The Question is:
I am working on a device driver and need to reboot my development Alpha (an
AlphaStation 200 4/233) quite often. I need to have the hardware in a known
state and I have been shutting down, halting and >>> INITing the Alpha to do so.
My question is:
Is there a way to issue a VMS "REBOOT" and have the equivalent of the console
INIT command be issued prior to the system bootstrapping itself? If I could
do this, I could walk away or work on other tasks while awaiting the reboot.
Now, I have to wait
for the shutdown, INIT manually, and then boot.
The Answer is :
The console variable "boot_reset" may do what you want. When this variable
is set to "ON", the system will automatically perform a reset during the
Note that if the kernel code sufficiently disrupts the state of the PCI bus
hardware, there are cases where you may well be left with a manual reset (via
the front panel switch or via power-cycle of the system), as certain Alpha
systems use a particular chipset tied to the PCI reset signal, and this
chipset will react to a PCI reset signal assertion by disconnecting the
memory, BCache and PCI from the Alpha microprocessor. This will obviously
leave the Alpha microprocessor with no ability to recover from the PCI reset.
Products that will not automatically reset the PCI bus via software -- without
the use of a button (or the power plug) -- include:
