNIX on, but I
didn't want to have to ballance a spinning hard disk on my laps.
Reading about RAM-DISK drivers gave me an idea about building a
transportable, shake-able, kick-able, virtually indestructible :-) UNIX
box, whose root partition resides on a ROM-DISK.  Given that there
exists a working RAM-DISK driver, it should be pretty simple to modify
the dirver to treat a block of ROM as a disk.  User who wants to build
a ROM-DISK can first create a RAM-DISK, copy all the necessary files
into the RAM-DISK partition, then burn the content of the RAM-DISK into
ROM.  Does anyone know whether UNIX can be booted off a ROM disk?  Does
Driver Design Labs plan to provide ROM-DISK drivers?  Personally, I
have never touched a 386 box, so I do not know whether any of this
makes sense.
