Could these problems have something to do with the fact that the memory
resident SRM code is relocated to upper memory by Linux when it starts, then
restored to lower memory when it shuts down???

I've performed a series of experiments and here are the results:
(The latest SRM for AlphaPC164 is 5.5-1...)
If the system is powered down after setting the boot
variables (without booting) those variables remain
set when the machine is powered up later.
However, those variables are reset to default when
the machine is allowed to boot to Linux, followed
by a "shutdown -h now" and a power down.
The variables remain set to the values I set them to
after the halt, but are reset to default following
the power down.
Put simply: The boot variables become volatile after
the machine boots to Linux. The boot variables appear
to be non-volatile as long as the machine is not booted.
BOOT_RESET..? I can't find it documented in the
"Alpha SRM Consol for Alpha Microprocessor
Evaluation Boards" manual. Anyone?
